The btScalar type abstracts floating point numbers, to easily switch between double and single floati...
btScalar dot(const btVector3 &v) const
Return the dot product.
int bt_plane_clip_triangle(const btVector4 &plane, const btVector3 &point0, const btVector3 &point1, const btVector3 &point2, btVector3 *clipped)
Clips a polygon by a plane.
