An attempt at porting Inochi2D to Rust.
How it came to be:
Inox2D is currently a bit of a merge between the original Inochi2D implementation in D and Link Mauve's implementation in Rust (the inochi2d crate). The original is the standard, while Link's is a reverse-engineered and optimized implementation, but lacking the remaining core features that need to be implemented. His code is much simpler, but also not extensible (nodes are managed with an enum), so users of the library wouldn't be able to create custom nodes.
Inox2D is designed to be extensible. Nodes are extensible through the Node trait and users can create their own NodeRenderer with the opengl feature. That means a lot of cursed code involving dyn Trait, Any and trait downcasting. Hopefully in a future version of Rust I'll be able to make these abstractions cleaner with the Provider API (I prefer to stay on the stable version of Rust).
Update: I'm currently rewriting the node system to be much cleaner. The Node trait will likely disappear in favor of just Any.
Note: all the shader files that are present in this repository (under
shaders/) have been copied from the original Inochi2D implementation, but are currently not used. Instead, it's using Link Mauve's simpler shaders.
| Implementation | language | OpenGL calls |
|---|---|---|
| Inochi2D standard | D | 3076 |
| Link Mauve's inochi2d | Rust | 551 |
| Inox2D | Rust | 634 |
To be honest, the lack of features is probably the major reason for the small number of calls.
The model is parsed and rendered correctly!
However, it's the only thing that works currently. It doesn't deform, doesn't have physics, and doesn't support animations.
- Rendering (at least for the two example models)
- Deform
- Physics
- Animations
I may attempt to rewrite the OpenGL rendering code to be on-par with the standard Inochi2D implementation.
