Calculate the limit subdivision point using the catmull-clark masks. If you use this operation, further subdivision using this vertex will not produce the correct result.

Get per-face vertex data if it exists. You should use getFaceIndex() to retrieve the face index to be passed to this operation.

void GU_SubDivVertex::scaleVertex ( fpreal  scale,

void GU_SubDivVertex::setAllIncomplete ( )

Set and get completion status. We're complete when all our neighbouring edges and faces are defined.

GU_SubDivEdge* GU_SubDivVertex::setEdge ( GU_SubDivVertex vtx,
int  idx = -1,

Adds vtx at the specified position in my edge table. If idx == -1, then add vtx to the next available position. Returns the edge.

int  idx 
)
inline

Definition at line 145 of file GU_SubDivPatch.h.

void GU_SubDivVertex::setFace ( GU_SubDivPatch face,
int  idx = -1 
)

Add the face to the specified position in my face table. If idx == -1, then we'll analyse the edges in the face to decide where to put it.

void GU_SubDivVertex::setVertexData ( const float *  data,
int  idx,
const UT_IntArray offsets 
)

Set vertex data. The index is a face identifier in the current vertex. If a vertex seam is detected, we'll allocate separate face vertex data. The offset array is used to isolate individual vertex attributes so that we can have an independent hard edge mask for each attribute. The offsets are in number of floats and point to the start of each attribute.

void GU_SubDivVertex::setWeight ( fpreal  weight,
bool  linear,
const GU_SubDivPatch face 
)
void GU_SubDivVertex::sortEdges ( )

Order the edges using the face set for this vertex.
