Member Data Documentation

SmallArray<Face, 6> G3D::Frustum::faceArray

The faces in the frustum. When the far plane is at infinity, there are 5 faces, otherwise there are 6. The faces are in the order N,R,L,B,T,[F].

SmallArray<Vector4, 8> G3D::Frustum::vertexPos

The vertices, in homogeneous space. The order is that of the near face, starting from the (object space) +x,+y corner and proceeding CCW from the camera's point of view; followed by the far face also in CCW order.

If w == 0, a vertex is at infinity.
