Member Function Documentation

void GEO_PrimPolySoup::appendPolygon ( const UT_Array< GA_Offset > &  vertices)

Appends a polygon to this PolySoup from an array of vertex offsets NOTE: This will not wire the vertices to points or to this primitive, so that must be done manually. This assumes the vertices have already been added to the GEO_TriMesh level with appendVertex or appendVertices.

void GEO_PrimPolySoup::appendPolygonCopyShared ( const GEO_PrimPoly polygon,
GA_VertexWrangler wrangler,
GA_AttributeRefMap attributemap 
)

Appends a copy of a single polygon to this PolySoup, with any vertices whose attributes match being shared among polygons in this PolySoup

void GEO_PrimPolySoup::appendPolygonCopyShared ( const GA_OffsetListRef polygon,
const GA_Detail srcdetail,
GA_VertexWrangler wrangler,
GA_AttributeRefMap attributemap 
)

Appends a copy of a single polygon to this PolySoup, with any vertices whose attributes match being shared among polygons in this PolySoup

void GEO_PrimPolySoup::appendPolygonCopyUnique ( const GEO_PrimPoly polygon,
GA_VertexWrangler wrangler 
)

Appends a copy of a single polygon to this PolySoup, with all vertices unique

void GEO_PrimPolySoup::appendPolygonCopyUnique ( const GA_OffsetListRef polygon,
const GA_Detail srcdetail,
GA_VertexWrangler wrangler 
)

Appends a copy of a single polygon to this PolySoup, with all vertices unique

void GEO_PrimPolySoup::appendPolygons ( const GA_PolyCounts sizes,
const GA_OffsetList vertices 
)

Appends polygons to this PolySoup from an array of vertex offsets NOTE: This will not wire the vertices to points or to this primitive, so that must be done manually. This assumes the vertices have already been added to the GEO_TriMesh level with appendVertex or appendVertices.

void GEO_PrimPolySoup::appendPolySoupCopyShared ( const GEO_PrimPolySoup that,
GA_VertexWrangler wrangler,
GA_AttributeRefMap attributemap 
)

Appends a copy of another PolySoup to this PolySoup, with any vertices whose attributes match being shared among polygons in this PolySoup

void GEO_PrimPolySoup::appendPolySoupCopyUnique ( const GEO_PrimPolySoup that,
GA_VertexWrangler wrangler 
)

Appends a copy of another PolySoup to this PolySoup, with all vertices unique

void GEO_PrimPolySoup::appendSharedVertexCopy ( const GA_Offset  vertex,
const GA_Detail srcdetail,
GA_VertexWrangler wrangler,
GA_AttributeRefMap attributemap 
)
protected
GA_Offset GEO_PrimPolySoup::appendSharedVertices ( GA_Offset  startptoff,
GA_Size  nvertices 
)

This appends one vertex for each of nvertices points starting from startptoff, in parallel, and wires them to the points and this polysoup, then returns the starting vertex offset. Since each point has only one vertex, this applies to making shared vertices. NOTE: The points can't be used by any other primitives at the time that this is called. NOTE: If you leave vertices in the polysoup that are not used by any polygons, areAllVerticesUnique() may return incorrect results, since it just checks if the size of myPolygonVertexList is larger than the size of myVertexList

void GEO_PrimPolySoup::appendUniqueVertexCopy ( const GA_Offset  vertex,
const GA_Detail srcdetail,
GA_VertexWrangler wrangler 
)
protected
GA_Size GEO_PrimPolySoup::appendVertex ( GA_Offset  ptoff)
inlineoverridevirtual

These are only here because of C++ compilers erroring on the appendVertex function below, thinking it should hide these. NOTE: This will not add the vertex to myPolygonVertexList, in case it is to be shared, so use appendPolygon(const UT_Array<GA_Offset> &vertices) to add a polygon with the vertex. NOTE: If you leave vertices in the polysoup that are not used by any polygons, areAllVerticesUnique() may return incorrect results, since it just checks if the size of myPolygonVertexList is larger than the size of myVertexList

bool GEO_PrimPolySoup::areAllVerticesUnique ( ) const
inline

Returns true iff none of the vertices of the PolySoup are shared among multiple polygons in this PolySoup. NOTE: This assumes that every vertex of the PolySoup is in at least one polygon in this PolySoup.

Return the center of the primitive. This defaults to the center of the bounding box. A better approximation might be the average value of the vertex positions (which could be different).

fpreal  u,

) const
overridevirtual

Finds the weightings of the vertices that will compute an interior point given the u,v,w coordinates. The offsets are into the gdp's vertex list, not indices into this primitive's vertex list. Weights are normalized. Note this cannot be used to recover the Position as it often has special case logic (as in spheres, or rational splines), in those cases use evaluateInteriorPoint(UT_Vector4 &pos, ...) It has the advantage over the other evaluateInteriorPoints in that it allows you to avoid creating any temporary vertices. Behaviour for non-sublcassed types is to return the 0th vertex.

void GEO_PrimPolySoup::copyUnwiredForMerge ( const GA_Primitive src,

Copy the specified primitive as part of the merge. The source primitive will be of the same type.

Since the vertex offsets will change for the merged geometry, the map should be used to lookup the new vertex offsets. For example

map.mapDestFromSource( GA_ATTRIB_VERTEX, source_vertex );
