• how to achieve Inter-Widget communication

  - by bakore

  I was looking for a platform where widgets developed using various technologies like Java can communicate with each other. In other words When I add widgets to an interface I need them to talk to each other. For example A Click event in one widget should trigger an event in some other widget. I have been looking into the web for solutions and ways to do it, but couldnt find anything concrete. Any pointers or information on this would be great. Something like this http://blogs.sun.com/pdblog/entry/inter_widget_communication_in_cross

• Will Sytem.currentTimeMillis always return a value >= previous calls?

  - by 1984isnotamanual

  http://java.sun.com/j2se/1.4.2/docs/api/java/lang/System.html#currentTimeMillis() says: Returns the current time in milliseconds. Note that while the unit of time of the return value is a millisecond, the granularity of the value depends on the underlying operating system and may be larger. For example, many operating systems measure time in units of tens of milliseconds. It is not clear to me if I am guaranteed that this code will always print ever increasing (or the same) numbers. while (1) { System.out.println(System.currentTimeMillis() ); }

• C++ vector insights

  - by Sunscreen

  Hi, I am a little bit frustrated of how to use vectors in C++. I use them widely though I am not exactly certail of how I use them. Below are teh questions? If I have a vector lets say: std::vector<CString> v_strMyVector, with (int)v_strMyVector.size > i can I access the i member: v_strMyVector[i] == "xxxx"; ? (it works, though why?) Do i always need to define an iterator to acces to go to the beginning of the vector, and lop on its members ? What is the purpose of an iterator if I have access to all members of the vector directly (see 1)? Thanks in advance, Sun

• Generic type parameter naming convention for Java (with multiple chars)?

  - by chaper29

  In some interfaces i wrote I'd like to name generic type parameter with more than one character to make the code more readable. Something like.... Map<Key,Value> Instead of this... Map<K,V> But when it comes to methods, the type-parameters look like java-classes which is also confusing. public void put(Key key, Value value) This seems like Key and Value are classes. I found or thought of some notations, but nothing like a convention from sun or a general best-practice. Alternatives i guesed of or found... Map<KEY,VALUE> Map<TKey,TValue>

• Java Thread wait() => blocked?

  - by Chris

  According to http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Thread.State.html calling wait() will result a thread to go in BLOCKED state. However this piece of code will result (after being called) in a Thread in WAITING State. class bThread extends Thread { public synchronized void run() { try { wait(); } catch (InterruptedException e) { e.printStackTrace(); } } } Have I got something wrong? Can anybody explain this behaviour to me? Any help would be appreciated!

• The Oracle Enterprise Linux Software and Hardware Ecosystem

  - by sergio.leunissen

  It's been nearly four years since we launched the Unbreakable Linux support program and with it the free Oracle Enterprise Linux software. Since then, we've built up an extensive ecosystem of hardware and software partners. Oracle works directly with these vendors to ensure joint customers can run Oracle Enterprise Linux. As Oracle Enterprise Linux is fully--both source and binary--compatible with Red Hat Enterprise Linux (RHEL), there is minimal work involved for software and hardware vendors to test their products with it. We develop our software on Oracle Enterprise Linux and perform full certification testing on Oracle Enterprise Linux as well. Due to the compatibility between Oracle Enterprise Linux and RHEL, Oracle also certifies its software for use on RHEL, without any additional testing. Oracle Enterprise Linux tracks RHEL by publishing freely downloadable installation media on edelivery.oracle.com/linux and updates, bug fixes and security errata on Unbreakable Linux Network (ULN). At the same time, Oracle's Linux kernel team is shaping the future of enterprise Linux distributions by developing technologies and features that matter to customers who deploy Linux in the data center, including file systems, memory management, high performance computing, data integrity and virtualization. All this work is contributed to the Linux and Xen communities. The list below is a sample of the partners who have certified their products with Oracle Enterprise Linux. If you're interested in certifying your software or hardware with Oracle Enterprise Linux, please contact us via [email protected] Chip Manufacturers Intel, Intel Enabled Server Acceleration Alliance AMD Server vendors Cisco Unified Computing System Dawning Dell Egenera Fujitsu HP Huawei IBM NEC Sun/Oracle Storage Systems, Volume Management and File Systems 3Par Compellent EMC VPLEX FalconStor Fusion-io Hitachi Data Systems HP Storage Array Systems Lustre Network Appliance OCFS2 PillarData Symantec Veritas Storage Foundation Networking: Switches, Host Bus Adapters (HBAs), Converged Network Adapters (CNAs), InfiniBand Brocade Emulex Mellanox QLogic Voltaire SOA and Middleware ActiveState ActivePerl, ActivePython Tibco Zend Backup, Recovery & Replication Arkeia Network Backup Suite BakBone NetVault CommVault Simpana 8 EMC Networker, Replication Manager FalconStor Continuous Data Protector HP Data Protector NetApp Snapmanager Quest LiteSpeed Engine Steeleye Data Replication, Disaster Recovery Symantec NetBackup, Veritas Volume Replicator, Symantec Backup Exec Zmanda Amanda Enterprise Data Center Automation BMC CA Unicenter HP Server Automation (formerly Opsware), System Management Homepage Oracle Enterprise Manager Ops Center Quest Vizioncore vFoglight Pro TeamQuest Manager Clustering & High Availability FUJITSU x10sure NEC Express Cluster X Steeleye Lifekeeper Symantec Cluster Server Univa UniCluster Virtualization Platforms and Cloud Providers Amazon EC2 Citrix XenServer Rackspace Cloud VirtualBox VMWare ESX Security Management ArcSight: Enterprise Security Manager, Logger CA Access Control Centrify Suite Ecora Auditor FoxT Manager Likewise: Unix Account Management Lumension Endpoint Management and Security Suite QualysGuard Suite Quest Privilege Manager McAfee Application Control, Change ControlIntegrity Monitor, Integrity Control, PCI Pro Solidcore S3 Symantec Enterprise Security Manager (ESM) Tripwire Trusted Computer Solutions

• Ask the Readers: Do You Use the Command Line?

  - by Asian Angel

  Most people have heard of it but not everyone is familiar or comfortable with how to use this bastion of geekdom. This week we would like to know if you use the command line or not. The command line…the bastion of ultimate geekery in many peoples’ eyes. You often hear people referring to doing things using the command line, so there must be something to it, right? For some people using the command line is the best, most efficient, and easiest way to do things on their systems. These are the people that many of us wish we were like. Next you have those who are proficient at using the command line but do not rely on it for everything they do on their systems. Then there are people who know how to perform some tasks or hacks using the command line but may not be as comfortable or knowledgeable as they wish to be using it. Moving on you find those who are interested in learning how to use the command line and just need a small push to get started.  Perhaps you feel too intimidated to learn it and just need the right opportunity to come along. And maybe you do not care one way or the other so long as you get done what you want to do on your system. Or you may prefer to simply use a graphical interface since that is quicker and easier for you (along with being familiar). You can find the whole range of people when it comes to using the command line… This week we would like to know if you use the command line or not. What command line category do you fit into? Power user? Casual usage? Totally lost? Let us know in the comments! How-To Geek Polls require Javascript. Please Click Here to View the Poll.

• Learn Cloud Computing – It’s Time

  - by Ben Griswold

  Last week, I gave an in-house presentation on cloud computing.  I walked through an overview of cloud computing – characteristics (on demand, elastic, fully managed by provider), why are we interested (virtualization, distributed computing, increased access to high-speed internet, weak economy), various types (public, private, virtual private cloud) and services models (IaaS, PaaS, SaaS.)  Though numerous providers have emerged in the cloud computing space, the presentation focused on Amazon, Google and Microsoft offerings and provided an overview of their platforms, costs, data tier technologies, management and security.  One of the biggest talking points was why developers should consider the cloud as part of their deployment strategy: You only have to pay for what you consume You will be well-positioned for one time event provisioning You will reap the benefits of automated growth and scalable technologies For the record: having deployed dozens of applications on various platforms over the years, pricing tends to be the biggest customer concern.  Yes, scalability is a customer consideration, too, but it comes in distant second.  Boy do I hope you’re still reading… You may be thinking, “Cloud computing is well and good and it sounds catchy, but should I bother?  After all, it’s just another technology bundle which I’m supposed to ramp up on because it’s the latest thing, right?”  Well, my clients used to be 100% reliant upon me to find adequate hosting for them.  Now I find they are often aware of cloud services and some come to me with the “possibility” that deploying to the cloud is the best solution for them.  It’s like the patient who walks into the doctor’s office with their diagnosis and treatment already in mind thanks to the handful of Internet searches they performed earlier that day.  You know what?  The customer may be correct about the cloud. It may be a perfect fit for their app.  But maybe not…  I don’t think there’s a need to learn about every technical thing under the sun, but if you are responsible for identifying hosting solutions for your customers, it is time to get up to speed on cloud computing and the various offerings (if you haven’t already.)  Here are a few references to get you going: DZone Refcardz #82 Getting Started with Cloud Computing by Daniel Rubio Wikipedia Cloud Computing – What is it? Amazon Machine Images (AMI) Google App Engine SDK Azure SDK EC2 Spot Pricing Google App Engine Team Blog Amazon EC2 Team Blog Microsoft Azure Team Blog Amazon EC2 – Cost Calculator Google App Engine – Cost and Billing Resources Microsoft Azure – Cost Calculator Larry Ellison has stated that cloud computing has been defined as "everything that we currently do" and that it will have no effect except to "change the wording on some of our ads" Oracle launches worldwide cloud-computing tour NoSQL Movement

• MySQL on Windows - Why, Where and How

  - by bertrand.matthelie(at)oracle.com

  @font-face { font-family: "Arial"; }@font-face { font-family: "Courier New"; }@font-face { font-family: "Wingdings"; }@font-face { font-family: "Cambria"; }p.MsoNormal, li.MsoNormal, div.MsoNormal { margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: "Times New Roman"; }a:link, span.MsoHyperlink { color: blue; text-decoration: underline; }a:visited, span.MsoHyperlinkFollowed { color: purple; text-decoration: underline; }div.Section1 { page: Section1; }ol { margin-bottom: 0cm; }ul { margin-bottom: 0cm; } Over the years Windows has become a major development and deployment platform for MySQL. As a matter of fact, Windows consistently ranks as the #1 development platform in our surveys, and now also ranks higher than any Linux distribution as a deployment platform among MySQL Community Edition users.   We've made various technical resources available in our MySQL on Windows Resource Center including articles, whitepapers and archived webinars. MySQL users are also sharing their experiences and writing how-to articles, and it's great to see former MySQL/Sun/Oracle employees still contributing! Thanks Anders for a recent step-by-step part 1 article on working with MySQL on Windows.   We also got feedback from customers wishing to get higher-level information about MySQL on Windows, to help them and others in their organizations better understand:   ·       Why is the world's most popular open source database so popular on Windows?   ·       What are the applications for which one should consider MySQL on Microsoft's platform?   ·       How should Windows shops relying on Microsoft databases get going with MySQL?   Those are the questions we aim to answer in our guide "MySQL on Windows - Why, Where and How", that you can download here.

• First time using Java Web Start in Ubuntu - Fatal Launch Exception

  - by MountainX

  I've been using Ubuntu for a while and Java Web Start applications have never "just worked" in the current or any prior version, so I ignored them until now. However, now I have a need to get them working in Firefox. When I am on a page like this: http://www.oracle.com/technetwork/java/demos-nojavascript-137100.html I want to be able to click on the demos as suggested and have them run.

• Announcing Oracle Enterprise Content Management Suite 11g

  - by [email protected]

  Today Oracle announced Oracle Enterprise Content Management Suite 11g. This is a major release for us, and reinforces our three key themes at Oracle: Complete New in this release - Oracle ECM Suite 11g is built on a single, unified repository. Every piece of content - documents, HTML pages, digital assets, scanned images - is stored and accessbile directly from the repository, whether you are working on websites, creating brand logos, processing accounts payable invoices, or running records and retention functions. It makes complete, end-to-end management of content possible, from the point it enters the organization, through its entire lifecycle. Also new in this release, the installation, access, monitoring and administration of Oracle ECM Suite 11g is centralized. As a complete system, organizations can lower the costs of training and usage by having a centralized source of information that is easily administered. As part of this new unified repository release, Oracle has released a benchmarking white paper that shows the extreme performance and scalability of Oracle ECM Suite. When tested on a two node UCM Server running on Sun Oracle DB Machine Half Rack Hardware with an Exadata storage server, Oracle ECM Suite 11g is able to ingest over 178 million documents per day. Open Oracle ECM Suite 11g is built on a service-oriented architecture. All functions are available through standards-based services calls in Web Services or Java. In this release Oracle unveils Open Web Content Management. Open Web Content Management is a revolutionary approach to web content management that decouples the content management process from the process of creating web applications. One piece of this approach is our one-click web content management. With one click, a web application builder can drag content services into their application, enabling their users to also edit content with just one click. Open Web Content Management is also open because it enables Web developers to add Web content management to new and existing JavaServer Pages (JSP), JavaServer Faces (JSF) and Oracle Application Development Framework (ADF) Faces applications Open content distribution - Oracle ECM Suite 11g offers flexible deployment options with a built-in smart cache so organizations can deliver Web sites or Web applications without requiring Oracle ECM Suite as part of the delivery system Integrated Oracle ECM Suite 11g also offers a series of next generation desktop integrations, providing integrations such as: New MS Office integration with menus to access managed content, insert managed links, and compare managed documents using standard MS Office reviewing tools Automatic identity tagging of documents on download - to help users understand which versions they are viewing and prevent duplicate content items in the content repository. New "smart productivity folders" to show a users workflow inbox, saved searches and checked out content directly from Windows Explorer Drag and drop metadata pop-ups Check in and check out for all file formats with any standard WebDAV server As part of Oracle's Enterprise Application Documents initiative, Oracle Content Management 11g also provides certified application integrations with solution templates You can read the press release here. You can see more assets at the launch center here. You can sign up for the announcement webinar and hear more about the new features here. You can read the benchmarking study here.

• Monitora&ccedil;&atilde;o com Oracle Enteprrise Manager

  - by fernando.galdino

  A figura abaixo oferece uma visão geral das possibilidades de monitoramento providas pelo Oracle Enterprise Manager (OEM), que é uma ferramenta que permite gerenciar a infraestrutura de TI da empresa. Um componente importante da solução é chanado OEM Grid Control. Esse componente permite gerenciar, visualizar e monitorar diversos elementos a partir de uma mesma console. E que elementos podem ser monitorados? No conceito utilizado pelo OEM, os elementos que podem ser monitorados são chamados de Targets, e esses targets envolvem a monitoração de hosts (Windows, Linux, Solaris), Banco de Dados, Middleware, Aplicações Web, Serviços que podem ser customizados pelo administrador, Sistemas e Grupos de targets, além dos aplicativos Oracle. Cada elemento monitorado é ativado através de packs de gerenciamento. Ou seja, há uma série de packs que podem ser adquiridas conforme a necessidade, para permitir a monitoração a partir do próprio OEM Grid Control. Existem packs de monitoramento especiais para banco de dados Oracle, packs de monitoramento para Tomcat, Jboss, WebLogic, SOA Suite, Identity Management. A lista é bem extensa e darei mais detalhes em um novo post. Mas caso queira visitar, veja: http://download.oracle.com/docs/cd/B16240_01/doc/nav/overview.htm Além das packs de monitoramento, existem também plugins e conectores. Os plugins permitem o gerenciamento de elementos adicionais, tais como dispositivos de rede, servidores, banco de dados de terceiros (DB2, SQL Server), Vmware, etc. Já os conectores permitem a integração com outros softwares, tais como gerenciadores de requisições de helpdesk, de modo a integrar os alertas gerados pela ferramenta e gerar tickets em ferramentas como CA Service Desk, BMC Remedy e outros. A extensão de funcionalidades é realmente bem vasta. Num próximo post irei comentar sobre o Ops Center, um novo componente que surgiu após a aquisição da Sun. Além do Grid Control e do Ops Center, há outros componentes bem interessantes. A figura abaixo ilustra diversas camadas onde o ferramental Oracle pode ser usado para monitoração. Há uma pack que permite gerenciar os níveis de serviços em todas as camadas ilustradas. Dada uma requisição, pode-se decompor os dados de SLA em cada camada. E há também o Real User Monitoring, que trata de medir a experiência com o usuário. Falarei disso num novo post, mas basicamente a ferramenta permite acompanhar todo o tráfego de rede gerado dos usuários finais até os servidores web, e com isso rastrear como cada usuário usa a aplicação, quanto tempo ele navega pelo site, se ele enfrentou algum tipo de problema, se houve algum pedido não finalizado devido a algum problema na infraestrutura. É uma ferramenta bem interessante, falarei um pouco mais dela depois. E claro, há também componentes para a realização de testes funcionais e de carga. Em breve, aqui no blog :)

• Eclipse has multiple issues after JRE-6 (OpenJDK) upgrade

  - by Eusebius

  I'm on 12.04 LTS, and trying to use Eclipse Indigo. This morning Ubuntu made me update the following packages: Preparing to replace icedtea-6-jre-cacao 6b24-1.11.3-1ubuntu0.12.04.1 (using .../icedtea-6-jre-cacao_6b24-1.11.4-1ubuntu0.12.04.1_amd64.deb) ...

Unpacking replacement openjdk-6-jre ... After that (but I cannot swear it is the root cause), I have the following issues in Eclipse: When trying to launch the simplest HelloWorld program (which behaves fine with manual javac/java), I get either nothing or: An internal error occurred during: "Launching HelloWorld". org/eclipse/jdt/debug/core/JDIDebugModel I get an "Error log" tab in the console panel, with an error: Could not create the view: An unexpected exception was thrown. (Follows a consequent NullPointerException stacktrace between sun.util.calendar.ZoneInfoFile.getZoneIDs(ZoneInfoFile.java:785) and org.eclipse.equinox.launcher.Main.main(Main.java:1386)) When trying to access the Installed JREs part of the preferences, I get a popup saying: Unable to create the selected preference page. An error occurred while automatically activating bundle org.eclipse.jdt.debug.ui (162). And the preference tab says An error has occurred when creating this preference page. Until today I had a manually installed Eclipse (one of the official bundles available on their site), I've tried to replace it by the repository version and I get the same errors. What should I do to make Eclipse work again? Another person reports: Same happened to me after updating last night. Already tried reinstalling Eclipse and Java, starting Eclipse with -clean and starting new workspace and new .eclipse dir, but nothing helps.

• Travelling MVP #3: Community event in Varna, Bulgaria

  - by DigiMortal

  Second stop in my DevReach 2012 trip was at Varna. We had not much time to hang around there but this problem will get fixed next year if not before. But still we had sessions there with Dimitar Georgijev and I had also chance to meet local techies. Next time we will have more tech and beers for sure! We started in the morning from Bucharest and travelled through Ruse, Razgrad and Shumen to Varna. It’s about 275km. We used cab, local bus and Dimitar father’s car. We had one food stop in Ruse and after that we went directly to Varna. Here is our route on map. Varna is Bulgarian city that locates on western coast of Black Sea. I have been there once before this trip and it’s good place to have vacation under sun. Also autumn is there milder than here in Estonia (third day of snow is going on). Bulgaria has some good beers, my favorite mankind killer called rakia and very good national cuisine. Food is made of fresh stuff and it is damn good experience. Here are some arbitrarily selected images (you can click on these to view at original size): Old bus “monument” in Razgrad Stuffed peppers, Bulgarian national cuisine Infra-red community having good time and beers We made our sessions at one study class of Varna technical university. It’s a little bit old style university but everything we needed was there and we had no problems with machinery. Sessions were same as in Bucharest. The user group in Varna is brand new and hopefully it will be something bigger one good day. At least I try to make my commits so they get on their feet quicker. As we had not much time to announce the event there was about 15 guys listening to us and I’m happy that it was not too much hyped event because still I was getting my first experiences with foreign audiences. After sessions we took our stuff to hotel and went to hang around with local techies. We had some good time there and made some new friends. Next time when I go to Varna I go back as more experienced speaker and I plan to do there one tougher and highly challenging session. Maybe somebody from Estonian community will join me and then it will be well planned surprise-attack to Varna :)

• Back-sliding into Unmanaged Code

  - by Laila

  It is difficult to write about Microsoft's ambivalence to .NET without mentioning clichés about dog food.  In case you've been away a long time, you'll remember that Microsoft surprised everyone with the speed and energy with which it introduced and evangelised the .NET Framework for managed code. There was good reason for this. Once it became obvious to all that it had sleepwalked into third place as a provider of development languages, behind Borland and Sun, it reacted quickly to attract the best talent in the industry to produce a windows version of the Java runtime, with Bounds-checking, Automatic Garbage collection, structures exception handling and common data types. To develop applications for this managed runtime, it produced several excellent languages, and more are being provided. The only thing Microsoft ever got wrong was to give it a stupid name. The logical step for Microsoft would be to base the entire operating system on the .NET framework, and to re-engineer its own applications. In 2002, Bill Gates, then Microsoft Chairman and Chief Software Architect said about their plans for .NET, "This is a long-term approach. These things don't happen overnight." Now, eight years later, we're still waiting for signs of the 'long-term approach'. Microsoft's vision of an entirely managed operating system has subsided since the Vista fiasco, but stays alive yet dormant as Midori, still being developed by Microsoft Research. This is an Internet-centric fork of the singularity operating system, a research project started in 2003 to build a highly-dependable operating system in which the kernel, device drivers, and applications are all written in managed code. Midori is predicated on the prevalence of connected systems, with provisions for distributed concurrency where application components exist 'in the cloud', and supports a programming model that can tolerate cancellation, intermittent connectivity and latency. It features an entirely new security model that sandboxes applications for increased security. So have Microsoft converted its existing applications to the .NET framework? It seems not. What Windows applications can run on Mono? Very few, it seems. We all thought that .NET spelt the end of DLL Hell and the need for COM interop, but it looks as if Bill Gates' idea of 'not overnight' might stretch to a decade or more. The Operating System has shown only minimal signs of migrating to .NET. Even where the use of .NET has come to dominate, when used for server applications with IIS, IIS itself is still entirely developed in unmanaged code. This is an irritation to Microsoft's greatest supporters who committed themselves fully to the NET framework, only to find parts of the Ambivalent Microsoft Empire quietly backsliding into unmanaged code and the awful C++. It is a strategic mistake that the invigorated Apple didn't make with the Mac OS X Architecture. Cheers, Laila

• Ed Burns' Servlet 4/HTTP 2 Session at JavaOne 2014

  - by reza_rahman

  For the Java EE track at JavaOne 2014 we are highlighting some key sessions and speakers to better inform you of what you can expect, right up until the start of the conference. To this end we recently interviewed Ed Burns. Ed is a veteran of Sun and now Oracle. He has been and is instrumental in pushing the JSF ecosystem forward as specification lead. Besides his specification lead work Ed is well regarded as an author and speaker on his own right. In addition to carrying the JSF torch Ed will be co-leading the key Servlet 4 specification for Java EE 8, along with Servlet specification guru Shing Wai Chan. The primary goal of Servlet 4 is to enable the fundamentally important changes in HTTP 2 for the entire server-side Java ecosystem. We wanted to talk to Ed about his Servlet 4 session at JavaOne 2014 and HTTP 2 generally: The details for the Servlet 4 session can be found here. Ed has several other key sessions on the track that we hope to talk to him about separately in the near future: What’s Next for JSF?: In this key session, Ed will be sharing the next steps for the continued evolution of the JSF specification in Java EE 8. Where’s My UI? The 2014 JavaOne Web App UI Smackdown: The UI space for web applications, especially in the Java ecosystem continues to be as hotly contested as ever. This is especially true with the (re)introduction of JavaScript based rich client frameworks like AngularJS. This lively panel brings together experts representing the diverse schools of thought for web UIs. Ed will be representing JSF of course. Neal Ford will moderate the panel as an independent and hopefully reasonably neutral party. Adopt-a-JSR for Java EE 7 and Java EE 8: Adopt-a-JSR has been a reasonable success for Java EE 7. With Java EE 8 we are planning to strengthen it far more as away of getting grassroots level participation in the specification efforts. This session will introduce Adopt-a-JSR, share how it worked for Java EE 7 and what we plan to do with it in Java EE 8. Ed will be sharing his perspectives on Adopt-a-JSR for both Java EE 7 and Java EE 8. Besides Ed's sessions, we have a very strong program for the Java EE track and JavaOne overall - just explore the content catalog. If you can't make it, you can be assured that we will make key content available after the conference just as we have always done.

• Atmospheric scattering sky from space artifacts

  - by ollipekka

  I am in the process of implementing atmospheric scattering of a planets from space. I have been using Sean O'Neil's shaders from http://http.developer.nvidia.com/GPUGems2/gpugems2_chapter16.html as a starting point. I have pretty much the same problem related to fCameraAngle except with SkyFromSpace shader as opposed to GroundFromSpace shader as here: http://www.gamedev.net/topic/621187-sean-oneils-atmospheric-scattering/ I get strange artifacts with sky from space shader when not using fCameraAngle = 1 in the inner loop. What is the cause of these artifacts? The artifacts disappear when fCameraAngle is limtied to 1. I also seem to lack the hue that is present in O'Neil's sandbox (http://sponeil.net/downloads.htm) Camera position X=0, Y=0, Z=500. GroundFromSpace on the left, SkyFromSpace on the right. Camera position X=500, Y=500, Z=500. GroundFromSpace on the left, SkyFromSpace on the right. I've found that the camera angle seems to handled very differently depending the source: In the original shaders the camera angle in SkyFromSpaceShader is calculated as: float fCameraAngle = dot(v3Ray, v3SamplePoint) / fHeight; Whereas in ground from space shader the camera angle is calculated as: float fCameraAngle = dot(-v3Ray, v3Pos) / length(v3Pos); However, various sources online tinker with negating the ray. Why is this? Here is a C# Windows.Forms project that demonstrates the problem and that I've used to generate the images: https://github.com/ollipekka/AtmosphericScatteringTest/ Update: I have found out from the ScatterCPU project found on O'Neil's site that the camera ray is negated when the camera is above the point being shaded so that the scattering is calculated from point to the camera. Changing the ray direction indeed does remove artifacts, but introduces other problems as illustrated here: Furthermore, in the ScatterCPU project, O'Neil guards against situations where optical depth for light is less than zero: float fLightDepth = Scale(fLightAngle, fScaleDepth); if (fLightDepth < float.Epsilon) { continue; } As pointed out in the comments, along with these new artifacts this still leaves the question, what is wrong with the images where camera is positioned at 500, 500, 500? It feels like the halo is focused on completely wrong part of the planet. One would expect that the light would be closer to the spot where the sun should hits the planet, rather than where it changes from day to night. The github project has been updated to reflect changes in this update.
