Pretty simple, I know. Shows off some basic texturing and per-pixel lighting, but that's about all I got for now. Currently this is all done in OpenGL, but I've abstracted many of the concepts in such a way so that I could easily swap in a DirectX renderer. This is done at compile-time though, so that I avoid dealing with dynamic libraries.
It's pretty easy to get something up and running too. I just extend an application class, which takes care of some nitty gritty details for me (e.g., the game loop). With the help of some compile-time polymorphism, I just override three methods: initialize, update, and render. Also, input handling (keyboard + mouse) is currently implemented using mappings to boost::functions. These mappings are registered at runtime, generally in the initialize method one specifies.
There's plenty of work to be done, but I think it's a good start. Some things I need to work on:
- Resource Management. Currently all resource management is done through boost:shared_ptr. In other words, there isn't really any "management" happening. I need some form of a manager that can load various assets, caching things as necessary to help with efficiency.
- Higher-level Primitives. Currently I send triangle primitives to the renderer, which is a little too low level for my liking. I'd like to pick a set of base primitives that are at a higher-level (e.g., triangular mesh, model, terrain)
- Deferred Rendering. I've always wanted to take a stab at implementing deferred rendering. I'd just love to play around with shaders in general and getting some fancy stuff on the go.
Of course, there's a lot more than that -- Terrain LoD, Character Animations, GUI Rendering, Game Logic, Physics, etc -- but it's a start!
