[Feature Request]顶点法线的调整

顶点法线的调整
顶点法线就是顶点的方向。3D图像中的光照计算需要光源的方向,视线的方向,面的朝向(法线方向)三个参数。也就是会通过法线方向的调整,控制阴影的外观。

《罪恶工具:X标记》的角色模型有4万面。如果什么都不做,模型会产生复杂的阴影。不过开发者想要的是赛璐璐动画那样大片,概括的阴影。所以在维持3D模型精度的同时,将多边形的方向信息进行调整,扩大光照产生的阴影。

比如把脸颊附近的法线调整到和鬓角处接近,在鬓角变暗的时候,脸颊附近也会变暗。通过法线调整实现了让高精度模型拥有低精度模型的概括阴影。

这里的实现方法是给syToons增加一个法线贴图的选项,使用连入的额外的法线贴图,改变顶点的法线。
