  1. I'm trying to understand and to run Apple's OpenCL examples on Windows 7. I have a questions regarding they kernels code. I'm primarily interested in noise on OpenCL and the only available source is Apple examples. http://developer.apple.com/library/mac/nav...mp;topic=OpenCL static const float4 ZERO_F4 = (float4)(0.0f, 0.0f, 0.0f, 0.0f); static const float4 ONE_F4 = (float4)(1.0f, 1.0f, 1.0f, 1.0f); "static" is not allowed in OpenCL C, so I replaced it with just "__constant", but then I notices that it is not used, so better to comment out these. Why Apple not remove this? int mod(int x, int a) { int n = (x / a); int v = v - n * a; if ( v < 0 ) v += a; return v; } Same as before, this code is not actually used. But if it would be used notice that "v" is used without being initilized. But by the meaning of code shouldn't it be like this "int v = x - n * a;"? float remainder = 0.0f; float sample = 0.0f; Variables are not used, compiler just generates warnings. Apple could remove these too.
