In March, 2010, the Khronos group approved an extension to add timers to OpenGL. The version was 3.2. As of OpenGL 3.3 this functionality has become part of the specification. As mention in the Very Simple Profile Library page, profiling is an essential technique to truly understand how to improve the performance of an application. … Read more
VSPL new version. Added more timer options. Users can now select between the standard C clock function, Unix gettimeofday, Windows high performance timer, with QueryPerformanceCounter or system time, using GetSystemTime.
A Siggraph 2010 course “There are strong indications that the future of interactive graphics programming is a model more flexible than today’s OpenGL/Direct3D pipelines. As such, graphics developers need to have a basic understanding of how to combine emerging parallel programming techniques and more flexible graphics processors with the traditional interactive rendering pipeline. The first … Read more
Ray Wenderlich’ssite has posted an OpenGL ES 2.0 for iPhone Tutorial for beginners. It starts from scratch, describing how to setup a project and goes all the way till drawing a 3D rotating cube.
Optimization is a must in computer graphics applications, mainly in those devoted to real-time interaction, such as visualization and games. One possibility is to optimise everything that can be optimised, but this is in most cases a waste of time. There are segments in our applications that when optimised bring an overall gain in efficiency … Read more
Patrick Cozzi and Christophe Riccio are calling for proposals for a new book, Game Programming Gems style, but dedicated to OpenGL, GL ES, and Web GL, i.e. to the GL world. The site for the CFP contains a list of possible themes for contributions. The deadline for proposals is the 15th of August.
VSFL has suffered a minor update to be able to render fixed size fonts such as Courier New. Previously all chars would have the optimal length, but this makes formatted printing difficult in some circumstances. A new parameter has been added to the loadFont method to specify if the font is to be rendered with … Read more
G-Truc Creation has been building a samples pack for OpenGL that covers versions from 2.1 up to 4.1 This latest release has reached the 100 samples mark. An invaluable source of code for the newest versions.
Very Simple Font Library – Text rendering is very useful to display information on top of a 3D world. VSFL aims at providing users with the ability to render bitmapped text in an OpenGL application using the core profile. With immediate mode gone in core OpenGL versions, so are the vast majority of font libs … Read more
The Very Simple Matrix Library (VSML) header file has been updated to include comments suitable for Doxygen. Some bugs on the frustum and ortho functions were also cleared. I’ve also installed a plug-in for some nice syntax highlight which I hope it makes code reading easier. If you find any other bugs please let me … Read more
