Detailed Description

Constructor & Destructor Documentation

SYS_FORCE_INLINE GEO_Primitive::GEO_Primitive ( GA_Detail d,
GA_Offset  offset = GA_INVALID_OFFSET 
)
inlineprotected

NOTE: The constructor should only be called from subclass constructors.

Definition at line 47 of file GEO_Primitive.h.

virtual GEO_Primitive::~GEO_Primitive ( )
inlineprotectedvirtual

NOTE: The destructor should only be called from subclass destructors; only GEO_Detail::destroyStashed() should be calling delete on GEO_Primitive pointers, and GEO_Detail is a friend.

Member Function Documentation

virtual void GEO_Primitive::addToBSphere ( UT_BoundingSphere bsphere) const
virtual

Enlarge the bounding sphere with the primitive's bounds. By default, this will enlarge the bounding sphere by the primitive's bounding box (i.e. getBBox()). It may be possible to have a tighter bound (i.e. the vertex hull for many primitives is a much better metric).

Reimplemented in GEO_PrimVolume, GEO_Hull, GEO_PrimParticle, GEO_PrimTube, GEO_PrimPasteDAG, GEO_PrimSphere, GEO_PrimTriBezier, GEO_TriMesh, GEO_PrimCircle, and GEO_VolumeElement.

virtual UT_Vector3 GEO_Primitive::baryCenter ( ) const
virtual

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).

Reimplemented in GEO_PrimVDB, GEO_PrimVolume, GEO_PrimPolySoup, GEO_Hull, GEO_PrimParticle, HDK_Sample::GEO_PrimTetra, GEO_PrimPacked, GEO_PrimPasteDAG, GEO_Quadric, GEO_PrimTriBezier, GEO_TriMesh, GEO_PrimCircle, and GEO_VolumeElement.

UT_Vector3 nml = 0 
) const

virtual void GEO_Primitive::clip ( UT_Vector3  normal,
float  distance = 0,
GA_PrimitiveGroup clipgrp = NULL

virtual

Reimplemented in GEO_PrimPoly, GU_PrimPoly, and GU_PrimParticle.

virtual void GEO_Primitive::computeInteriorPointWeights ( UT_Array< GA_Offset > &  vtxlist,
UT_Array< float > &  weightlist,
fpreal  u,
fpreal  v,
fpreal  w 
) const
virtual

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.

Reimplemented in GEO_PrimPolySoup, GEO_Curve, GEO_Face, GEO_PrimTetrahedron, GEO_PrimTriBezier, GEO_Hull, GEO_TPSurf, and GEO_PrimPoly.

void GEO_Primitive::copyAttributeData ( const GEO_Primitive src)

Copy the attribute data over from the source primitive. Often you will want to call copyAttributesAndGroups() instead.

void GEO_Primitive::copyAttributeData ( const GEO_Primitive src,
GA_AttributeRefMap gah 
)
void GEO_Primitive::copyAttributeData ( const GEO_Primitive src,
GA_PrimitiveWrangler wrangler 
)
void GEO_Primitive::copyAttributesAndGroups ( const GEO_Primitive src,

Copy attribute data from the source primitive. Also, copy over all the group membership information from the source primitive.

GA_AttributeRefMap gah,

void GEO_Primitive::copyGroupMembership ( const GEO_Primitive src)
