Ray-traced Mandelbox fractal:

![Example 1](https://raw.githubusercontent.com/kraglik/pyfractalexplorer/master/screenshots/mandelbox_1.png "Example 1")

## Controls:

W - forward

A - left

S - back

D - right

Space - up

Left CTRL - down

Q - push current speed to stack

E - restore speed from stack

Mouse - look

Mouse wheel up - increase zoom

Mouse wheel down - decrease zoom

Mouse wheel - set zoom to 1.0

left arrow - increase accuracy (lower epsilon, more details)

right arrow - decrease accuracy

up arrow - increase movement speed

down arrow - decrease movement speed

PageUp / PageDown - change fractal

LESS ( < ) / GREATER ( > ) - increase or decrease amplitude

T - enable time dependency (cos(time) * amplitude)

P - take screenshot

= / - to increase / decrease raymarcher iteration limit (regulates quality)

Esc - exit

## Available fractals

1. Mandelbox

2. Mandelbulb

3. Sierpinski Triangle

4. Menger Sponge
