Function Documentation

cl_init()

void cl_init ( cl::Device &  device_out, cl::Context &  context_out, cl::CommandQueue &  queue_out, cl_device_type  devType = CL_DEVICE_TYPE_GPU  )

inline

descriptionOfError()

const char* descriptionOfError ( cl_int  err )

inline

generateEmbeddableSource()

int generateEmbeddableSource ( QString  src_filename, QString  output_filename  )

inline

GetLocalForKernel()

size_t GetLocalForKernel ( const cl::Kernel  kernel, const size_t  global, const cl::Device  device  )

inline

Get best fitting 1D local size given the global size and an OpenCL kernel.

Global size should be dividable by local size. And local size should not be more than the maximum number of threads that kernel can handle.

readFile()

QString readFile ( QString  filename )

inline

Vec3_to_cl_float4()

cl_float4 Vec3_to_cl_float4 ( const iAVec3f &  v )
