1.构造一个平截台体（Frustum）最近距离=-projMatirx.43/projMatrix.33projMatrix。33 =深度/（深度-最近距离）projMatrix。44=-最近距离*（深度/（深度-最近距离））FrustumMatrix = projectionMatrix*viewMatirx；FM=FrustumMatrix；//最近面m_planes[0].a = FrustumMatirx._14 + FrustumMatirx._13; m_planes[0].b = FrustumMatirx._24 + FrustumMatirx._23; m_planes[0] 阅读全文
