Introduction to CG 10:vertex Shader-geometric transformation-MVP matrix transformation

Unity built-in matrix type:
M: World Matrix V: Camera Matrix P: projection matrix T: Matrix TransposeIT: Reverse _object2world of Transpose: Model to World Matrix _world2object: World to model Matrix
MVP Matrix Transform: Shader Demo
MVP Transpose Transform: C # Demo
matrix4x4 MVP = Camera.Main .ProjectionMatrix * Camera.Main .Worldtocameramatrix * Transform .Localtoworldmatrix;The multiplication of matrices is sequential, and if it is not true, it is reversed to see the effect.
Finally, the MVP matrix is assigned to shader's MVP attribute, instead of the unity built-in UNITY_MATRIX_MVP matrix.
