Detailed Description

Constructor & Destructor Documentation

GEO_PrimTetra::~GEO_PrimTetra ( )
protectedvirtual

NOTE: The destructor should only be called from GA_PrimitiveList, via a GA_Primitive pointer.

Examples:
tetprim/GEO_PrimTetra.h.

Definition at line 84 of file GEO_PrimTetra.C.

GEO_PrimTetra::GEO_PrimTetra ( GA_Detail d,
GA_Offset  offset 
)

NOTE: To create a new primitive owned by the detail, call GA_Detail::appendPrimitive or appendPrimitiveBlock on the detail, not this constructor.

Examples:
tetprim/GEO_PrimTetra.C, and tetprim/GEO_PrimTetra.h.

Definition at line 75 of file GEO_PrimTetra.C.

Member Function Documentation

UT_Vector3 GEO_PrimTetra::baryCenter ( ) const
virtual

Optional interface methods. Though not required, implementing these will give better behaviour for the new primitive.

Reimplemented from GEO_Primitive.

Examples:
tetprim/GEO_PrimTetra.C, and tetprim/GEO_PrimTetra.h.

Definition at line 427 of file GEO_PrimTetra.C.

GEO_PrimTetra * GEO_PrimTetra::build ( GA_Detail gdp,
bool  appendpts = true 
)
static

Optional build function.

Examples:
tetprim/GEO_PrimTetra.C, tetprim/GEO_PrimTetra.h, and tetprim/SOP_Tetra.C.

Definition at line 508 of file GEO_PrimTetra.C.

GA_Offset GEO_PrimTetra::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.

Examples:
tetprim/GEO_PrimTetra.C, and tetprim/GEO_PrimTetra.h.

Definition at line 600 of file GEO_PrimTetra.C.

void GEO_PrimTetra::stashed ( bool  beingstashed,
GA_Offset  offset = GA_INVALID_OFFSET 
)
virtual

Though not strictly required (i.e. not pure virtual), these methods should be implemented for proper behaviour.

Reimplemented from GA_Primitive.

Examples:
tetprim/GEO_PrimTetra.C, and tetprim/GEO_PrimTetra.h.

Definition at line 94 of file GEO_PrimTetra.C.

static const GA_PrimitiveTypeId& HDK_Sample::GEO_PrimTetra::theTypeId ( )
inlinestatic

Allows you to find out what this primitive type was named.
