Detailed Description

Storage arrays for vertex data for opensubdiv classes.

Member Typedef Documentation

using GT_OSDAttributes::AttribId = std::pair<int, bool>

Identifier for an attribute. The first item is the index in the attribute list, the second is whether it's a vertex or a point attribute.

Definition at line 345 of file GT_OSD3.h.

bool GT_OSDAttributes::coarseValues ( const AttribId attrib,
const GT_Size vertices,
GT_Size  nvtx,

) const

Extract attributes on the coarse mesh.

void GT_OSDAttributes::dump ( ) const
void GT_OSDAttributes::dump ( UT_JSONWriter w) const
GT_DataArrayHandle GT_OSDAttributes::extractFaceMap ( const GT_OSDTopology top,
int  level_index 
) const

Extract a mapping from fine faces at a given refinement level to its corresponding coarse face

GT_FaceSetMapPtr GT_OSDAttributes::extractFaceSets ( const GT_OSDTopology top,
int  level_index 
) const

Extract a face map set for a mesh at the given refinement level.

GT_PrimitiveHandle GT_OSDAttributes::extractMesh ( const GT_OSDTopology topology,
bool  harden,
int  level = -1 
)

Extract a subdivided mesh for the given topology level.

GT_AttributeListHandle GT_OSDAttributes::extractShared ( const GT_OSDTopology top,
int  level_index,
bool  harden 
) const

Extract the shared/point attributes for a mesh at the given refinement level. If harden is false, the attributes lists will point to the temporary buffers (which are over-sized). Passing true to harden will copy out the temporary data into compact arrays.

GT_AttributeListHandle GT_OSDAttributes::extractUniform ( const GT_OSDTopology top,
int  level_index,
bool  harden 
) const

Extract the primitive/face attributes for a mesh at the given refinement level.

GT_AttributeListHandle GT_OSDAttributes::extractVertex ( const GT_OSDTopology top,
int  level_index,
bool  harden 
) const

Extract the vertex/face-varying attributes for a mesh at the given refinement level. See extractShared for help on harden

const UT_Array<Vertex>& GT_OSDAttributes::facevaryingArray ( ) const
inline

Definition at line 557 of file GT_OSD3.h.

AttribId GT_OSDAttributes::findAttribute ( const char *  name) const

Find an attribute

AttribId GT_OSDAttributes::findAttribute ( const char *  name,
bool  vertex_attrib 
) const

Find an attribute

template<typename T >
const T* GT_OSDAttributes::getData ( int  attrib,
int  index,
int  seg 
) const
inline

Return a pointer to the index-th entry in the given attribute array. If the index exceeds or equals the number of coarse vertices (myFineOffset), then the data is located in the fine attribute array. The first element of the fine attribute array has index equal to myFineOffset, so we do pointer arithmetic to shift the array by myFineOffset entries.

Definition at line 591 of file GT_OSD3.h.

template<typename T >
const T* GT_OSDAttributes::getDataFV ( int  attrib,
int  index,
int  seg 
) const
inline

Same idea as with getData, but with face varying data.

Definition at line 606 of file GT_OSD3.h.

int GT_OSDAttributes::tupleSize ( const AttribId attrib) const

Return the size of a given attribute.
