Member Function Documentation

void GEO_PrimSphere::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.

static GEO_PrimSphere* GEO_PrimSphere::build ( GA_Detail detail,
GA_Offset  existing_ptoff = GA_INVALID_OFFSET 
)
inlinestatic

Builds a sphere primitive of the specified type, with either the specified point offset, or a new point if the provided offset is invalid.

overrideprotected
int GEO_PrimSphere::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.

bool GEO_PrimSphere::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_Quadric.

const GA_PrimitiveJSON* GEO_PrimSphere::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.

bool GEO_PrimSphere::hasGuideEdge ( int  edgeid,
UT_Vector3 a,
UT_Vector3 b 
) const
overridevirtual

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.

bool GEO_PrimSphere::hasXsectPoint ( int  pointid,

overridevirtual

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_PrimSphere::registerIntrinsics ( GA_PrimitiveDefinition defn)
inlinestaticprotected

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