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!
