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.

Enlarge a point bounding box for implicit primitive bounds. If a primitive (such as a sphere) has a bounding box larger than its point hull, then it should implement this method. Otherwise, it can rely on the default behaviour.
NOTE: If you make a custom primitive type whose bounding box may be larger than the bounding box of the points referenced by vertices of the primitive, you must override this function in order for the detail's bounding box to be correctly computed. It does not suffice to override GEO_Primitive::getBBox(), since GA_Detail::computeQuickBounds will find the point bounding box of the entire detail, and then call enlargePointBounds on all primitives except polygons, tetrahedra, polysoups, and other primitive types that are known in advance to not exceed their point bounding boxes.

If the edge is not in this primitive, vtx0 and vtx1 will not be written-to, and the function will return false. When written, vtx0->vtx1 will always be the direction the edge appears in this primitive, which may be opposite ptoff0->ptoff1.

Return the next and previous vertex on the "boundary" of the primitive (as understood by the primitive) relative to a given vertex. These are needed to maintain half-edge topology attributes. They must be implemented for primitives that realize a notion of a boundary composed of one or more closed cycles of vertices if we want to be able to use hedges to quickly move from such a primitive to another sharing an edge with it. A GA_INVALID_OFFSET for prev_vtx or next_vtx means that either the primitive doesn't care about hedges, the input vertex is not a boundary vertex in the primitive (or not a vertex at all), or vtx is at an end of a boundary (e.g. open polys).

Create the topological binding between preallocated vertex and primitive.
Release the given vertex. This is equivalent to deleting a vertex without modifying its topology attributes. In other words, the primitive doesn't use the vertex anymore, but the vertex stays wired to the primitive and to the point it was wired to. The intended use is with stealVertex methods, so that the same vertex can be aquired by another primitive, thus maintaining its offset number and attributes The return value is the vertex offset (same as input) if successful and GA_INVALID_OFFSET otherwise.

Some primitives can have common/shared data between different instances of the primitives. This method is invoked during the save process to save data. The method requires you to save two objects sequentially (the data is stored in a list) for each shared key:
If there are multiple shared data pointers, the array can continue with name/value pairs.
For example, you might have something like:
Then in the primitive JSON, you'd likely want to have two fields, one for the shared data pointer, the other for an expanded version of the data. The shouldSaveField() method would be something like:
Then the saveField() method of the primitive JSON would look something like:
During the loading process, you can just get the shared data from the load map.

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).

| void GA_Primitive::swapOffsetValue | ( | const GA_Defragment & | defrag | ) |
For defragmentation, we need to update the offset.
|
virtual |
This method is called when the vertex index map is being defragmented. Since the defragmentation process moves vertex offsets, primitives need to update their references with the new values.
