List of common graphics capabilities of the device used by a SoGLContext.
This structure aims at making algorithms scalable according to the capabilities of the device used for execution. For instance, a texture can be resized if its size is greater than supported hardware size, such as:
const SbGraphicsCapabilities& caps = SoGLContext::getGraphicsCapabilities(); if (texSize > caps.maxTextureSize) resizeTexture(caps.maxTextureSize);
