Member Function Documentation

BVHLayout FW::CudaBVHTracer::getDesiredBVHLayout ( void  ) const

inlinevirtual

Returns

Kernel's desired layout of the BVH buffers.

Implements FW::CudaVirtualTracer.

Definition at line 75 of file CudaBVHTracer.hpp.

void FW::CudaBVHTracer::setBVH ( CudaAS *  bvh )

inlinevirtual

Sets BVH acceleration structure that will be traversed.

Parameters

[in]

bvh

BVH to traverse.

Implements FW::CudaVirtualTracer.

Definition at line 81 of file CudaBVHTracer.hpp.

void CudaBVHTracer::setKernel ( const String &  kernelName )

virtual
