An interactive visualization of a random vector fields

Vector Field Noise Visualizer

A visualizer to see what kinds of shapes different noise algorithms make.

The noise algorithms demonstrated are:

• Heterogenous Multifractal Noise
• Billowy Noise
• Checkerboard Noise
• Fractal Brownian Motion Noise
• Hybrid Multifractal Noise
• Open Simplex Noise
• Perlin Noise
• Value Noise
• Worley Noise

Running The Visualizer

You'll need to have Rust and cargo installed. Then, run cargo run --release in you terminal of choice.

Controls

key	what it does
N and B	Cycle forward and back through Noise types
J and K	Cycle forward and back through Visualizer types
+ and -	Zoom in and out by changing the "scale" of the noise
] and [	Speed up or slow down the rate of change
Arrow Keys	Move around by offsetting generated noise
O	Reset your offset back to the origin
R	Reset speed, scale, and offset
H	Show or hide the help screen
R	Reset everything
H	Show or hide this help screen
X	Render the current vectors to an SVG
Esc	Quit and return to the desktop

For SVG export to work, you must set the SVG_EXPORT_DIRECTORY environment variable to a valid directory.
