AutoSDF

procedurally generated signed distance functions

this is a very GPU-intensive application. if it's running slow, be sure to reduce scale, sdf-length and/or color-length in settings.txt. On the other hand, if you have a good GPU:

• be sure to increase max-iterations to something like 100-200. It will look much nicer.
• I also recommend increasing sdf-length to get more interesting shapes.

controls

• move mouse to look around
• W,A,S,D/arrow keys to move forward/backwards/left/right + Q,E/PageUp,PageDown to move up/down
• R to create a new SDF - use this a lot! most SDFs are boring!
• Space to "unpause time" (start animating). Press space again to pause time, and shift+space to rewind time.
• [ and ] to go forwards and backwards in time
• 0 to reset location + time
• =/- (equals/minus) to expand/contract the surface (change the "level set" of the SDF you're looking at)
• Ctrl+C to copy SDF to clipboard, Ctrl+V to paste SDF from clipboard. On Linux if you close the application the clipboard contents will be lost (thanks a lot X11).
• F to go fullscreen
• F10 to take a screenshot (saved to a folder called screenshots). The SDF string is saved in the PNG file's metadata. If you open it with notepad, you'll see it towards the beginning of the file.
• Press Ctrl+Q to quit (or press escape and click the "quit" button)
• You can use Shift to move faster and Ctrl to move slower.

saving SDFs

if you get an SDF which looks cool, you can copy it with Ctrl+C, and save it somewhere/share it with your friends.

also a list of all SDFs you've generated is stored in scenes.txt.

cool SDFs

here are some cool SDFs i've found. take a look at them (using Ctrl+V) and especially try using minus/equals!
