Baa Fuzzpaint

A graphics-accelerated digital art software combining the ease-of-use of raster with the lossless quality of vector.



**This project is in heavy development**, many features are in-progress and semver is ignored. Notably, **drawings cannot yet be saved** - but you can doodle to your heart's content!



## Goals

* Fast, efficient, and instant to launch even on low power hardware.

* A workflow that serves everything from quick jotting down of ideas to detailed artworks.

* No choice is set in stone - change brushes, resolution, and colors retroactively in your work.

* Every edit is lossless and undo-able, even after you close the program - files include their entire undo tree.

* Small, portable, self-contained document files (for people like me who save every doodle!)

* In an error, unsaved changes should never be lost - losing user work is unacceptable!

* Resources are viral - take and use the brushes, textures, effects, fonts, etc. found in drawings you've downloaded.

* A modular application design allowing CLI, headless servers, and graphical clients to all share the same codebase.



### Dreams

* Optional Client/Server system allowing realtime collaboration.



### Non goals

* Image editing - though this project aims to provide my ideal digital art creation environment over traditional raster software, it does not aim to implement the other functions of a raster image editor.

* Vector design - Despite it's vector nature, Fuzzpaint does not aim to provide precise control over curves and is instead intended for freeform hand-drawn artwork.



## Building

Requires the [most recent Rust *nightly* toolchain](https://www.rust-lang.org/tools/install). Clone and execute `cargo +nightly run --release` from within the root directory of this repo!



## Platform Support

This app is cross platform and should run on any device that meets the [current vulkan requirements](assumptions.md).

(if your device doesnt work - even if it's because of these requirements - please file an issue!).



For tablet support, see the [octotablet](https://github.com/Fuzzyzilla/octotablet) sister project.



# Road to **0.2.0**

To declare **0.2.0**, I would like to be able to freely doodle a thing and save it to disk. We're getting dangerously close!



 - [ ] File I/O

   - [ ] Read/Write [custom vector image format](fileschema.md)

   - [ ] Write file history

   - [ ] Export common image formats

     - via image-rs/image

   - [X] [Shell integration](https://github.com/Fuzzyzilla/fuzzpaint-thumbnailer)

 - [ ] Brushes

   - [ ] Make and manage textured brushes from inside fuzzpaint

   - [ ] Save brushes to file

     - To document or to global repo? - resolved: both, with ~~UUIDs~~ cryptographic hashes! That way, files can be freely shared, and brushes can be easily re-used.

   - [X] Tesselation engine capable of mixed brushes

   - [X] Stamped brushes

   - [X] Efficient erasers

 - [ ] Layers

   - [X] Simple UI to manage layer creation, order, modes, etc.

   - [X] Blending shaders

     - fall forward on `EXT_blend_operation_advanced` or `EXT_fragment_shader_interlock`?

   - [X] Passthrough, grouped-blend layers

   - [X] Color fill layers

   - [ ] Text layers

   - FX + other self-populating layers (clone, gradients) come later

 - [ ] UI

   - [X] Initial layout

   - [X] A ~~simple~~ **✨robust and rebindable✨** hotkey system, with support for

         pen and pad buttons (although, pen+pad events are not yet wired up)

   - [X] Application settings menu

   - [X] Infinite Undo/Redo

   - [X] Pan, Zoom, Scroll, Rotate

   - [ ] Mirror

   - [X] Fit, 100% modes

 - [ ] Editor

   - [ ] Color, Object Pickers

   - [ ] Select strokes

     - [ ] Select parts of strokes

   - [X] Transform layers

   - [ ] Transform strokes

   - [ ] Cut, Copy, Paste strokes (within program only)
