  • Where to start learning OpenGL with C++?

    - by NERDcustard
    I'm 16 years old and my name is Norbert. I have learnt C++ and made some cool text based games and such but I would love to start graphic's programming. I'm a decent artiest (I will have some of my work bellow) I know the base of C++ but I really would like to get into OpenGL. I need someone to show me some good tutorials for OpenGl with C++ so I can really get into game dev. My goal is to be able to program a simple 2d game by the end of the year and I have lots of time to do so. I'm en-rolled in a game dev next year and really need some help with starting off. http://imgur.com/QZjKX http://imgur.com/3CZy7

  • Where should you put constants and why?

    - by Tim Meyer
    In our mostly large applications, we usually have a only few locations for constants: One class for GUI and internal contstants (Tab Page titles, Group Box titles, calculation factors, enumerations) One class for database tables and columns (this part is generated code) plus readable names for them (manually assigned) One class for application messages (logging, message boxes etc) The constants are usually separated into different structs in those classes. In our C++ applications, the constants are only defined in the .h file and the values are assigned in the .cpp file. One of the advantages is that all strings etc are in one central place and everybody knows where to find them when something must be changed. This is especially something project managers seem to like as people come and go and this way everybody can change such trivial things without having to dig into the application's structure. Also, you can easily change the title of similar Group Boxes / Tab Pages etc at once. Another aspect is that you can just print that class and give it to a non-programmer who can check if the captions are intuitive, and if messages to the user are too detailed or too confusing etc. However, I see certain disadvantages: Every single class is tightly coupled to the constants classes Adding/Removing/Renaming/Moving a constant requires recompilation of at least 90% of the application (Note: Changing the value doesn't, at least for C++). In one of our C++ projects with 1500 classes, this means around 7 minutes of compilation time (using precompiled headers; without them it's around 50 minutes) plus around 10 minutes of linking against certain static libraries. Building a speed optimized release through the Visual Studio Compiler takes up to 3 hours. I don't know if the huge amount of class relations is the source but it might as well be. You get driven into temporarily hard-coding strings straight into code because you want to test something very quickly and don't want to wait 15 minutes just for that test (and probably every subsequent one). Everybody knows what happens to the "I will fix that later"-thoughts. Reusing a class in another project isn't always that easy (mainly due to other tight couplings, but the constants handling doesn't make it easier.) Where would you store constants like that? Also what arguments would you bring in order to convince your project manager that there are better concepts which also comply with the advantages listed above? Feel free to give a C++-specific or independent answer. PS: I know this question is kind of subjective but I honestly don't know of any better place than this site for this kind of question. Update on this project I have news on the compile time thing: Following Caleb's and gbjbaanb's posts, I split my constants file into several other files when I had time. I also eventually split my project into several libraries which was now possible much easier. Compiling this in release mode showed that the auto-generated file which contains the database definitions (table, column names and more - more than 8000 symbols) and builds up certain hashes caused the huge compile times in release mode. Deactivating MSVC's optimizer for the library which contains the DB constants now allowed us to reduce the total compile time of your Project (several applications) in release mode from up to 8 hours to less than one hour! We have yet to find out why MSVC has such a hard time optimizing these files, but for now this change relieves a lot of pressure as we no longer have to rely on nightly builds only. That fact - and other benefits, such as less tight coupling, better reuseability etc - also showed that spending time splitting up the "constants" wasn't such a bad idea after all ;-)

  • The practical cost of swapping effects

    - by sebf
    Hello, I use XNA for my projects and on those forums I sometimes see references to the fact that swapping an effect for a mesh has a relatively high cost, which surprises me as I thought to swap an effect was simply a case of copying the replacement shader program to the GPU along with appropriate parameters. I wondered if someone could explain exactly what is costly about this process? And put, if possible, 'relatively' into context? For example say I wanted to use a short shader to help with picking, I would: Change the effect on every object, calculting a unique color to identify it and providing it to the shader. Draw all the objects to a render target in memory. Get the color from the target and use it to look up the selected object. What portion of the total time taken to complete that process would be spent swapping the shaders? My instincts would say that rendering the scene again, no matter how simple the shader, would be an order of magnitude slower than any other part of the process so why all the concern over effects?

  • Are there any good programs to learn Dvorak

    - by Alvar
    Hi, How do I learn Dvorak typing in Ubuntu? I have Ubuntu 10.04 and I'm planning to learn one of the Swedish dvorak versions. It's included in ubuntu 10.04. I used to play a game called Grand Prix Tycoon on mousebreaker.com . I know it's a silly game but if you use a game of some sort you can get better so much faster. A) Is there a program that I can use to learn Dvorak? B) Is there a game of some sort to learn Dvorak? C) Is the Swedish version I linked to supported?

  • Best place to install apps

    - by t3ch
    I am completely new to Ubuntu and I must say AskUbuntu and you folks are of great help. So now when I have started installing and playing with apps, my question is what is the best place to install/download apps? Like in Windows it usually goes under your C: drive and then you manage it under Program Files. Linux structure is quite different with a different folder hierarchy. I have attached the directory structure of my machine as well. I thought this question would help lot of beginners.

  • Webmaster Tools word count

    - by Henrik Erlandsson
    Is there a way to somehow verify that the googlebot finds the headings and the content, for example by word count? I'm asking this because I tried a program called Screaming Frog, which fails to even fetch the first h1 on a validated page - for about 1/3 of all the pages(!) - and got insecure. Even though the site looks hunky dory in Webmaster Tools, I'd like to know what a googlebot-like content crawler finds on my page and in what order. Any tips on such tools is appreciated. This is not about keyword count.

  • Taking HRMS to the Cloud to Simplify Human Resources Management

    - by HCM-Oracle
    By Anke Mogannam With human capital management (HCM) a top-of-mind issue for executives in every industry, human resources (HR) organizations are poised to have their day in the sun—proving not just their administrative worth but their strategic value as well.  To make good on that promise, however, HR must modernize. Indeed, if HR is to act as an agent of change—providing the swift reallocation of employees  and the rapid absorption of employee data required for enterprises to shift course on a dime—it must first deal with the disruptive change at its own front door. And increasingly, that means choosing the right technology and human resources management system (HRMS) for managing the entire employee lifecycle. Unfortunately, for most organizations, this task has proved easier said than done. This is because while much has been written about advances in HRMS technology, until recently, most of those advances took the form of disparate on-premises solutions designed to serve very specific purposes. Although this may have resulted in key competencies in certain areas, it also meant that processes for core HR functions like payroll and benefits were being carried out in separate systems from those used for talent management, workforce optimization, training, and so on. With no integration—and no single system of record—processes were disconnected, ease of use was impeded, user experience was diminished, and vital data was left untapped.  Today, however, that scenario has begun to change, and end-to-end cloud-based HCM solutions have moved from wished-for innovations to real-life solutions. Why, then, have HR organizations been so slow in adopting them? The answer—it would seem—is, “It’s complicated.” So complicated, in fact, that 45 percent of the respondents to PwC’s “Annual HR Technology Survey” (for 2013) reported having no formal HR software roadmap, and 40 percent stated that they “did not know” whether their organizations would be increasing their use of cloud or software as a service (SaaS) for HR.  Clearly, HR organizations need help sorting through the morass of HR software options confronting them. But just as clearly, there’s an enormous opportunity awaiting those that do. The trick will come in charting a course that allows HR to leverage existing technology while investing in the cloud-based solutions that will deliver the end-to-end processes, easy-to-understand analytics, and superior adaptability required to simplify—and add value to—every aspect of employee management. The Opportunity therefore is to cut costs, drive Innovation, and increase engagement by moving to cloud-based HCM.  Then you will benefit from one Interface, leverage many access points, and  gain at-a-glance insight across your entire workforce. With many legacy on-premises HR systems not being efficient anymore and cloud-based, integrated systems that span the range of HR functions finally reaching maturity, the time is ripe for moving core HR to the cloud. Indeed, for the first time ever there are more HRMS replacement initiatives than HRMS upgrade initiatives under way, and the majority of them involve moving to the cloud per Cedar Crestone’s 2013-2014 HRMS survey. To learn how you can launch your own cloud HCM initiative and begin using HR to power the enterprise, visit Oracle HRMS in the Cloud and Oracle’s new customer 2 cloud program.

  • What exactly can shaders be used for?

    - by Bane
    I'm not really a 3D person, and I've only used shaders a little in some Three.js examples, and so far I've got an impression that they are only being used for the graphical part of the equation. Although, the (quite cryptic) Wikipedia article and some other sources lead me to believe that they can be used for more than just graphical effects, ie, to program the GPU (Wikipedia). So, the GPU is still a processor, right? With a larger and a different instruction set for easier and faster vector manipulation, but still a processor. Can I use shaders to make regular programs (provided I've got access to the video memory, which is probable)? Edit: regular programs == "Applications", ie create windows/console programs, or at least have some way of drawing things on the screen, maybe even taking user input.

  • What are my tool options to prototype a 2D online multiplayer game?

    - by Asher Einhorn
    I'm looking for the best tool to allow me to quickly put together a 2D game that relies largely on networking. It's extremely likely that this game will require a server side program to constantly run. I have little experience with these things and since it's a prototype i'd like the easiest options for achieving this. I am looking to make this game for the web and mobile devices, although at present I only have access to ios hardware, (no android etc). I just want to get the bare bones of this set up so I can test it from the earliest opportunity to see if it's fun. EDIT - doesn't unity have some inbuilt networking stuff in it?

  • My Generation Drivers DropdownList Empty

    - by hmloo
    I just installed MyGeneration 1.3.1 on my Windows Vista, and when I try to setup the default settings there are no drivers to select from. but it's OK in my Windows XP machine. At last I got the answers from search engine, it is caused by multi .Net Frameworks coexist and MyMeta.dll is registered by the .Net v2.0 while it should be registered with the .Net v4.0. So we have to manually register the dll. Please follow these steps: 1. Run Visual Studio Command Prompt (2010) with "Run as Administrator". 2. Enter the command "regasm.exe "C:\Program Files\MyGeneration13\MyMeta.dll" /tlb: MyMeta.tlb" 3. Exit Command Prompt when successfully registered. 4. Run MyGeneration and the proplem should be disapear. Hope this helps. Thanks for reading.

  • Cannot execute binary file

    - by user291727
    I am new to Ubuntu and I'm trying to install Popcorn Time. I downloaded 32 bit version and tried to install it but that's where the problem started showing. I duble clicked the executable file and well, nothing happened. It's a official download from their web-site but it doesn't work. Maybe I'm doing something wrong.....Anyway, I found out that you can insatll it from a script, but people keep talking in ubuntu terms and I don't understand it, so I have a few questions: 1.How to make a script? (witch I'm suppose to run in terminal using bash comand), 2.Is it normal that i cannot run the installer, and if that is an installer or just files for the program. 3.If it is an installer, how do I make it work? 4.What does " Cannot execute binary file" mean? Thank you in advance, hope I'm not asking too many questions(please understand that I'm new to ubuntu) and sorry about my English. xD

  • Where do my programs get installed?

    Coming from windows I'm used to having everything installed in c:\program files\company\product. On Ubuntu I'm totally stumped. It seems like everything I install winds up somewhere different. Somethings are in /bin some in /home/myuser and others in /etc or /usr. I can't seem to figure this out. In particular I'm trying to find where they're located so I can either setup shortcuts on the task bar or associate them with other programs (like my greasemonkey editor) but I'm not having any luck.
