height=270 src="http://www.tuyasoft.com/image/engine_9.jpg" width=396 border=0>&nbsp; <BR><BR><BR>阴影系统： <BR>人物的影子使用的是PlanarShadow，地形阴影应该也是预先用PlanarShadow渲染得到的。 <BR>建筑物的SelfShadow让人印象深刻，我想应该是用ShadowMapping预渲染得到结果，然后再变换到TextureSpace中并保存下来。 <BR><IMG height=270 src="http://www.tuyasoft.com/image/engine_18.jpg" width=396 border=0> <BR><IMG height=270
