OpenCloth: A collection of source codes implementing cloth simulation algorithms in OpenGL

Introducing an OpenGL based cloth simulation code base. We implement all of the existing cloth simulation algorithms in as simplistic an approach as possible so that learners may know exactly what is needed to get a cloth simulation system up and running in OpenGL with a minimum of fuss. OpenCloth project has been initiated with a view that it may help beginners and researchers alike to implement the basic algothims for cloth simulation using OpenGL API. It is not intended as another library that you can plugin into your game engine directly. Rather, you can learn from it and then implement a technique or two in you own game/physics engine. With a little bit of effort, it should be straight forward to implement the discussed algorithms on other platforms and Graphics API. Focus is on how to handle the bare minimum required to implement the techniques. Rather than wrapping code into classes, we implement the whole code in a single source file.

Version 0.9.8 of the free open-source 3D engine PixelLight released

The version 0.9.8 of the free open-source, cross-platform 3D application framework PixelLight has been released. It’s been one year since the first public release and nearly 9 years since development start on September 16, 2002. The technology is using OpenGL as well as GLSL within it’s primary renderer. Applications, including their life cycle, are now controlled by frontends. The SDK includes four frontends: One for PixelLight’s own GUI system, a lightweight native OS frontend, one for the UI framework Qt and a null frontend without any GUI involved used for example when only rendering into background buffers.

Efficient multi-fragment rendering using d-buffer - an OpenGL 4.2 use case

Drawing effects that need to store multiple data elements per-pixel is not an easy task, when you consider an architecture as rigid as highly parallel GPU subsystem. It is even more so, when you want to put irregular number of data elements (e.g. fragments) per-pixel. Current methods often suffer from the low performance pitfalls of non-regular memory references. See how d-buffer storage scheme can help composing your multiple, irregular in terms of per-pixel count fragments into hardware friendly regular data structure. All with the help of GL_ARB_shader_image_load_store, GL_ARB_shader_atomic_counters or simply core OpenGL 4.2.

Starting a new series of tutorials about OpenGL Shaders

From the creator of the series “All About OpenGL ES 2” and author of NinevehGL Engine (Free 3D engine for iOS), arrives a new tutorial about OpenGL Shaders. This is the first of three and brings the basic concepts about shaders for beginners, treating concepts like Normals and Tangent Space, differences between per-vertex and per-fragment lights and explaining in-depth what the shaders are. The next tutorials of this series will show how to calculate the complex lights, reflections, bump mapping and more.

Mesa 7.11 gets much closer to supporting OpenGL 3

Version 7.11 of free and opensource OpenGL implementation gets very close to meet OpenGL 3.0 requirements, but there is still work to be done in bringing up GLSL 1.30 support, depth format cube textures, GLX_ARB_create_context, and various other features. Mature Intel Sandy Bridge and preliminary support for Ivy bridge has been added. AMD Llano Fusion graphics and Radeon HD 6900 “Cayman” are now supported.
