- // This particular set of vertices "gNormalizedVertices" and corresponding
- // facets "gaiFacets" describe a normalized cube centered about the
- // origin ([0,0,0] in 3-space). The gaiFacet array is made up of a series
- // of indices into the array of vertices, each describing an individual
- // facet (eg. a polygon), and are separated by -1. Note that the facets
- // are decribed in COUNTERCLOCKWISE (relative to the viewer) order so we
- // can consistently find the normal to any given facet. (The normal
- // is used to determine facet visibilty.)
