Detailed Description

Definition at line 26 of file GEO_PrimTetrahedron.h.

Constructor & Destructor Documentation

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

NOTE: This constructor should only be called via GU_PrimitiveFactory.

Definition at line 31 of file GEO_PrimTetrahedron.h.

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

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

Definition at line 39 of file GEO_PrimTetrahedron.h.

Member Function Documentation

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

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

static GA_Offset GEO_PrimTetrahedron::buildBlock ( GA_Detail detail,
const GA_Offset  startpt,
const GA_Size  npoints,
const GA_Size  ntets,
const int tetpointnumbers 
)
static

Builds tetrahedrons using the specified range of point offsets, as dictated by ntets and tetpointnumbers, in parallel. tetpointnumbers lists the offsets of the points used by each tetrahedron MINUS startpt, i.e. they are offsets relative to startpt, not indices relative to startpt. The offset of the first tetrahedron is returned, and the rest are at consecutive offsets. All tetpointnumbers must be between 0 (inclusive) and npoints (exclusive).

NOTE: Existing primitives are allowed to be using the points in the specified range already, and the tetrahedrons being created do not do not need to use all of the points in the range. However, these cases may impact performance.

fpreal GEO_PrimTetrahedron::calcArea ( ) const

If the method isn't known, or doesn't make sense, we return 0.

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

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_PrimTetrahedron::iterateEdgesByVertex ( GA_IterateEdgesByVertexFunc  apply_func) const
inlineoverridevirtual

Calls apply_func for each directed edge on the primitive, passing in the GA_Size primitive vertex index for each point on the edge. If the apply_func function returns false, then the traversal will be stopped.

Reimplemented from GA_Primitive.

)
static

Takes (u,v,w) between 0 and 1, and reflects them inside the unit cube so that they fall in the region where (1-u-v-w) >= 0 (and <= 1). That value is written into uvw. This is instantiated for float and double.

void GEO_PrimTetrahedron::reverse ( )

Reverse the order of vertices.

Implements GEO_Primitive.

GA_Offset GEO_PrimTetrahedron::unsafeAppendVertex ( )

NOTE: Do not use this under normal circumstances! This is for if a tet has been added using GA_Detail::appendPrimitive[Block] and vertices have to be added one at a time, e.g. from VEX. It will return GA_INVALID_OFFSET and won't add a vertex if all 4 have already been assigned.

Warning
vertexPoint() doesn't check the bounds. Use with caution.
