Graphics Pipeline questions Ortho projection

[shiftwik]

Hi I'm trying to learn 3D graphics using C++/MFC. I suppose the context of my questions don't really have to do with C++ perse but more linear algebra I guess. Please bear with me since I'm dumb as a rock. From my research the pipeline consists of projections/transformation "model (vertices)" -> World -> View Cube (or tho projection) -> screen. after I transform the vertices of the model to "world" and then project it to the "view cube" for clipping I then flatten the vertices in the desired axis. So if I wanted a 2d orthographic side view, I would set the Y coordinate to 0 in the matrix to flatten. Please see this graphic [^] My question is, do I then need to rotate the left vector space I flatten the object(s) on to a "front" vector space and then draw on the screen? thanks
