_Object2World:当前的模型矩阵,用于将顶点/方向矢量从模型空间变换到世界空间 _World2Object:_Object2World的逆矩阵,用于将顶点/方向矢量从世界空间变换到模型空间 UNITY_MATRIX_MV,在正交时(仅旋转),UNITY_MATRIX_T_MV就是它的逆矩阵。如果考虑统一缩放k,逆矩阵乘1/k。如果只变换方向矢量,取UNITY_MATRIX_T_MV...
float4 UnityObjectToClipPos(in float3 pos){ //先通过mul(_Object2World, float4(pos, 1.0)) 将顶点从模型空间转换到世界空间 //然后再通过UNITY_MATRIX_VP进行观察和投影变换,转换到裁剪空间 return mul(UNITY_MATRIX_VP, mul(_Object2World, float4(pos, 1.0))); } //Unity5.3.6及以上可用 v2f v...

就是unity_ObjectToWorld，那么这个矩阵的内容是什么呢，没错，就是这个模型相对于世界空间原点的缩放，...

原来手动乘以MVP矩阵,现用UnityObjectToClipPos()函数解决 -_World2Object矩阵名称更新 // Upgrade NOTE: replaced '_World2Object' with 'unity_WorldToObject' 老代码: fixed3 worldNormal = normalize(mul(v.normal, (float3x3)_World2Object));
