Detailed Description

Compute controller for launching OpenMP subdivision kernels.

OmpComputeController is a compute controller class to launch OpenMP threaded subdivision kernels. It requires CpuVertexBufferInterface as arguments of Refine function.

Controller entities execute requests from Context instances that they share common interfaces with. Controllers are attached to discrete compute devices and share the devices resources with Context entities.

void Compute ( CpuComputeContext const *  context, Far::KernelBatchVector const &  batches, VERTEX_BUFFER *  vertexBuffer, VARYING_BUFFER *  varyingBuffer, VertexBufferDescriptor const *  vertexDesc = NULL, VertexBufferDescriptor const *  varyingDesc = NULL  )

inline

Execute subdivision kernels and apply to given vertex buffers.

Parameters

context	The CpuContext to apply refinement operations to
batches	Vector of batches of vertices organized by operative kernel
vertexBuffer	Vertex-interpolated data buffer
vertexDesc	The descriptor of vertex elements to be refined. if it's null, all primvars in the vertex buffer will be refined.
varyingBuffer	Vertex-interpolated data buffer
varyingDesc	The descriptor of varying elements to be refined. if it's null, all primvars in the vertex buffer will be refined.
