On the lab systems however, we generally see no textures, or just the last texture loaded in glBindTexture (actually using QT's bind texture, but I tried replacing it with the related OpenGL ...

IntroductionThis article discusses why using a texture rather than an image can improve OpenGL rendering performance. It is accompanied by a simple C++ application that alternates between using a ...

Best part is you can use a 2d greyscale texture as an altitude-gradient map ( where altitude is y and gradient is x, and the p coord ( 0->1 ) is the value at that pixel ) and provided you draw a ...

IntroductionThis example demonstrates the creation of a texture in OpenGL* 4.3 that has a sub-region updated by an OpenCL™ C kernel running on Intel® Processor Graphics with Microsoft Windows*.

The Texture class represents an OpenGL texture object, the TextureCoords class specifies the texture coordinates for a rectangular area of the texture, and the TextureIO class lets you read ...

SUNNYVALE, California -- July 28, 2008 -- Vivante Corporation today announced that it has become the first OpenGL® ES 2.0 3D graphics technology provider to submit conformance results that include the ...

It's also pointed out that regular Cg and HLSL shaders, and Unity 3 surface shaders will be cross-compiled into the OpenGL shading language behind the scenes. GLSL code will be further optimised to ...

In addition to the OpenGL 4.4 specification, the OpenGL ARB (Architecture Review Board) Working Group at Khronos has created the first set of formal OpenGL conformance tests since OpenGL 2.0.
