Hi there. At the moment I’m doing a lot of research. I’m trying to get a better theoretical understanding of whats happening “behind the scenes” of three.js. These are topics like how does PBR work with its equations and so on. I’ve seen the article that three.js mentions when explaining PBR, but …

MSAA (multisample anti-aliasing)

Are you asking for the reference material used to create the three.js PBR materials?

Yes, kind of. To be more precise -> how does the look of the metalness in the metalness-attribut gets generated. Is there a general equation or something similar? I just want a deeper understanding of the origin of this concept.

[image] Kelle: is this link a step into the right direction? Yes. I suggest you also read the resources from the “Further reading” section. There are many papers, books and blog post about PBR so it shouldn’t be too complicated to find appropriate reading material. [image] Kelle: how doe…

Okay, I’ll give it a try! Thank you!

I think the three.js MeshStandardMaterial was originally based, at least partially, on this paper. course_notes_moving_frostbite_to_pbr_v32.pdf 52.11 MB I could be wrong about that, but in any case this PDF is a good overview of the theory.

In addition to this I have another question: Is the bump-mapping used in three.js a classic height field bump-mapping? I had trouble while researching this.

The technique is based on this paper: mm_sfgrad_bump.pdf 13.66 MB

Naty Hoffman’s introduction to “Physically Based Shading” course on SIGGRAPH university offers a really good overview of the basic theory in PBR. [SIGGRAPH University - Introduction to "Physically Based Shading in Theory and...] I suggest taking a look at it, if you haven’t done it al…
