Perhaps it could use some + syntactic sugar for all of the "call-with-foo" forms. Also, a + naming convention needs to clearly differentiate procedures/macros + in the imperative API from those in the high-level API. + Originally, I didn't expect users to really ever have to use the + imperative API, but the introduction of sprite batches has made me + realize that writing custom low-level rendering routines will be + common enough to merit a nice API. + +** TODO Allow modules to declare state via signals, including OpenGL resources + This is a tricky one. The major headache with my Lisp Game Jam + attempt was that the signal framework had to be abandoned + *everywhere* except the top-level environment of the script that + starts the game loop. The reason for this was that the game state + typically required that the SDL window was opened and the OpenGL + context was available in order to work. Thus, at the top-level, we + first had to open a window and only then could we define signals. + The goal here would be to eliminate this major restriction so that + a game can be factored into many Guile modules and still declare + time varying state with signals. One important consequence here is + that all OpenGL resources *must* be declared as signals that wait + for the game loop to start before loading. + +** TODO Use a single OpenGL resource guardian structure + This will deduplicate code amongst all Scheme data types that wrap + OpenGL resources, because right now each one uses its own separate + guardian. + +** TODO Separate vertex arrays from meshes + Currently, a mesh is a vertex array. This is bad because vertex + arrays are useful in situations where the static mesh abstraction + isn't a good fit, such as with sprite batches. Therefore, a vertex + array should have its own dedicated data type that both meshes and + sprite batches use in their respective implementations. + +** TODO inotify-based live reloading + Better than periodically making 'stat' calls in a loop. + +** TODO Pure Scheme 4x4 matrix multiplication implementation + Guile 2.1.2's float unboxing optimizations should enable this to be + both fast and not allocate so much.
