  • How to tile multiple procedurally generated textures?

    - by Burhuc
    I'm trying to develop a procedural tile generator for a game, mostly for the ground tiles, instead of using "hand-drawn" tiles. To achieve this I'm using Perlin noise and a sine wave with multiple parameters, which already gives me pretty nice results. I don't want to generate 1 tile and repeat that one forever for one ground type, but I want to avoid recurrences, so I'm generating n different tiles. The problem I'm having now is that I want to tile the generated textures (smooth transitions). At the moment I have this: 4 256x256 textures. I thought a simple method would be to just add the positions of the different tiles to the noise generation algorithm, so that, when creating the 4 256x256 textures, it would behave like it would create a 512x512 texture, but that somehow didn't work as intented. So how can I tile those textures?

  • Nokia aurait abandonné le développement de son Smartphone sous MeeGo et aurait opté pour Windows Phone 7

    Nokia aurait abandonné le développement de son Smartphone sous MeeGo et se serait allié à Microsoft Les rumeurs ne font que s'enchainer sur le net concernant l'avenir de l'OS mobile de Nokia MeeGo depuis la publication d'un memo interne expédié à tous les employés de la firme par son PDG Stephen Elop. Dans ce memo le PDG de Nokia fait une comparaison extrême en présentant sa firme comme étant une entreprise sur une plate-forme pétrolière en flamme, avant de conclure que des changements radicaux de comportements doivent être effectués. Elop fait un constat plutôt mitigé de la situation actuelle : « La première génération d'iPhone est sortie en 2007, et nous n'avons ...

  • Do search engines crawl PDFs and if so are there any rules to follow when making them

    - by RandomBen
    The website I am working on has a few hundred PDFs in it. I don't think I have ever seen any of them come back in a search but there are linked to directly from out site. They are also full of keywords because they are product documents. Is there anything special we need to do to get Google or other search engines to crawl them? Is there any hard and fast rules for making PDFs to help Google like them more? For instance should I run them through ghostscript to clean up broken PDF tags that Adobe creates during generation?

  • Ubuntu Freezes w/ Proxy

    - by jrc03c
    Ubuntu 11.04 freezes completely after a little while when using a proxy. It's fine when it's got a direct Internet connection, but it completely grinds to a halt after about 10 or 15 minutes of traffic through a proxy. Any ideas? UPDATE: Here's some more information. I have a second-generation MacBook, which has both OSX 10.6.8 (Snow Leopard) and Ubuntu 11.04 (Natty Narwhal) installed on it. When running through a proxy, Snow Leopard works fine, but Ubuntu freezes frequently. Any suggestions at all? Or, rather, what other kinds of information do you need?

  • Why googling by keycaptcha gives results on reCAPTCHA? [closed]

    - by vgv8
    EDIT: I'd like to change this title to: How to STOP Google's manipulation of Google search engine presented to general public? I am frequently googling and more and more frequently bump when searching by one software product I am given instead the results on Google's own products. For ex., if I google by keyword keycaptcha for the "Past 24 hours" (after clicking on "Show search tools" -- "Past 24 hours" on the left sidebar of a browser) I am getting the Google's search results show only results on reCAPTCHA. Image uploaded later: Though, if confine keycaptcha in quotes the results are "correct" (well, kind of since they are still distorted in comparison with other search engines). I checked this during few months from different domains at different ISPs, different operating systems and from a dozen of browsers. The results are the same. Why is it and how can it be possibly corrected? My related posts: "How Gmail spam filter works?" IP adresses blacklisting Update: It is impossible for me to directly start using google.com as I am always redirected to google.ru (from google.com) by my ip-address "auto-detect location" google's "convenience". The google's help tells that it is impossible to switch off my location auto-detection because it is very helpful feature. There is a work-around to use google.com/ncr (to get google.com) (?anybody know what does it mean) to prevent redirection from google.com but even. But all results are exactly the same OK, I can search by quoted "keycaptcha", I am already accustomed to these google's quirks, but the question arises why the heck to burn time promoting someone's product if GOOGLE uses other product brands for showing its own interests/brands (reCAPTCHA) instead and what can be done with it? The general user will not understand that he was cheated and just will pick up the first (wrong) results Update2: Note that this googling behaviour: is independent on whether I am logged-in (or log-out-ed of) a google account, which account, on browser (I tried Opera, Chrome, FireFox, IE of different versions, Safari), OS or even domain; there are many such cases but I just targeted one concrete restricted example speciffically to to prevent wandering between unrelated details and peculiarities; @Michael, first it is not true and this text contains 2 links for real and significant results.. I also wrote that this is just one concrete example from many and based on many-month exp. These distortions happen upon clicking on: Past 24 hours, Past week, Past month, Past year in many other keywords, occasions/configurations of searches, etc. Second, the absence of the results is the result and there is no point to sneakingly substitute it by another unsolicited one. It is the definition of spam and scam. 3d, the question is not abt workarounds like how to write search queries or use another searching engines. The question is how to straighten the googling's results in order to stop disorienting general public about. Update: I could not understand: nobody reproduces the described by me behavior (i.e. when I click "Past 24 hours" link in google search searching for keycaptcha, the presented results are only on reCAPTCHA presented)? Update: And for the "Past week":

  • Cocos2D: Upgrading from OpenGL 1.1 to 2.0

    - by Alex
    I have recently starting upgrading my ios game to the latest Cocos2D (2.0 rc), and I am having some difficulties upgrading my texture generation code to OpenGL 2.0. In the old version I generated images with this code: CCRenderTexture *rt = [CCRenderTexture renderTextureWithWidth:WIDTH height:HEIGHT]; [rt beginWithClear:bgColor.r g:bgColor.g b:bgColor.b a:bgColor.a]; glDisable(GL_TEXTURE_2D); glDisableClientState(GL_TEXTURE_COORD_ARRAY); glVertexPointer(2, GL_FLOAT, 0, verts); glColorPointer(4, GL_FLOAT, 0, colors); glDrawArrays(GL_TRIANGLE_STRIP, 0, (GLsizei)nVerts); glEnableClientState(GL_TEXTURE_COORD_ARRAY); glEnable(GL_TEXTURE_2D); [rt end]; But since OpenGL 2.0 works differently this code won't work. What is the best way to use the new OpenGL?

  • What are some non-MS languages that can write xlsx (Excel 2007+) documents efficiently?

    - by Honus Wagner
    Unfortunately, Excel format is required for the project I am working on. I have no problems getting the data I need in objects and arrays, and currently PHPExcel is doing handling the document generation. It works, but it's slow and loopy. Was wondering if there is a more efficient server language to generate Excel documents (not CSVs). This is a pure Linux environment so I need to stay away from .NET. I am open to any programming language that does it cleanly and efficiently. Thanks.

  • Will Apple abandon OpenCL?

    - by John
    I am developing OpenCL applications, amongst others for MacOS. The new Macbook pro 13 inch comes with an Intel HD Graphics 3000 card so it seams reasonable to assume all their mainstream computers like Macbook and Mac mini will also come out with this Intel graphics card soon. OpenCL is not available for Intel graphics cards. Intel having a terrible reputation in developing graphics drivers and Apple knowing this makes me wonder Apple is abandoning OpenCL already again. Especially considering OpenCL should run anywhere, not only on high end systems. Developing applications only for the high end Macs with dedicated graphics hardware or for previous generation hardware with the Geforce 320M would not be a feasible option for me. Does anybody have any thoughts on this?

    When I was using Windows 7 my notebook temperature was very good, it stayed very cool. After I installed 12.04, my notebook base is hot all the time, I cannot even put my hands on it for a long time. My notebook has a 2nd generation Intel i5 processor. I installed Jupiter and it shows 72 Degrees Celsius constantly. Anyone got a fix for this? I don't want to go back to windows but if I do not find any solution I will have to do it. I'd be very grateful for any help.

  • Advice Required Regarding Creating a Self Learning, Self Organizing Programming Team....

    - by tGilani
    Hello I'm a senior student at my university and chairperson of IEEE Student Branch there. Recently I was thinking of some idea to acquaint students with the professional environment, how software is produced in the industry and get a practical experience.. Obviously trips to software houses are not enough and we cannot provide this many internships. So the idea of simulating a software house within the university popped in. Resources at my disposal are students with their own laptops, university UPS and lan network with internet access, and a reasonably sized room with a whiteboard and three hours free time daily.. :) However, I have absolutely no idea where to begin with. Milestones or whatever it may be called, are Requirements Document generation, sharing of resources, delegation of tasks, version controlling etc... I'd really appreciate some advice, programming tools (for JAVA), communication tools etc and other things used in a decent software house... Technologies to be targeted shall be random possibly starting with J2EE Spring Hibernate and Later Visual Programming in .NET C# and ASP.NET MVC as well as Android or iPhone development....

  • Earliest use of Comments as Semantically Meaningful Things in a Program?

    - by Alan Storm
    In certain corners of the PHP meta-programming world, it's become fashionable to use PHPDoc comments as a mechanism for providing semantically meaningful information to a program. That is, other code will parse the doc blocks and do something significant with the information encoded in those comments. Doctrine's annotations and code generation are an example of this. What's the earliest (or some early) use of this technique? I have vague memories of some early java Design by Contract implementations doing similar things, but I'm not sure of those folks were inventing the technique, or if they got it from somewhere. Mainly asking so I can provide some historical context for PHP developers who haven't come across the technique before, and are distrustful of it because it seems a little crazy pants.

  • Type Conversion in JPA 2.1

    - by delabassee
    The Java Persistence 2.1 specification (JSR 338) adds support for various new features such as schema generation, stored procedure invocation, use of entity graphs in queries and find operations, unsynchronized persistence contexts, injection into entity listener classes, etc. JPA 2.1 also add support for Type Conversion methods, sometime called Type Converter. This new facility let developers specify methods to convert between the entity attribute representation and the database representation for attributes of basic types. For additional details on Type Conversion, you can check the JSR 338 Specification and its corresponding JPA 2.1 Javadocs. In addition, you can also check those 2 articles. The first article ('How to implement a Type Converter') gives a short overview on Type Conversion while the second article ('How to use a JPA Type Converter to encrypt your data') implements a simple use-case (encrypting data) to illustrate Type Conversion. Mission critical applications would probably rely on transparent database encryption facilities provided by the database but that's not the point here, this use-case is easy enough to illustrate JPA 2.1 Type Conversion.

  • How to generate "language-safe" UUIDs?

    - by HappyDeveloper
    I always wanted to use randomly generated strings for my resources' IDs, so I could have shorter URLs like this: /user/4jz0k1 But I never did, because I was worried about the random string generation creating actual words, eg: /user/f*cker. This brings two problems: it might be confusing or even offensive for users, and it could mess with the SEO too. Then I thought all I had to do was to set up a fixed pattern like adding a number every 2 letters. I was very happy with my 'generate_safe_uuid' method, but then I realized it was only better for SEO, and worse for users, because it increased the ratio of actual words being generated, eg: /user/g4yd1ck5 Now I'm thinking I could create a method 'replace_numbers_with_letters', and check that it haven't formed any words against a dictionary or something. Any other ideas? ps. As I write this, I also realized that checking for words in more than one language (eg: english and french, spanish, etc) would be a mess, and I'm starting to love numbers-only IDs again.

  • Most efficient way to generate 2D portraits

    - by user1221
    Hey, I am not sure if this is a fitting question for gamedev, or if it is too art related. I am currently trying, to create 2D character protraits for my game. At first I tried to draw them and even though it helped polishing my drawing skills the end result either required way too much time or it simply looked like it was created by a grade school kid. So I am currently looking into some tools which from which people like me who are not out of the art-world might benefit. Especially tools which can create a 3D head+hair, so that I can render them. I have tried several 3D generation tools such as makehead and makehuman to create the basic head-shape. But I have to admit I am not well versed in what other options are available/what has the best quality/etc.
