Member Function Documentation

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

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.

UT_Vector3 GEO_PrimTriBezier::baryCenter ( ) const
overridevirtual

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).

overridevirtual

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

Reimplemented from GEO_Primitive.

fpreal GEO_PrimTriBezier::calcVolume ( const UT_Vector3 ) const
overridevirtual

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.

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

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.

UT_Vector3 GEO_PrimTriBezier::computeNormal ( ) const
overridevirtual

Return a normal vector for the primitive.

Implements GEO_Primitive.

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

Implements GEO_Primitive.

GEO_Primitive* GEO_PrimTriBezier::convertNew ( GEO_ConvertParms parms)
overridevirtual

Implements GEO_Primitive.

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

Reimplemented from GEO_Primitive.

void GEO_PrimTriBezier::copyPrimitive ( const GEO_Primitive src)
overridevirtual

Implements GEO_Primitive.

void GEO_PrimTriBezier::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 GEO_PrimTriBezier::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).

Reimplemented from GA_Primitive.

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

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.

GA_DereferenceStatus GEO_PrimTriBezier::dereferencePoints ( const GA_RangeMemberQuery pt_q,
bool  dry_run = false 
)
overridevirtual

Implements GA_Primitive.

int GEO_PrimTriBezier::detachPoints ( GA_PointGroup grp)
overridevirtual

Implements GEO_Primitive.

bool GEO_PrimTriBezier::evaluateBaryCenterRefMap ( GA_Offset  result_vtx,
GA_AttributeRefMap map 
) const
overrideprotectedvirtual

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,
T pos 
) const

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.

GA_AttributeRefMap hlist,
fpreal  u,
fpreal  v,

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

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,
UT_Vector4 array 
) const
void GEO_PrimTriBezier::fillArray ( int  fakeorder,
const GA_Offset results,
GA_AttributeRefMap hlist 
) const
int GEO_PrimTriBezier::getBBox ( UT_BoundingBox bbox) const
overridevirtual

Compute the bounding box of the primitive. Return 0 if unable to compute bounds (1 on successful computation). This function should always initialize bbox, even if returning false, in which case, the bbox->isValid() may be false, representing an empty bounding box. This function should also not use any initial value of bbox, so it does not need to be initialized beforehand.

Implements GEO_Primitive.

const GA_PrimitiveJSON* GEO_PrimTriBezier::getJSON ( ) const
overridevirtual

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.

Report approximate memory usage.

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.

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).
