- Two cubes side-by-side sharing a face (just one!) where they touch. This is non-manifold but to many "it seems clear" that the face that is inside the two cubes is inside, so a self-union…
Ember might be faster than Manifold huge models, because it pays more attention to short-circuiting around large parts of models that are unaffected by intersection. But this is just a…
One last small update - we just got some feedback that it's very useful to have analytical inverses for tone mapping functions. Ours was difficult to invert, but with a tiny change, it becomes…
Okay, I've improved the OCIO approximation by extending to lower values that cover the low end of sRGB better. Of course it could be further improved by increasing the resolution of the LUT, but I…
@jorn Thank you for the detailed analysis! You're absolutely correct about the tradeoffs vs Standard, and thanks for the excellent test image showing the errors in my OCIO approximation - I'll use…
From what I can tell, this maps scene linear
0 0 0to0.0196 0.0196 0.0196. Which makes pure black unattainable, because you can't go lower for the scene linear color? Is that really…
@brecht Thank you, and the answer to your naming question is actually related to @JoelR_VC's question about the blacks. Khronos did hold a vote and officially name this the Khronos PBR Neutral…
Perfect, thanks @Sergey. That will definitely be follow-on work; not sure how long it'll take and I think we should be sure everyone's happy with this first PR before getting started.
By the way, if there's anyone here who would like to nerd out about HDR displays and wide color gamuts, please let me know. I have an M1 Macbook Pro and I was playing with Blender's HDR support,…
By the way, thank you Blender devs! I had nearly given up on generating an OpenColorIO config for this tone mapper, as their documentation is so utterly useless, when it occurred to me that…
Done! Please let me know if there's anywhere I should put or reference my LUT generation script. Likewise please point me to any documentation you'd like to see updated (does that happen in the…
