HdBufferArrayUsageHint  usageHint 


HDST_API HdStVBOMemoryManager::_StripedBufferArray::~_StripedBufferArray ( )

Destructor. It invalidates _rangeList.

Member Function Documentation

HDST_API HdStBufferResourceSharedPtr HdStVBOMemoryManager::_StripedBufferArray::_AddResource ( TfToken const name,
HdTupleType  tupleType,
int  offset,
int  stride 

Adds a new, named GPU resource and returns it.

HDST_API void HdStVBOMemoryManager::_StripedBufferArray::_DeallocateResources ( )
HDST_API void HdStVBOMemoryManager::_StripedBufferArray::DebugDump ( std::ostream &  out) const

Debug output.

Implements HdBufferArray.

HDST_API bool HdStVBOMemoryManager::_StripedBufferArray::GarbageCollect ( )

perform compaction if necessary. If it becomes empty, release all resources and returns true

Implements HdBufferArray.

HDST_API HdBufferSpecVector HdStVBOMemoryManager::_StripedBufferArray::GetBufferSpecs ( ) const

Reconstructs the bufferspecs and returns it (for buffer splitting)

HDST_API size_t HdStVBOMemoryManager::_StripedBufferArray::GetMaxNumElements ( ) const

Returns the maximum number of elements capacity.

Reimplemented from HdBufferArray.

HDST_API HdStBufferResourceSharedPtr HdStVBOMemoryManager::_StripedBufferArray::GetResource ( ) const

TODO: We need to distinguish between the primvar types here, we should tag each HdBufferSource and HdBufferResource with Constant, Uniform, Varying, Vertex, or FaceVarying and provide accessors for the specific buffer types. Returns the GPU resource. If the buffer array contains more than one resource, this method raises a coding error.

HDST_API HdStBufferResourceSharedPtr HdStVBOMemoryManager::_StripedBufferArray::GetResource ( TfToken const name)

Returns the named GPU resource. This method returns the first found resource. In HD_SAFE_MODE it checks all underlying GL buffers in _resourceMap and raises a coding error if there are more than one GL buffers exist.

HdStBufferResourceNamedList const& HdStVBOMemoryManager::_StripedBufferArray::GetResources ( ) const

Returns the list of all named GPU resources for this bufferArray.

Definition at line 301 of file vboMemoryManager.h.

HDST_API void HdStVBOMemoryManager::_StripedBufferArray::Reallocate ( std::vector< HdBufferArrayRangeSharedPtr > const ranges,
HdBufferArraySharedPtr const curRangeOwner 

Performs reallocation. GLX context has to be set when calling this function.

Implements HdBufferArray.

void HdStVBOMemoryManager::_StripedBufferArray::SetNeedsCompaction ( )

Mark to perform compaction on GarbageCollect()

Definition at line 279 of file vboMemoryManager.h.

void HdStVBOMemoryManager::_StripedBufferArray::SetNeedsReallocation ( )

Mark to perform reallocation on Reallocate()

Definition at line 274 of file vboMemoryManager.h.
