duzenko 674 Posted May 16, 2020 Report Share Posted May 16, 2020 This is my experiment in progress, analytical shadows The idea behind it is upload scene geometry for fragment shader to analyze it for shadow volumes It's terribly slow. My 1650s can only do 200 triangles in 4K It's also not clear how to soften it properly. I'm doing pixel noise but adding an average loop is a sure way to slow things down even more. Screen space average? https://github.com/duzenko/shadows2020 Quote Link to post Share on other sites

If split by a surface, its halves are shining both ways But yeah, with closed 3d shapes this should not happen P.S. you might want to check what you copy paste from the image hosting sites.

nbohr1more 2268 Posted April 25 Report Share Posted April 25 Nice work! Here is a stochastic approach for shadow maps for comparison: https://cg.ivd.kit.edu/publications/2015/sssm/StochasticSoftShadows.pdf  1 Quote Please visit TDM's IndieDB site and help promote the mod: http://www.indiedb.com/mods/the-dark-mod (Yeah, shameless promotion... but traffic is traffic folks...)
