@miniapeur Research scientist (in the US). Nothing wrong with postdoc, but after you finish it, the right answer will still be research scientist (in the US).

@wenzeljakob I, for one, welcome our new colorful flame overlords

@wenzeljakob Bonus golden badge for submissions typed on typewriter and mailed in by Fedex. 😉

@vdeschaintre @jasonvestri 🤣

@Peter_shirley Though CPU works pretty reliably

[Milos Hasan @MilosHasan]

@Peter_shirley GPU rendering in Stager only works on Windows/Nvidia currently

@ejdeon This is correct; keeping color and sigma in NeRF separated has various benefits, allowing for separate architectures to learn them, or to discretize one and not the other, etc.

[Milos Hasan @MilosHasan]

@SebAaltonen I'd recommend creating a procedural material, and training a network that maps a photo to the parameters. Like https://t.co/WskN9ncPd8, ignore the slow differentiable / optimization part, just check the neural network initialization part. The result can be tileable and high-res.

[Milos Hasan @MilosHasan]

@ejdeon I hope to read your book soon btw.

[Milos Hasan @MilosHasan]

@ejdeon Btw. I believe the paper "Microfacet BRDF generator" [Ashikhmin et al 2000] has a Section 5 that described this coupled BRDF in more detail, so should be a more appropriate reference.

Join us tomorrow at 11am PT for
NeuMIP: Multi-Resolution Neural Materials presentation and Q&A.

You can try it for yourself! Real-time WebGL demo: https://t.co/9jew87c6QV

@twominutepapers made an amazing video covering the paper! https://t.co/vKqzRpZf3S

@Xelatihy Good points though I’m not aware of an alternative that would solve these and not introduce other issues…

[Milos Hasan @MilosHasan]

@Xelatihy Ah, yes, though I think full path tracing will be eating into the real-time world more over next few years.

[Milos Hasan @MilosHasan]

@iliyang @siggraph Or hated, by people with plans after the deadline

[Milos Hasan @MilosHasan]

@Xelatihy You can also use matrix power. Rotation matrix raised to a power less than 1 will give partial rotation around same axis.

[Milos Hasan @MilosHasan]

@Xelatihy Not teaching, but you can easily find the rotation axis of a rotation matrix R (it’s the eigenvector). Then you can rotate around same axis with smaller angle.

@TomDuff @Peter_shirley Yup, worth thinking which “impractical” ideas will be left standing in ~20 years.
