Interactive editing of basic distance field operation
- power 11y agoFor anyone wondering what distance fields are for, check out: http://iquilezles.org/www/articles/raymarchingdf/raymarchingdf.htm http://iquilezles.org/www/articles/raymarchingdf/raymarching... The code to generate all those images comes to only 13k. There's a simple tutorial for modelling with distance fields on the same site: http://iquilezles.org/www/articles/distfunctions/distfunctions.htm http://iquilezles.org/www/articles/distfunctions/distfunctio... If you're into this kind of thing it's worth exploring that site.
- iamwil 11y agoDid anything change that made this possible that it wasn't possible before? Was it just that we have faster computers now? Or something else?
- bhouston 11y agoSigned distance fields have been used in VFX since the mid-1990s. One of the first paper formalizing its editing techniques was by Ken Museth in 2002: http://diyhpl.us/~bryan/papers2/frey/applications/Museth%20K.,%20Level%20set%20surface%20editing%20operators.pdf http://diyhpl.us/~bryan/papers2/frey/applications/Museth%20K... My contribution to the field (in collaboration with Ken, the author of the above) is making these scalar volumetric representations more scalable via using a recursive hierarchical sparse representation: https://www.cs.ubc.ca/nest/imager/tr/2006/Batty_HRLE/ https://www.cs.ubc.ca/nest/imager/tr/2006/Batty_HRLE/ Ken Museth is now the head of R&D at Dreamworks Animation and picked up a Sci Tech Oscar two years for his level set work: https://www.youtube.com/watch?v=5FwOc4OSOR0 https://www.youtube.com/watch?v=5FwOc4OSOR0
- zellyn 11y agoPretty nice. Is there any way to see/edit the tree of previously "applied" primitives?
- zellyn 11y agoI really like the SDF visualization in this tutorial: https://youtu.be/s8nFqwOho-s?t=12m https://youtu.be/s8nFqwOho-s?t=12m
- fla 11y agoVery nice ! I think it would be great to have the max iterations as an option as well ;)
