Real time SSS

This is my own algorythm, I take a front render and a back render of diffuse light and then i take a view space render of the front and back checking proximities of neighbouring pixels (making a circle of samples) and its basicly just a blur except i weight depending on the viewspace distance not just 2d hypotenuse difference on a flat plane, which is where a blur usually resides, only 2d. its a 3d blur, and ive tweaked it and powered it down a little so it works realtime, and i get 60 fps at a semi close distance, (but the video is pretty poor at 10fps i dont know how to record properly) the closer you get and the further it needs to scatter the more work it has to do.

Good work! looks really good. Congrats for your realtime butt butt butt

@ilhadosmacacos hey thanks, this algorythm is the way to do it, Ive read a few papers now (but I wrote this with reading nothing) and now I know how to get it to look even better, its a few more light transmitting dot products I think to get the light sharing more realistic! :) thanks

@rouncer81 What language did you use for programming this? i just know nothing about programming. Whats the average fps? i wonder how amazing it were going to look in an actual game.

@ilhadosmacacos Just ordinary direct x 9, you dont even need 10 for it, but the shader gets big. The video is terrible fps, but its alot better when your actually using it, you get about 30-60 fps depending on how many pixels it has to blend.

Very cool result. I am looking forward to the day soon approaching that I can see my SSS as i paint my SSS maps. Apparently the UDK shaders work in the same way as those in Mudbox making this theoretically possible right now.

That is incredible! keep it up!

The character I'm building now - jelly-fish like female character - would show case this well.

Let me know if you need a high quality model to show off your work and I'll gladly work with you...

video games NEED this!
