Web30 de nov. de 2009 · I was told previously to use uint4’s for extra speed when coding OpenCL kernels for my HD4870 GPU, but there seems to be a little ambiguity in terms of what a uint4 is. A quick Google search tells me it’s simply a 4-byte unsigned integer, but deeper research reveals in the context of OpenCL it’s actually a vector type, consisting … WebThe min () operator is there to prevent fract (-small ) from returning 1.0.
