Detailed Description

Definition at line 32 of file GEO_PrimHexahedron.h.

Constructor & Destructor Documentation

SYS_FORCE_INLINE GEO_PrimHexahedron::GEO_PrimHexahedron ( GA_Detail d,
GA_Offset  offset = GA_INVALID_OFFSET 
)
inline

NOTE: This constructor should only be called via GU_PrimitiveFactory.

Definition at line 37 of file GEO_PrimHexahedron.h.

SYS_FORCE_INLINE GEO_PrimHexahedron::GEO_PrimHexahedron ( GA_Detail gdp,
GA_Offset  offset,
const GA_OffsetListRef vertex_list 
)
inline

This constructor is for making a representation of a hexahedron on the stack, so that you can call GEO_PrimHexahedron functions on the hexahedron without needing the detail to allocate one.

Definition at line 45 of file GEO_PrimHexahedron.h.

Member Function Documentation

void GEO_PrimHexahedron::allocateVertices ( )
protected
static GEO_PrimHexahedron* GEO_PrimHexahedron::build ( GEO_Detail gdp,
bool  appendPts = true 
)
static

Builds a single hexahedron primitive, optionally creating new points and wiring them to its vertices.

fpreal GEO_PrimHexahedron::calcArea ( ) const
overridevirtual

Measure the primitive.

Reimplemented from GA_Primitive.

fpreal GEO_PrimHexahedron::calcPerimeter ( ) const
overridevirtual

Measure the primitive.

Reimplemented from GA_Primitive.

fpreal GEO_PrimHexahedron::calcVolume ( const UT_Vector3 refpt) const
overridevirtual

Measure the primitive.

Reimplemented from GA_Primitive.

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

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 from GEO_Primitive.

Return a normal vector for the primitive.

void GEO_PrimHexahedron::countMemory ( UT_MemoryCounter counter) const

Count memory usage using a UT_MemoryCounter in order to count shared memory correctly. NOTE: This should always include sizeof(*this).

Reimplemented from GA_Primitive.

GA_DereferenceStatus GEO_PrimHexahedron::dereferencePoint ( GA_Offset  point,
bool  dry_run = false

Before a point is deleted, all primitives using the point will be notified. The method should return "false" if it's impossible to delete the point. Otherwise, the vertices should be removed.
