Member Function Documentation

void Bind ( VERTEX_BUFFER *  in, int  iOfs, VERTEX_BUFFER *  out, int  oOfs  )

inline

Binds a vertex and a varying data buffers to the context. Binding ensures that data buffers are properly inter-operated between Contexts and Controllers operating across multiple devices.

Parameters

in	a buffer containing input vertex-interpolated primvar data
iOfs	offset to the buffer element describing the vertex position
out	a buffer where the smooth normals will be output
oOfs	offset to the buffer element describing the normal position

Definition at line 71 of file cpuSmoothNormalContext.h.

static CpuSmoothNormalContext* Create ( Far::PatchTables const *  patchTables, bool  resetMemory = false  )

static

Creates an CpuComputeContext instance

Parameters

patchTables	The Far::PatchTables used for this Context.
resetMemory	Set to true if the target vertex buffer needs its memory reset before accumulating the averaged normals. If the SmoothNormal Controller runs after a Computer Controller, then the vertex buffer will already have been reset and this step can be skipped to save time.

const std::vector<unsigned int>& GetControlVertices ( ) const

inline

The ordered array of control vertex indices for all the patches.

Definition at line 102 of file cpuSmoothNormalContext.h.

float const* GetCurrentInputVertexBuffer ( ) const

inline

Returns a pointer to the data of the input buffer.

Definition at line 107 of file cpuSmoothNormalContext.h.

float* GetCurrentOutputVertexBuffer ( )

inline

Returns a pointer to the data of the output buffer.

Definition at line 112 of file cpuSmoothNormalContext.h.

VertexBufferDescriptor const& GetInputVertexDescriptor ( ) const

inline

Returns an VertexDescriptor for the input vertex data.

Definition at line 117 of file cpuSmoothNormalContext.h.

int GetNumVertices ( ) const

inline

Returns the number of vertices in output vertex buffer.

Definition at line 128 of file cpuSmoothNormalContext.h.

VertexBufferDescriptor const& GetOutputVertexDescriptor ( ) const

inline

Returns an VertexDescriptor for the buffer where the normals data will be stored

Definition at line 123 of file cpuSmoothNormalContext.h.

const Far::PatchTables::PatchArrayVector& GetPatchArrayVector ( ) const

inline

Returns the vector of patch arrays.

Definition at line 97 of file cpuSmoothNormalContext.h.

bool GetResetMemory ( ) const

inline

Returns whether the controller needs to reset the vertex buffer before accumulating smooth normals

Definition at line 134 of file cpuSmoothNormalContext.h.

void SetResetMemory ( bool  resetMemory )

inline

Set to true if the controller needs to reset the vertex buffer before accumulating smooth normals

Definition at line 140 of file cpuSmoothNormalContext.h.

void Unbind ( )

inline

Unbinds any previously bound vertex and varying data buffers.

Definition at line 88 of file cpuSmoothNormalContext.h.
