| 26 | * <p>Notice that \c TriangleFunctor is a class template, and that it inherits |

| 29 | * v3, bool treatVertexDataAsTemporary)</tt>, which will be called for every |
|---|
| 30 | * triangle when the functor is applied to a \c Drawable. Parameters \c v1, \c |
|---|
| 31 | * v2, and \c v3 are the triangle vertices. The fourth parameter, \c |
|---|
| 32 | * treatVertexDataAsTemporary, indicates whether these vertices are coming from |
|---|
| 33 | * a "real" vertex array, or from a temporary vertex array, created by the \c |

| 34 | * TriangleFunctor from some other geometry representation. |
