fractal_viewer's Introduction

Fractal Viewer!

This is a prototype! A version written in Rust using gfx-rs along with compute shaders for better performance is eventually planned.

I made a WebGL based version here. See the code here

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.

Running the program

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.

Controls

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

Experiment on your own

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.
