Member Function Documentation

virtual void GEO_PrimTriBezier::addPointRefToGroup ( GA_PointGroup grp) const
virtual
virtual void GEO_PrimTriBezier::addToBSphere ( UT_BoundingSphere bsphere) const
virtual

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_PrimTriBezier::baryCenter ( ) const
virtual

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_Primitive.

virtual fpreal GEO_PrimTriBezier::calcVolume ( const UT_Vector3 ) const
virtual

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

Reimplemented from GEO_Primitive.

virtual void GEO_PrimTriBezier::clearForDeletion ( )
protectedvirtual

Private interface The clearForDeletion() method is called just prior to the detail being cleared out. This allows the primitive to simplify its data structures, knowing that topology doesn't need to be maintained (i.e. unwiring all vertices);

Reimplemented from GA_Primitive.

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

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.

virtual UT_Vector3 GEO_PrimTriBezier::computeNormal ( ) const
virtual

Return a normal vector for the primitive.

Implements GEO_Primitive.

virtual GEO_Primitive* GEO_PrimTriBezier::convert ( GEO_ConvertParms parms,
GA_PointGroup usedpts = nullptr 
)
virtual

Implements GEO_Primitive.

virtual GEO_Primitive* GEO_PrimTriBezier::convertNew ( GEO_ConvertParms parms)

virtual GEO_Primitive* GEO_PrimTriBezier::copy ( int  preserve_shared_pts = 0) const
virtual

Reimplemented from GEO_Primitive.

virtual void GEO_PrimTriBezier::copyPrimitive ( const GEO_Primitive src)
virtual

Implements GEO_Primitive.

virtual void GEO_PrimTriBezier::copyUnwiredForMerge ( const GA_Primitive src,
const GA_MergeMap map 
)
virtual

Copy the specified primitive as part of the merge. The source primitive will be of the same type.

Since the vertex offsets will change for the merged geometry, the map should be used to lookup the new vertex offsets. For example

map.mapDestFromSource( GA_ATTRIB_VERTEX, source_vertex );

GA_MergeMap

Reimplemented from GA_Primitive.

virtual void GEO_PrimTriBezier::countMemory ( UT_MemoryCounter counter) const
virtual

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.

virtual GA_DereferenceStatus GEO_PrimTriBezier::dereferencePoint ( GA_Offset  point,
bool  dry_run = false 
)
virtual

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.

Implements GA_Primitive.

virtual GA_DereferenceStatus GEO_PrimTriBezier::dereferencePoints ( const GA_RangeMemberQuery pt_q,

virtual

Implements GEO_Primitive.

virtual bool GEO_PrimTriBezier::evaluateBaryCenterRefMap ( GA_Offset  result_vtx,

) const
protectedvirtual

By default, this will call evaluateInteriorPointRefMap with u=.5 and v=.5. This is likely not the perfect solution. At the current time, this is only used in POPs to birth points at primitive centers.

Reimplemented from GEO_Primitive.

template<typename T >
bool GEO_PrimTriBezier::evaluateMesh ( int  ndivs,
const GA_ROGenericHandleVertex< T > &  h,

Fill a tesselation of the mesh for a given attribute. ndivs must be greater than or equal to 2. The pos array should be able to hold (ndivs)*(ndivs+1)/2 entries.

virtual int GEO_PrimTriBezier::evaluatePointV4 ( UT_Vector4 pos,
float  u,
float  v = 0,
unsigned  du = 0,

) const
protectedvirtual

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.

void GEO_PrimTriBezier::fillArray ( int  fakeorder,

virtual int GEO_PrimTriBezier::getBBox ( UT_BoundingBox bbox) const
virtual

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

Implements GEO_Primitive.

virtual const GA_PrimitiveJSON* GEO_PrimTriBezier::getJSON ( ) const
virtual

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

Stash (deactivate) or unstash (reactivate) the primitive.

Stashing a primitive will set its offset to that specified, typically GA_INVALID_OFFSET. Primitives are only stashed as part of clearing a detail, so there is no need to explicitly deallocate vertices. It is safe to delete a stashed primitive.

Unstashing a primitive will re-register that primitive with its parent detail at the specified offset (or a new offset if GA_INVALID_OFFSET).

Reimplemented from GA_Primitive.

Defragmentation.

Warning
swapVertices() doesn't check the bounds, nor that (i1,j1) != (i2,j2). Use with caution.

Apply the function to each vertex of the primitive. Break when the function returns true. Return the value of the last function applied (false if never called).
