In OpenGL, if you want to manipulate the model, it is necessary to multiply the state of the model (the current matrix) by a matrix corresponding to this operation.If multiplied by the transformation matrix (translation, scaling, rotation), the position of the model is transformed after multiplying;If multiplied by a projection matrix (projecting a 2D plane), the projection of the model is set when multiplied;If multiplied by the texture matrix (), the texture mode of the model is set. And to sp
