// RayLogo.ray - CoolRay Scene Description File
//
// This sample Scene demonstrates how a set of triangles
// can create a solid object. This is possible due to the
// special CSG alogirithm used in CoolRay. This allows even
// the usage of flat object like a Triangle to create solid
// primitives.
// A for loop is used to subtract 4 boxes from the pyramid
// and so creating a 'sliced' pyramid. Additionally a sphere
// is cut out of the pyramid.
