Detailed Description

A primitive made of multiple fragments that are coalesced into one geometry

For each fragment, you can query:

  • The transform for the fragment
  • The untransformed bounding box
  • The transformed bounding box
  • The fragment's __primitive_id
  • The fragment's __point_id These properties are only used for information, not for refinement or rendering. The single geometry is composed of the transformed fragments.

Attributes are:

  • detail: one for the whole primitive The instance primitive does not pass these down when it refines.

Set up __primitive_id, __point_id and __vertex_id explicitly The arrays can be NULL.

void GT_PrimFragments::setSourceGeometry ( const GT_GEODetailListHandle g)
inline

If the geometry being instanced comes from a GU_Detail, then the source geometry should be set to point to this geometry. This lets viewport decorations be rendered properly.

void GT_PrimFragments::setupFragments ( const GT_GEOOffsetList primitives,
const GT_GEOOffsetList vertices,
const GT_GEOOffsetList points,
const GT_DataArrayHandle centroids 
)

Set up __primitive_id, __point_id and transforms based on fragment primitives. This assumes that the primitives are all packed primitives of some kind (and have a single point).

The centroids should likely be in the center of the transformed bounding box.
