*@Devanshu Tak* I had the same thought, particularly about ray-marching. So if that question mark after Addendum means something like "depends on demand" then here's my vote for it. :)

*@Devanshu Tak* Yeah, I also vote for Vector Displacement and also for achieving realism.

Mathematical Background at least in part, would be helpful. Given so much of this revolves around vectors, it starts to feel like a bag of tricks if you don't see how all the linear algebra fits in to why combinations of vectors do this or that in a visual way.

I find vector displacement the least interesting out of the addendum, due to the fact that I jave ZERO idea where they would use it in production. If anyone knows use cases where it was favourable to use it please educate me. So Math, Proc Real, and Ray Marching get my vote.

15th July 2020 - 17:09

*@Adam Yoohasz* There's Vector Displacement Brushes in ZBrush. Not that this is directly applicable in Blender, but I could see it's use for convex -> concave decal work where normal+displacement doesn't quite work. However, I mostly agree, largely a niche case that's "neat" if not used specifically as a tool.

Perhaps related to ray marching, I’d love to see a discussion of things like parallax mapping for decals or parallax occlusion mapping for windows.

With procedural shaders you get infinitely resolution, so you can zoom really deep in without getting blocky/blurry results. But you get ugly results if you have to zoom out or be far in the background. Do you talk about solutions for this problem too?

Simon Thommes

6th August 2020 - 10:24

*@Andreas Friedel* I am not exactly sure I understand what you mean with 'ugly results when zooming out'.
Due to the fact that you are not bound to tiling for large areas as with photo textures, if anything I would argue the contrary.

But this course contains the fundamental techniques that you can use to accomplish practically anything. Generally the trick is not relying on singular base textures but mixing multiple noises if you want more natural variation. This is something I talk about as well, but the main focus is on the techniques and concepts.

i would like to know more achieving procedural realism, because i started working with architectonic visualization.
thank you

Can you to make a tutorial about Worley's algorithm "Cellular Texture Basis Function"

*@Huân Lê-Vương* I won't add something specific like this to the course, sorry. But with the concepts from the course and some additional thought, you might be able to pull it off yourself.

As a tip how to set up worley noise: You can define a regular grid of cells on the coordinates and then evaluate the random values of the cell neighbours. And the random values you can use to place dots. The worley noise is then the distance to the closest dot.

But, of course, you can just use the voronoi noise texture node. Setting it up yourself is a nice exercise. But if you just want the result, the voronoi noise is the way to go.

*@Huân Lê-Vương* Soon, a couple of things have thrown me off schedule, as I am mostly working on other projects at the moment, but I am just finishing it off now.

@hasysler* ray-marching is a technique that can be used to fake depth and do some other cool things. I used it on the settlers project for example: https://cloud.blender.org/p/settlers/5e863d958f0b5df3d84def37## Oliver Iliffe
