While shaders know how to multiply matrices, the API in the OpenGL core profile does not manipulate matrices beyond setting them, possibly transposed, into uniform and per-vertex data to be used by your shaders. It is up to you to build up the matrices you want to use in your shader, which you can do with the included helper routines as described in the previous section.
You will want to be multiplying matrices in your application, before sending them to your shaders, for a performance benefit. For example, let’s say you need matrices to do the following transformations:
1. Move the camera to the right view: Translate and rotate.
2. Move the model into view: Translate, rotate, and scale.
3. Apply perspective projection.
That’s ...
