Constructor & Destructor Documentation

HDST_API HdStInterleavedMemoryManager::_StripedInterleavedBuffer::_StripedInterleavedBuffer ( Hgi hgi,
TfToken const role,
HdBufferSpecVector const bufferSpecs,
HdBufferArrayUsageHint  usageHint,
int  bufferOffsetAlignment,
int  structAlignment,
size_t  maxSize,
TfToken const garbageCollectionPerfToken 


virtual HDST_API HdStInterleavedMemoryManager::_StripedInterleavedBuffer::~_StripedInterleavedBuffer ( )

Destructor. It invalidates _rangeList.

Member Function Documentation

HDST_API HdStBufferResourceGLSharedPtr HdStInterleavedMemoryManager::_StripedInterleavedBuffer::_AddResource ( TfToken const name,
HdTupleType  tupleType,
int  offset,
int  stride 

Adds a new, named GPU resource and returns it.

HDST_API void HdStInterleavedMemoryManager::_StripedInterleavedBuffer::_DeallocateResources ( )
virtual HDST_API void HdStInterleavedMemoryManager::_StripedInterleavedBuffer::DebugDump ( std::ostream &  out) const

Debug output.

Implements HdBufferArray.

virtual HDST_API bool HdStInterleavedMemoryManager::_StripedInterleavedBuffer::GarbageCollect ( )

perform compaction if necessary, returns true if it becomes empty.

Implements HdBufferArray.

HDST_API HdBufferSpecVector HdStInterleavedMemoryManager::_StripedInterleavedBuffer::GetBufferSpecs ( ) const

Reconstructs the bufferspecs and returns it (for buffer splitting)

HDST_API HdStBufferResourceGLSharedPtr HdStInterleavedMemoryManager::_StripedInterleavedBuffer::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 HdStBufferResourceGLSharedPtr HdStInterleavedMemoryManager::_StripedInterleavedBuffer::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.

HdStBufferResourceGLNamedList const& HdStInterleavedMemoryManager::_StripedInterleavedBuffer::GetResources ( ) const

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

Definition at line 248 of file interleavedMemoryManager.h.

int HdStInterleavedMemoryManager::_StripedInterleavedBuffer::GetStride ( ) const

Returns the stride.

Definition at line 226 of file interleavedMemoryManager.h.

virtual HDST_API void HdStInterleavedMemoryManager::_StripedInterleavedBuffer::Reallocate ( std::vector< HdBufferArrayRangeSharedPtr > const ranges,
HdBufferArraySharedPtr const curRangeOwner 

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

Implements HdBufferArray.

void HdStInterleavedMemoryManager::_StripedInterleavedBuffer::SetNeedsCompaction ( )

Mark to perform compaction on GarbageCollect()

Definition at line 221 of file interleavedMemoryManager.h.

void HdStInterleavedMemoryManager::_StripedInterleavedBuffer::SetNeedsReallocation ( )

Mark to perform reallocation on Reallocate()

Definition at line 216 of file interleavedMemoryManager.h.
