Why does matrix T have four dimensions? I think when we talked about it in the previous lecture, we didn't add a fourth coordinate yet. Shouldn't it just be a 3*3 matrix representing a 3D transformation?

Are we immediately using the quaternion transformation for our input coordinates or is there another reason why the matrices are 4x4?

This assumes we have all our scene targets already described as triangles. But will we cover how to break down more complex polygons into triangles?

What does the 4th dimension represent in the transform matrix?
gfkang
is the 4x4 matrix because of homogenous coordinates? do we always just use dim + 1 for these kinds of applications?

When an .obj file is opened by a text editor, it has a whole list of vertices and more. Are they equivalent to the information here?
