摘要: A method of real-time shadow generation in computer graphical representation a scene, the comprising defining an eye's frustum based on desired view scene; location light source illuminating at least portion generating trapezoid to approximate area, E, within post-perspective space light, L; applying trapezoidal transformation objects into for computing map; and determining whether object or part thereof is scene utilising computed map.
