This is a prototype! A version written in Rust using gfx-rs along with compute shaders for better performance is eventually planned.
This simple renderer uses GLSL accelerated Ray Marching and a host program written in the Processing language to display fractals.
It can render any fractal which can be defined with a signed distance function (SDF).
Right now only some fractals defined with IFS are present by default.
Install Processing if you haven't already and run the program as any other Processing sketch.
You can also download the prebuilt binaries located in releases.
| key sequence | action |
|---|---|
| right/left arrow | switch between fractals |
| drag mouse | rotate the fractal |
| drag mouse + L | change the light direction |
| drag mouse + R | rotate the camera |
| drag mouse + P | change the orientation of the cut plane |
| scroll | zoom in and out |
| scroll + shift | zoom in and out (slower) |
| scroll + I | change the number of iterations |
| scroll + R | change the number of reflection bounces |
| scroll + P | change the position of the cut plane |
| scroll + P + shift | change the position of the cut plane (slower) |
| S | reload shader |
| C | save screenshot |
You can modify the shader to change the color and other attributes. Hit the S button on your keyboard once the program is running to reload the shader.
You can also add your own fractals just by adding another file inside the fractals folder.
