Member Function Documentation

virtual void GEO_PrimCircle::addToBSphere ( UT_BoundingSphere bsphere) const

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 from GEO_Primitive.

virtual UT_Vector3 GEO_PrimCircle::baryCenter ( ) const

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 from GEO_Quadric.

static GA_PrimitiveFamilyMask GEO_PrimCircle::buildFamilyMask ( )

Definition at line 62 of file GEO_PrimCircle.h.

virtual fpreal GEO_PrimCircle::calcArea ( ) const

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

Reimplemented from GEO_Primitive.

virtual fpreal GEO_PrimCircle::calcPerimeter ( ) const

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

Reimplemented from GEO_Primitive.

virtual fpreal GEO_PrimCircle::calcVolume ( const UT_Vector3 ) const

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

Reimplemented from GEO_Primitive.

virtual UT_Vector3 GEO_PrimCircle::computeNormal ( ) const

Return a normal vector for the primitive.

Reimplemented from GEO_Quadric.

virtual bool GEO_PrimCircle::evaluatePointRefMap ( GA_Offset  result_vtx,
GA_AttributeRefMap hlist,
fpreal  u_unit,
fpreal  ,
uint  du,
) const

Implements GEO_Primitive.

virtual int GEO_PrimCircle::evaluatePointV4 ( UT_Vector4 pos,
float  u,
float  v = 0,
unsigned  du = 0,
unsigned  dv = 0 
) const

Evaluate the position for the given parametric coordinates (with the given derivatives). Return 0 if successful, or -1 if failure. The default implementation returns {0,0,0,0};

Reimplemented from GEO_Primitive.

virtual int GEO_PrimCircle::getBBox ( UT_BoundingBox bbox) const

Compute the bounding box of the primitive. Return 0 if unable to compute bounds (1 on successful computation)

Implements GEO_Quadric.

virtual const GA_PrimitiveJSON* GEO_PrimCircle::getJSON ( ) const

This method returns the JSON interface for saving/loading the primitive If the method returns a NULL pointer, then the primitive will not be saved to geometry files (and thus cannot be loaded).

Implements GA_Primitive.

virtual bool GEO_PrimCircle::hasGuideEdge ( int  edgeid,
UT_Vector3 a,
UT_Vector3 b 
) const

These functions are only implemented to get guide points/edges for spheres, tubes, and circles. The ID meaning is type-specific.

Reimplemented from GEO_Primitive.

virtual bool GEO_PrimCircle::hasXsectPoint ( int  pointid,
UT_Vector3 p 
) const

These functions are only implemented to get guide points/edges for spheres, tubes, and circles. The ID meaning is type-specific.

Reimplemented from GEO_Primitive.

static GA_IntrinsicManager::Registrar GEO_PrimCircle::registerIntrinsics ( GA_PrimitiveDefinition defn)

All subclasses should call this method to register the curve intrinsics.
