|
|
|
|
Vulkano is a Rust wrapper around [the Vulkan graphics API](https://www.khronos.org/vulkan/).
|
|
It follows the Rust philosophy, which is that as long as you don't use unsafe code you shouldn't
|
|
be able to trigger any undefined behavior. In the case of Vulkan, this means that non-unsafe code
|
|
should always conform to valid API usage.
|
|
|
|
What does vulkano do?
|
|
|
|
- Provides a low-levelish API around Vulkan. It doesn't hide what it does, but provides some
|
|
comfort types.
|
|
- Plans to prevent all invalid API usages, even the most obscure ones. The purpose of vulkano
|
|
is not to simply let you draw a teapot, but to cover all possible usages of Vulkan and detect all
|
|
the possible problems in order to write robust programs. Invalid API usage is prevented thanks to
|
|
both compile-time checks and runtime checks.
|
|
- Can handle synchronization on the GPU side for you (unless you choose do that yourself), as this
|
|
aspect of Vulkan is both annoying to handle and error-prone. Dependencies between submissions are
|
|
automatically detected, and semaphores are managed automatically. The behavior of the library can
|
|
be customized thanks to unsafe trait implementations.
|
|
- Tries to be convenient to use. Nobody is going to use a library that requires you to browse
|
|
the documentation for hours for every single operation.
|
|
|
|
Note that in general vulkano does **not** require you to install the official Vulkan SDK. This is
|
|
not something specific to vulkano (you don't need the SDK to write programs that use Vulkan, even
|
|
without vulkano), but many people are unaware of that and install the SDK thinking that it is
|
|
required. However, macOS and iOS platforms do require a little more Vulkan setup since it is not
|
|
natively supported. See below for more details.
|
|
|
|
## Development status
|
|
|
|
Vulkano is still in heavy development and doesn't yet meet its goals of being very robust. However
|
|
the general structure of the library is most likely definitive, and all future breaking changes
|
|
will likely be straight-forward to fix in user code.
|
|
|
|
## Documentation
|
|
|
|
To get started you are encouraged to use the following resources:
|
|
|
|
* The guide on [vulkano.rs](http://vulkano.rs/guide/introduction) - Starts with trivial compute
|
|
examples (~50 lines of code) then works up to rendering triangles and mandelbrots.
|
|
* The [vulkano-examples](https://github.com/vulkano-rs/vulkano-examples) repository - Includes
|
|
examples in the repo and also a list of projects that use vulkano.
|
|
* [docs.rs](https://docs.rs/vulkano) - Full Vulkano API documentation
|
|
|
|
## Setup
|
|
|
|
Vulkano uses [shaderc-rs](https://github.com/google/shaderc-rs) for shader compilation. Refer to shaderc-rs documentation to provide a pre-built libshaderc for faster build times.
|
|
|
|
Unless you provide libshaderc, in order to build libshaderc with the shaderc-sys crate, the following tools must be installed and available on `PATH`:
|
|
- [CMake](https://cmake.org/)
|
|
- [Ninja](https://ninja-build.org/) Is optional except when building with MSVC. It may speed up build time for libshaderc.
|
|
- [Python](https://www.python.org/) (works with both Python 2.x and 3.x, on windows the executable must be named `python.exe`)
|
|
|
|
These requirements can be either installed with your favourite package manager or with installers
|
|
from the projects' websites. Below are some example ways to get setup.
|
|
|
|
### windows-msvc Specific Setup
|
|
|
|
1. `rustup default stable-x86_64-pc-windows-msvc`
|
|
2. Install [Build Tools for Visual Studio 2017](https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2017). If you have already been using this toolchain then its probably already installed.
|
|
3. Install [msys2](http://www.msys2.org/), following ALL of the instructions.
|
|
4. Then in the msys2 terminal run: `pacman --noconfirm -Syu mingw-w64-x86_64-cmake mingw-w64-x86_64-python2 mingw-w64-x86_64-ninja`
|
|
5. Add the msys2 mingw64 binary path to the PATH environment variable.
|
|
|
|
### Windows-gnu Specific Setup
|
|
|
|
windows-gnu toolchain is not supported but you can instead cross-compile to windows-gnu from windows-msvc
|
|
|
|
Steps 1 and 2 are to workaround https://github.com/rust-lang/rust/issues/49078 by using the same mingw that rust uses.
|
|
|
|
1. Download and extract https://s3-us-west-1.amazonaws.com/rust-lang-ci2/rust-ci-mirror/x86_64-6.3.0-release-posix-seh-rt_v5-rev2.7z
|
|
2. Add the absolute path to mingw64\bin to your PATH environment variable. (This path needs to be before the msys2 path)
|
|
3. Run the command: `rustup default stable-x86_64-pc-windows-msvc`
|
|
4. Run the command: `rustup target install x86_64-pc-windows-gnu`
|
|
5. Install [Build Tools for Visual Studio 2017](https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2017). If you have already been using this toolchain then its probably already installed.
|
|
6. Install [msys2](http://www.msys2.org/), following ALL of the instructions.
|
|
7. Then in the msys2 terminal run: `pacman --noconfirm -Syu mingw64/mingw-w64-x86_64-pkg-config mingw-w64-x86_64-gcc mingw-w64-x86_64-cmake mingw-w64-x86_64-make mingw-w64-x86_64-python2 mingw-w64-x86_64-ninja`
|
|
8. Add the msys2 mingw64 binary path to the PATH environment variable.
|
|
9. Any cargo command that builds the project needs to include `--target x86_64-pc-windows-gnu` e.g. to run: `cargo run --target x86_64-pc-windows-gnu`
|
|
|
|
### Linux Specific Setup
|
|
|
|
Use your package manager to install the required dev-tools and vulkan drivers
|
|
|
|
For example on ubuntu:
|
|
```
|
|
sudo apt-get install build-essential git python cmake libvulkan-dev vulkan-utils
|
|
```
|
|
|
|
### macOS and iOS Specific Setup
|
|
|
|
Vulkan is not natively supported by macOS and iOS. However, there exists [MoltenVK](https://github.com/KhronosGroup/MoltenVK)
|
|
an open-source Vulkan implementation on top of Apple's Metal API. This allows vulkano to build and run on macOS
|
|
and iOS platforms.
|
|
|
|
The easiest way to get vulkano up and running with MoltenVK is to install the
|
|
[Vulkan SDK for macOS](https://vulkan.lunarg.com/sdk/home). There are [installation instructions](https://vulkan.lunarg.com/doc/sdk/latest/mac/getting_started.html) on the LunarG website.
|
|
|
|
On iOS, vulkano links directly to the MoltenVK framework. There is nothing else to do besides
|
|
installing it. Note that the Vulkan SDK for macOS also comes with the iOS framework.

|
Contributions are welcome! Feel free to submit pull requests.
|
|
|
|
Pull requests that fix bugs or improve documentation are likely to be quickly reviewed, while pull
|
|
requests that add features or change the API may be more controversial and take more time.
|
|
|
|
If your change adds, removes or modifies a trait or a function, please add an entry to the
|
|
`CHANGELOG.md` file as part of your pull request.

## Structure
|
|
|
|
This repository contains four libraries:
|
|
|
|
- `vulkano` is the main one.
|
|
- `vulkano-shaders` Provides the `shader!` macro for compiling glsl shaders.
|
|
- `vulkano-win` provides a safe link between vulkano and the `winit` library which can create
|
|
a window to render to.
|
|
- `vk-sys` contains raw bindings for Vulkan. You can use it even if you don't care about vulkano.
|
|
|
|
In order to run tests, run `cargo test --all` at the root of the repository. Make sure your Vulkan
|
|
driver is up to date before doing so.
