int GD_Curve::breakCount ( ) const

Implements GD_Face.

fpreal GD_Curve::computeBValue ( float  u,
int  i 
) const
GD_Primitive* GD_Curve::copy ( int  preserve_shared_pts = 0) const
overridevirtual

Reimplemented from GD_Primitive.

int GD_Curve::copy ( const GD_Primitive src,
int  ptoffset 
)
overridevirtual

Implements GD_Primitive.

void GD_Curve::copySubclassData ( const GA_Primitive source)
overridevirtual

Copy all subclass data from source to this.

The vertex lists of source and this must already be equivalent in some manner, though possibly referring to different vertices.

If some subclass data is dependent on the vertex list contents, (such as GEO_PrimPolySoup::myPolygonVertexList), it should be mapped based on the correspondence between the two. GEO_PrimPolySoup is currently the only primitive type with this sort of dependence, so it's probably best not to add more.

NOTE: This must be safe to call on different primitives in parallel at the same time.

Reimplemented from GA_Primitive.

void GD_Curve::countMemory ( UT_MemoryCounter counter) const
overridevirtual

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

bool GD_Curve::evaluate ( GA_Offset  vtx,

fpreal  u,
uint  du = 0,

Evaluate the face at the given u position, storing the result in the vertex given by vtx.

Parameters
vtx- Vertex to store evaluated result
h- Handle of attributes to evaluate
u- Parametric evaluation position
du- Derivative
uoffset- Basis offset

Implements GD_Face.

bool GD_Curve::evaluateBreakSegm ( int  ustartidx,
int  ustopidx,
int  lod,
UT_Vector3Array pos,
unsigned  du = 0 
) const
overridevirtual

Evaluate the face between breakpoints by taking a start/stop index in the valid domain and a level of detail representing number of points to be interpolated between every two breakpoints. The method always interpolates the encountered breakpoints (aka "edit points"). This returns true if successful, else false.

Reimplemented from GD_Face.
