- [x] Embedded: single-file header, all dependencies included.
- [x] Embedded: [single-file header](engine/joint/fwk.h), all dependencies included.
- [x] Compiler: MSVC, MINGW64, TCC, GCC, clang, clang-cl and emscripten.
- [x] Linkage: Both static linkage and dynamic .dll/.so/.dylib support.
- [x] Platform: Windows, Linux and OSX. Partial HTML5/Web support.

## Roadmap ᕕ(ᐛ)ᕗ (in order of arrival; ✱: partial support)
- [ ] AI pass: actors, waypoints, pathfinding, behavior trees (h/fsm,goap), and navmesh generation.
- [ ] Render pass: reverse-Z, automatic LODs, impostors, decals.
- [ ] Materials: (colors✱, textures✱, matcaps✱, videos✱, shadertoys✱). Shadertoys as post-fx✱. <!--materials as postfx, as they have an update() method -->
- [ ] Lighting: Hard/soft shadow mapping (VSM,CCSM). Baked lightmaps. Refl probes. Integrated PBR.
- [ ] Network/VM pass: Entity/component/systems and worlds. <!-- W/ECS, gameobj, serialization:load/save/merge, diff/patch ;; dead reckoning, interpolation, extrapolation, bandwidth budgets -->
- [ ] Core pass: struct serialization.
- [ ] Message pipeline and replication. <!-- manual/replication channels, node sharding/clustering. -->
- [ ] Digital signals, message buffering and event polling.
- [ ] World streaming and level loading.
- [ ] Scenegraphs and spatial partioning. BVH, PVS, occluders, frustum culling.
- [ ] Server/client architecture. Hybrid P2P.
- [ ] NAT traversal. Socketless API, message API and pub/sub wrappers (enet/websocket).
- [ ] Editor pass = netbased + offline rendering + virtual input.
- [ ] Basic: Gizmos✱, scene tree, property editor✱, load/save✱, undo/redo✱, copy/paste, on/off (vis,tick,ddraw,log), vcs.
- [ ] Scenenode: node singleton display, node console, node labels, node outlines✱.<!-- node == gameobj ? -->
- [ ] Debug: toggles on/off (billboards✱, materials, un/lit, cast shadows, wireframe, skybox✱/mie✱, fog/atmosphere, collide✱, physics).
- [ ] Level: volumes, triggers, platforms, level streaming.
- [ ] Sub-editor: timeline and data tracks, node graphs. <!-- worthy: will be reused into materials, animgraphs and blueprints -->
- [ ] Sub-editor: Procedural content, brushes, noise and CSG.
- [ ] Sub-editor: blendshapes, additive anims, head/foot/hand IKs.
- [ ] Script pass: DLL✱ (module->plugin/sys), Lua✱, Luajit✱, Teal✱ and TypeScript.
- [ ] Render pass: reverse-Z, automatic LODs, impostors, decals.
- [ ] Materials: (colors✱, textures✱, matcaps✱, videos✱, shadertoys✱). Shadertoys as post-fx✱. <!--materials as postfx, as they have an update() method -->
- [ ] Lighting: Hard/soft shadow mapping (VSM,CCSM). Baked lightmaps. Refl probes. Integrated PBR.
- [ ] Tools pass
- [ ] Extend shaders + bindings. Per-platform✱, per-type✱, per-asset options. GIF, PKM.
- [ ] Extend atlas (sprite/lightmaps). Fit packing (sprites).
- [ ] Extend bindings and messaging: parse C headers during cooking stage. <!-- msgs,docs,refl,meta,lua -- (*.c, *.h) as .proto/.pbc maybe, free reflection+automatic bindings -->
- [ ] API pass
- [ ] Extend math: quat2, bezier, catmull.
- [ ] Discuss API and freeze it.
- [ ] Document everything.

## Quickstart
- Double-click `MAKE.bat` (Win) or `sh MAKE.bat` (Linux/OSX) to quick start.
- `MAKE.bat all` (Win) or `sh MAKE.bat all` (Linux/OSX) to build everything.
- `MAKE.bat proj` (Win) or `sh MAKE.bat proj` (Linux/OSX) to generate solutions/makefiles.
- `MAKE.bat help` (Win) or `sh MAKE.bat help` (Linux/OSX) for a bunch of options.
- `MAKE.bat hello.c` (Win) or `sh MAKE.bat hello.c` (Linux/OSX) to build a single executable.

## Cook
- Most asset types need to be cooked before being used in your application. Some other assets like `.png` do not.
- Cooked assets will be written into .zipfiles close to your executable, and mounted before entering game loop.
- Cooked .zipfiles and your executable are the only required assets when releasing your game.
- Cook manually your assets by invoking supplied [`tools/cook` standalone binary](tools/).
- Cook automatically your assets by just playing your game: a runtime cook is already embedded into your binary.
- In order to achieve this, ensure the [`tools/` folder](tools/) is close to your executable.
- This folder contains all the related binaries to perform any asset conversion plus the [cookbook](tools/cook.ini) to do so.
- Assets need to be cooked before being consumed in your application. The [tools/](tools/) folder contains all the related binaries to perform any asset processing plus the [cookbook](tools/cook.ini) to do so.
- Your game will cook all your assets as long as the [`tools/`](tools/) folder is next to your executable. Alternatively, cook them all just by invoking supplied [`tools/cook` standalone binary](tools/).
- In both cases, assets will be cooked and packed into .zipfiles next to your executable, then mounted before entering game loop. These .zipfiles plus your executable are the only required files when releasing your game.
## Extra tips
- Any ico/png file named after the executable name will be automatically used as app icon.
- Similar to the ico/png case above, the cooked .zipfiles can be named after the main executable as well.
- Dropped files into game window will be imported & saved into [`import/`](art/engine/import) folder.
- Update the gamepad controller database by upgrading the [`gamecontrollerdb.txt`](art/engine/input) file.
- Depending on your IDE, you might need to browse to [`split/`](split/) sources when debugging FWK.
- Dropped files into game window will be imported & saved into [`import/`](engine/art/import/) folder.
- Update the gamepad controller database by upgrading the [`gamecontrollerdb.txt`](engine/art/input/) file.
- Depending on your IDE, you might need to browse to [`engine/split/`](engine/split/) sources when debugging FWK.
- Cook assets on demand, as opposed to cook all existing assets on depot, by using `--cook-on-demand` flag.
- Linux/OSX users can optionally install wine and use the Windows tools instead (by using `--cook-wine` flag).
- Disable automatic cooking by using `--cook-jobs=0` flag (not recommended).
- Generate a project solution by dropping `split/fwk.h, fwk.c and fwk` files into it.
- Generate a project solution by dropping `engine/fwk.h, fwk.c and fwk` files into it.
- Auto-generated Luajit and Python bindings can be found in the [`engine/bind/`](engine/bind/) folder.
<!-- - On windows + vc, you can use `make bindings` or `make docs` to generate everything prior to a release -->
<!-- - Note: Windows: Assimp.dll may need [this package installed](https://www.microsoft.com/en-us/download/confirmation.aspx?id=30679).-->

/*
Believable animated volumetric dust storm in 7 samples,
blending each layer in based on geometry distance allows to
render it without visible seams. 3d Triangle noise is
used for the dust volume.
Also included is procedural bump mapping and glow based on
curvature*fresnel. (see: https://www.shadertoy.com/view/Xts3WM)
Further explanation of the dust generation (per Dave's request):
The basic idea is to have layers of gradient shaded volumetric
animated noise. The problem is when geometry is intersected
before the ray reaches the far plane. A way to smoothly blend
the low sampled noise is needed. So I am blending (smoothstep)
each dust layer based on current ray distance and the solid
interesction distance. I am also scaling the noise taps as a
function of the current distance so that the distant dust doesn't
appear too noisy and as a function of current height to get some
"ground hugging" effect.

/*
There are two main hurdles I encountered rendering this effect.
First, the nature of the texture that needs to be generated to get a believable effect
needs to be very specific, with large scale band-like structures, small scale non-smooth variations
to create the trail-like effect, a method for animating said texture smoothly and finally doing all
of this cheaply enough to be able to evaluate it several times per fragment/pixel.
The second obstacle is the need to render a large volume while keeping the computational cost low.
Since the effect requires the trails to extend way up in the atmosphere to look good, this means
that the evaluated volume cannot be as constrained as with cloud effects. My solution was to make
the sample stride increase polynomially, which works very well as long as the trails are lower opcaity than
the rest of the effect. Which is always the case for auroras.
After that, there were some issues with getting the correct emission curves and removing banding at lowered
sample densities, this was fixed by a combination of sample number influenced dithering and slight sample blending.
N.B. the base setup is from an old shader and ideally the effect would take an arbitrary ray origin and
direction. But this was not required for this demo and would be trivial to fix.
