I've been working on a DirectX demo for a little bit and even though it seems pretty simple, it actually has quite a nice code back-end. Preview Video It currently uses inheritance between the models (one model is a player, one model is an enemy) and a Scene and Model Managers to hold the render data. Also there's a point light shader I programmed running as the main source for light. After taking that video I edited the code heavily to rely more upon the inheritance and to make the rendering code to work in some more correct areas. The next big things I'm looking at adding is a decent level model (to provide reference) and an ambient light shader to brighten up areas that aren't in the dark. If anyone has a good model I can use for the city let me know. Thoughts, comments, etc...? Post it here or on my blog and I'll respond (this post will be kind of like my interactive journal).
