Instead, we can use SDL2's cross-platform audio +API and implement all the audio mixing directly in Scheme. +** TODO [#A] Ditch the readline dependency +Figure out how to get back to using Guile's built-in REPL for +=chickadee play= so the custom can go away. Readline is hard to make +work in an async manner. +** TODO [#B] Dedicated audio thread +Allow use of (ice-9 futures) for parallelism? +** TODO [#B] Texture fills for vector paths +** TODO [#B] Even-odd rule fills for vector paths +Right now only the non-zero rule is supported. +** TODO [#B] Add shear transformations to vector paths +** TODO [#B] Dashed lines for stroked vector paths +** TODO [#B] Mitered corners for stroked vector paths +** TODO [#B] Text rendering for vector paths +** TODO [#B] Add screenshots to manual +** TODO [#B] Improve particle system +Allow more settings to be modified.

Support +for other formats can be added later. This will give us more +flexibility since we won't be tied to SDL surfaces and thus a single +thread for image loading. +** DONE [#A] Fix keyboard layout bug +For example, someone with a QWERTZ keyboard layout, when they press +their Z key, will invoke the key-press handler with the Z key, but +(key-pressed? 'z) will be false and (key-pressed? 'y) will be true. +** DONE [#B] Quadtree spatial partitioning +** DONE [#B] Add arc-to procedure for vector paths +** DONE [#A] Tests for (chickadee data array-list) +** DONE [#A] Tests for (chickadee data heap) +** DONE [#A] Tests for (chickadee data queue) +** DONE [#A] Update rendering engine docs +** DONE [#A] Update live coding section of manual +** DONE [#A] Document polygon, cull face, depth test, stencil modes +** DONE [#A] Document cube map texture procedures +** DONE [#A] Document materials, lights, and meshes +** DONE [#A] Add intensity field to lights +** DONE [#A] Test suite +** DONE [#A] Binary bundles for Linux +For easy distribution of builds so players don't have to build +anything from source. +** DONE [#A] Mipmapping +** DONE [#A] Skyboxes +** DONE [#A] Basic 3D shape primitives +Plane, tesselated plane, sphere, cube +** DONE [#A] Image based lighting for 3D models +Cube maps and such.

Especially so for anything that does +vertex buffer streaming like sprite batches and vector paths. Maybe +copy something like guile-opengl's packed structs. +** DONE [#A] Front/back face culling support +** DONE [#A] Vector graphics rendering +Like NanoVG. +** DONE [#A] Feature request: Support color keyed tilesets in Tiled maps +** DONE [#A] Bug fix: Clear screen even when nothing is being drawn +** DONE [#A] Allow user to manipulate the current window +** DONE [#A] OBJ model loader and renderer +** DONE [#A] Fix bugs/missing features in particle renderer +** DONE [#A] Document how to hook up cooperative REPL server +** DONE [#A] Document (chickadee graphics tiled) module +** DONE [#A] Add pixel x,y to tile x,y procedure for Tiled maps +** DONE [#A] TrueType font rendering + Like love2d or NanoVG +** DONE [#A] Chickadee executable +Like love2d's =love= executable. For getting new users up and running +quickly. +** DONE [#B] Linear/radial gradient fills for vector paths +** DONE [#B] Improved blending API +Rather than using symbols to represent some predefined blending modes, +create an api that supports the full range of options that OpenGL +provides for defining the blending function. +** DONE [#B] Tile map scrolling +** DONE [#B] OpenAL sound +Better than SDL_mixer. For love2d parity. +** DONE [#B] glTF 2.0 asset loading +Partially implemented but most example models don't render correctly. +** DONE [#C] Rewrite GPU state and render context code +Adding a new piece of state requires too much work, much of which +feels redundant. +** DONE [#C] Improve technique-specific state handling +Right now everything (shaders, buffers, etc.) is wrapped in 'delay' +forms and then 'force'd when rendering. It would be better if we +could somehow register this stuff with the gpu object. A plugin +system, maybe. The plugins would be initialized when the gpu object +is created and all the state would live there instead of at the +top-level of various modules. +** DONE [#C] Physically based rendering +Needed for full glTF rendering support but just good in general for +3D. |
