Now, considering this is a 3D engine and all (and I want to reinvigorate discussion in this section), I figured that this stage in development warranted some planning for assets for actually testing the renderer. After all, without 3D assets, we can't actually render any pretty pictures, now can we? And then there's stuff like collision and whatnot for when we actually get into physics and whatnot. What we need at this early stage, IMO: - A Sonic model, with proper animations - Basic level geometry Neither of these have to be fancy at all. The Sonic model could be pure crap, for all we. Pretty simple, right? Of course, we will have to test these in various model formats to make sure they work correctly, but baby steps. As we move along in development, we'll need more assets to test the engine and eventually showcase it, but that's a while off, yet.
