BND is a binary version of the ASCII-based format used to define the boundary of PKG objects.
struct BBND { char version; // == 1 long nVertices; long nMaterials; long nPolys; BBNDVertex vertices[nVertices]; BBNDMaterial materials[nMaterials]; BBNDPolygon polys[nPolys]; }; struct BBNDVertex { float x; float y; float z; }; struct BBNDMaterial { char[32] name; float elasticity; float friction; char[32] effect; char[32] sound; }; struct BBNDPolygon { short indicies[4]; short material; };
Bound polygons can be quads and triangles. If a polygon is a triangle, the last index is 0. Therefore a future exporter must never put the vertex index 0 last in a quad polygon. All strings are fixed 32 byte arrays with terminator byte 0x00.
