Detailed Description

An IntersectionInfo is the result of an Ray Request It contains a variety of information concerning the shape that was hit by a ray.

Shape, hit point in object coordinates, normal in object coordinates the ray, which caused th intersection, and the matrices are always contained. Hint, instanceInfo and id are only contained if a shape is hit that supports this kind of data (at the moment PolygonSet and MappedVertexAttributeShapeGL). The hint for a PolygonSet consisting of a single range of triangles is the triangle number, otherwise the range number as before. The id can be passed as idIterator per Vertex for appropriate shapes.
