Detailed Description

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);
