I see it clear now, so there were actually typos in the paragraph. With the comments you added looks pretty much to what I was understanding with the example provided.

comment Is the statement in Scratchapixel about transforming points correct?
The texts passages are the two I quoted in my question. To me the example says Pworld = Plocal * M which is ok to me. However, the text quoted, seems (at least for me) saying Pworld = Plocal * inv(M), i.e. "If we transform a point P whose coords are defined w.r.t. to local-coord system with the inverse of M, we get the coords of P w.r.t. world-coord system" or paraphrasing "A point P in local-coord system, transformed with the inverse of M, gives the point P in woord-coord system". I think it should be "A point P in local-coord sys, transformed with M, gives the point P in woord-coord sys"

comment How to calculate reflection vector from point sprite sphere?
I am just learning about point-sprites and OpenGL in general. Even if we can cheat with the point-sprite spheres, how should I do it to account for the perspective projection? Do you know a good source that walk you through this?

So the position in the surface is sphereOrigin + N * sphereRadius? The sphereOrigin is the vertex that is the input in the vertex shader?
