Well, i had an idea the other day to improve a reconstruction technique I worked on a while back, to reconstruct an image from a sparse data set, but now I manged to make the selection of the points to keep smarter, and well, guess the results speak for themselves. The idea is to use before tracing, to only trace on a few pixels. The reconstruction code is fairly light, so I should have little overhead. Most of the overhead will probably come from the lowered coherence, as the trace will be sparse, but considering that image only has about 20% of the originals pixels, and with GI i can probably push it to 10% or less, it should allow a really big boost, that will also allow me to trace more rays, and improve quality a lot. Plus the way it works makes trivial to apply temporal filtering, essentially doubling the number of rays for free.
So, forgive my lack of know-how on , but as well as being faster in terms of render-time, would algorithm make AHR more VRAM-efficient, or is it purely voxelisation density that impacts memory usage?
