Constructor & Destructor Documentation

GEO_Quadric::GEO_Quadric ( GEO_Detail d,
GA_Offset  offset = GA_INVALID_OFFSET 
)
protected

NOTE: The constructor should only be called from subclass constructors.

virtual GEO_Quadric::~GEO_Quadric ( )
protectedvirtual

NOTE: The destructor should only be called from subclass destructors.

Member Function Documentation

virtual void GEO_Quadric::addPointRefToGroup ( GA_PointGroup grp) const
virtual
void GEO_Quadric::assignVertex ( GA_Offset  new_vtx,
bool  update_topology 
)

This method assigns a preallocated vertex to the quadric, optionally creating the topological link between the primitive and new vertex.

virtual UT_Vector3 GEO_Quadric::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.

Reimplemented in GEO_PrimCircle.

static GEO_Quadric* GEO_Quadric::build ( GA_Detail detail,
GA_PrimitiveTypeId  type,
GA_Offset  existing_ptoff = GA_INVALID_OFFSET 
)
static

Builds a quadric primitive of the specified type, with either the specified point offset, or a new point if the provided offset is invalid. NOTE: type must be GA_PRIMSPHERE, GA_PRIMCIRCLE, GA_PRIMTUBE, GA_PRIMMETABALL, or GA_PRIMMETASQUAD.

static GA_Offset GEO_Quadric::buildBlock ( GA_Detail detail,
GA_PrimitiveTypeId  type,
GA_Size  nprims,
bool  append_points = true 
)
static

Builds a contiguous block of nprims quadric primitives of the specified type, appending a block of new points for them if append_points is true, else leaving the vertices unwired. NOTE: type must be GA_PRIMSPHERE, GA_PRIMCIRCLE, GA_PRIMTUBE, GA_PRIMMETABALL, or GA_PRIMMETASQUAD.

static GA_PrimitiveFamilyMask GEO_Quadric::buildFamilyMask ( )
inlinestaticprotected

Return the family mask for all quadric sub-classes.

Definition at line 276 of file GEO_Quadric.h.

virtual void GEO_Quadric::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 UT_Vector3 GEO_Quadric::computeNormal ( ) const
virtual

Return a normal vector for the primitive.

Implements GEO_Primitive.

Reimplemented in GEO_PrimCircle.

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

Reimplemented from GEO_Primitive.

Reimplemented in GEO_PrimTube, GEO_PrimMetaBall, and GEO_PrimMetaSQuad.

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

Implements GEO_Primitive.

Reimplemented in GEO_PrimTube, GEO_PrimMetaBall, and GEO_PrimMetaSQuad.

virtual void GEO_Quadric::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 );
See Also
GA_MergeMap

Reimplemented from GA_Primitive.

Reimplemented in GEO_PrimTube, GEO_PrimMetaBall, and GEO_PrimMetaSQuad.

virtual GA_DereferenceStatus GEO_Quadric::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_Quadric::dereferencePoints ( const GA_RangeMemberQuery pt_q,
bool  dry_run = false 
)
virtual

Implements GA_Primitive.

virtual int GEO_Quadric::detachPoints ( GA_PointGroup grp)
virtual

Implements GEO_Primitive.

virtual bool GEO_Quadric::enlargeBoundingBox ( UT_BoundingRect b,
const GA_Attribute P 
) const
virtual

Enlarge a bounding box by the bounding box of the primitive. A return value of false indicates an error in the operation, most likely an invalid P. For any attribute other than the position these methods simply enlarge the bounding box based on the vertex.

Reimplemented from GEO_Primitive.

virtual bool GEO_Quadric::enlargeBoundingBox ( UT_BoundingBox b,
const GA_Attribute P 
) const
virtual

Enlarge a bounding box by the bounding box of the primitive. A return value of false indicates an error in the operation, most likely an invalid P. For any attribute other than the position these methods simply enlarge the bounding box based on the vertex.

Reimplemented from GEO_Primitive.

virtual bool GEO_Quadric::enlargeBoundingSphere ( UT_BoundingSphere b,
const GA_Attribute P 
) const
virtual

Enlarge a bounding sphere to encompass the primitive. A return value of false indicates an error in the operation, most likely an invalid P. For any attribute other than the position this method simply enlarges the sphere based on the vertex.

Reimplemented from GA_Primitive.

virtual void GEO_Quadric::enlargePointBounds ( UT_BoundingBox e) const
virtual

Enlarge a bounding box by the bounding box of the primitive. A return value of false indicates an error in the operation, most likely an invalid P. For any attribute other than the position these methods simply enlarge the bounding box based on the vertex.

Reimplemented from GA_Primitive.

virtual bool GEO_Quadric::evaluateBaryCenterRefMap ( GA_Offset  result_vtx,
GA_AttributeRefMap map 
) 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.

protected
void GEO_Quadric::getAxes ( UT_Vector3 x,
UT_Vector3 y,

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

Return the local transform matrix for the primitive. Some primitives don't store transforms (see hasLocalTransform()). The default behaviour is to make the transform an identity.

virtual void GEO_Quadric::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).

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).
