rust-3d
=======
3D/2D library written in Rust.
Offering useful containers, structures and algorithms for 2D and 3D space.
Meant as basis for numeric algorithms, viewers, game engines, ...
Migration 0.29.0 -> 0.30.0
--------------------------
Note that the module structure changed. There's now only submodules for `io` and `impls`.
Also `prelude` was removed.
If you were using the prelude via `rust_3d::prelude::*;` you should now be able to just switch to
`rust_3d::*;`.
If you were using explicit paths such as `rust_3d::filters::combinators::FilterAll` you should now use `rust_3d::FilterAll`.
Note that `io` and `impls` are still part of the module path.
This should make future usage easier, but might be painful for existing users.
Tour
----
Here's a little overview of some of `rust-3d`'s features.
The snippets / names might not be up-to-date, so please check `tests/` for compiling examples.
### Proper error handling
No `.unwrap()` where it's not 100% safe.
### Strong / Smart Types
There's strong types for everything that might get mixed up easily.
This way e.g. ids of faces can't be mistaken for ids of vertices.
```rust
fn edges_of_face(&self, faceid: FId) -> Result<(EId, EId, EId)>;
```
There's also smart types which restrict the values they can hold.
This way distances can never be `< 0.0`, sizes can be enfored to be `> 0.0` etc.
```rust
Positive
NonNegative
```
### Generic Code Base
I try and keep all algorithms and types as generic as possible.
- Even rather basic types like `Is2D` are split into several versions: `IsEditable2D`, `IsBuildable2D`
- `IsMesh` is defined for any vertex type and any number of vertices / face
- There's traits for collections (no need to use `Vec`)
This makes it possible to require as little implementation work as possible if you want to use your own types.
### Combinators / Transformers
- Any `IsFilter<T>` can be combined via `FilterAND`, `FilterOR`, `FilterAny`, `FilterNegate`...
- Any `IsFilter<T>` can be transformed to work for any collection of `T`s (`IsFilterRandomAccessible`).
- `IsDirectionField2D` might be transformed to an `IsFilter<Is2D>`, which can then be transformed to an `IsFilterRandomAccessible<Is2D>`.
### IO
Any `IO` method is defined on traits, so if you implement these, you'll get read/write of different file formats for free.

Examples
--------
Please take a look at the tests in `tests/`. These will be up-to-date and compiling.
I might add extensive tutorials / examples / demo projects in the future.
