// BuilderVertex, BuilderVertexI
|
|
//
|
|
// The basic class for passing vertex values to the builder. See the
|
|
// comments at the beginning of builder.h and builderPrim.h.
|
|
//
|
|
// Like BuilderPrim, the BuilderVertex and BuilderVertexI classes are
|
|
// actually two different instantiations of the same template class,
|
|
// BuilderVertexTempl. The difference is in the types of the
|
|
// attribute values for the four kinds of attributes: vertices
|
|
// (coords), normals, texture coordinates, and colors. BuilderVertex
|
|
// specifies Coordf, Normalf, TexCoordf, and Colorf for each of these
|
|
// (actually, it's BuilderV, BuilderN, BuilderTC, and BuilderC, which
|
|
// are simply wrappers around the above types), while BuilderVertexI
|
|
// specifies ushort for all of them.
|
|
//
|
|
// It is this templating that drives the whole indexed/nonindexed
|
|
// support in this package and in the mesher. The two kinds of
|
|
// BuilderVertex are designed to present largely the same interface,
|
|
// regardless of whether its component values are actual vector
|
|
// values, or simply index numbers. Lots of things, therefore, can
|
|
// template on the BuilderPrim type (which in turn termplates on the
|
|
// BuilderVertex type) and thus easily support both indexed and
|
|
// nonindexed geometry.
