@ @ Greetings. I know that VXGI still has problems with smooth reflections but I wanted to notify you about :
On the Ball , the reflections of the mannequin is flickering even when he deosn’t move. I can also see many voxels of the the edged of the reflected emissive balls. and from certain angles I see voxels in circles inside the reflected balls: ://imgur/a/jKonA
But what bothers me the most is that the Colour bleeding and mixing don’t work in most of the cases. I expected to get results like these : ://www.enchantedlearning/crafts/Colormixing.shtml
Well only red + green and and very little blue + green worked a tiny bit. The others didin’t work at all. I was expecting to get green on the wall after the colours mix : ://i.imgur/N8OYlJO.png?1 etc
Well few months ago, I used LPV and it gave me great results in colour bleeding and mixing and that chnaged even using time of day and from where the sun was facing the walls : ://imgur/a/VGQnS
Effectively colours do mix and the results are like : ://upload.wikimedia.org/wikipedia/commons/2/2c/Additive_color_mixing_simulated.png

I really hope VXGI will get to that level and we can see such colour bleeding and mixing. Thanks.
Color mixing should work fine, all the math in VXGI is additive in RGB space - and that is physically correct. Unless some saturation in the emittance map is involved, that is.
The page that you reference talks about color mixing in a different color space, like paint on paper. In RGB space, blue (0000ff) + yellow (ffff00) is white (ffffff) - and that’s what you get on that picture, multiplied by some small factor that makes output gray.
The RGB colour model is an additive color model in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
The main purpose of the RGB color model is for the sensing, representation, and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography. ...
