|
// Description : The main grouping tool for BuilderPrims. See the
|
|
// comments at the beginning of builder.h.
|
|
//
|
|
// As each primitive is added to the builder, it is
|
|
// associated with a bucket. The bucket stores the
|
|
// scene-graph properties of the primitive, and is used
|
|
// to identify primitives that have the same properties
|
|
// and thus may be joined into a common triangle strip.
|
|
//
|
|
// This grouping is done via the ordering operator, <,
|
|
// which defines an arbitrary ordering for buckets and
|
|
// identifies those buckets which are equivalent to each
|
|
// other. By subclassing off of BuilderBucket and
|
|
// redefining this operator, you can change the grouping
|
|
// behavior to suit your needs, if necessary.
