Member Function Documentation

HDST_API size_t HdStDrawItem::GetBufferArraysHash ( ) const

Returns the hash of the versions of underlying buffers. When the hash changes, it means the drawing coord might have been reassigned, so any drawing coord caching buffer (e.g. indirect dispatch buffer) has to be rebuilt at the moment. Note that this value is a hash, not sequential.

HdBufferArrayRangeSharedPtr const& HdStDrawItem::GetConstantPrimvarRange ( ) const
inline

Returns constant primvar BAR.

Definition at line 87 of file drawItem.h.

HDST_API size_t HdStDrawItem::GetElementOffsetsHash ( ) const

Returns the hash of the element offsets of the underlying BARs. When the hash changes, it means that any drawing coord caching buffer (e.g. the indirect dispatch buffer) has to be rebuilt. Note that this value is a hash, not sequential.

HdBufferArrayRangeSharedPtr const& HdStDrawItem::GetElementPrimvarRange ( ) const
inline

Returns element primvar BAR.

Definition at line 93 of file drawItem.h.

HdBufferArrayRangeSharedPtr const& HdStDrawItem::GetFaceVaryingPrimvarRange ( ) const
inline

Returns face varying primvar BAR.

Definition at line 111 of file drawItem.h.

TopologyToPrimvarVector const& HdStDrawItem::GetFvarTopologyToPrimvarVector ( ) const
inline

Returns mapping from refined fvar channels to named primvar.

Definition at line 129 of file drawItem.h.

HdSt_GeometricShaderSharedPtr const& HdStDrawItem::GetGeometricShader ( ) const
inline

Definition at line 137 of file drawItem.h.

HdBufferArrayRangeSharedPtr const& HdStDrawItem::GetInstanceIndexRange ( ) const
inline

Returns instance-index indirection BAR.

Definition at line 81 of file drawItem.h.

int HdStDrawItem::GetInstancePrimvarNumLevels ( ) const
inline

Returns the number of nested levels of instance primvars.

Definition at line 58 of file drawItem.h.

HdBufferArrayRangeSharedPtr const& HdStDrawItem::GetInstancePrimvarRange ( int  level) const
inline

Returns a BufferArrayRange of instance primvars at level the level is assigned to nested instancers in a bottom-up manner.

example: (numLevels = 2)

instancerA         (level = 1)
  |
  +-- instancerB   (level = 0)
        |
        +-- mesh_prototype

bool HdStDrawItem::HasInstancer ( ) const
inline

Returns true if the drawItem has an instancer.

HdStDrawItem::HF_MALLOC_TAG_NEW ( "new HdStDrawItem )
HDST_API bool HdStDrawItem::IntersectsViewVolume ( GfMatrix4d const viewProjMatrix) const

Tests intersection with the specified view projection matrix. Returns true if this drawItem is in the frustum.

XXX: Currently if this drawitem uses instancing, always returns true.
