Visualization (Chapter 1-4): Value Graph
3D Graph to analyze the value of texture maps Introduced in Chapter 1.4
Let me give you a quick breakdown of how the file works:
If you go into solid view, you can see that the scene consists of a whole bunch of intersecting planes.
Those have a shader that samples the texture's value from the XY-coordinates and mixes between transparency and emission by comparing the Z-coordinate to the value of the texture.
So a single one of these planes shows a simple line of the profile at the plane's position.
All together they create the whole graph by using a grid of planes.

love this one
Just a note as I start into this, all of the example files come up with Risky Connection and Virus warnings from McAfee. Might be something to look into.
@Gary Brimer have the same problem
This is moving a bit fast for me. I tried to reconstruct your first example with noise texture but nothing showed up on my plane. It remained white. I did notice that you have a ghost-like set of nodes behind the foreground nodes. I don't know what they do or how to produce them. Maybe I need to start a more basic course. This is cool stuff but for me it is going too fast without filling in the spaces. I might come back to this later after I go through more basic tutorials.
@steve kacenjar there are some lectures where you have to use prepared blend files and those files are not easily reproducable (as a programmer I think it is custom blend files)
is there a way to save this tab as a default I can pull up whenever i need? I love these visualizations but have no idea how to setup the perspective in other projects Excellent work btw Simon just going through these again
@fpowerm You can technically add it as a new workspace and scene to your startup file, then every file you create will have it as an option to switch to.
I think this tools should be a standard debug tools in Blender! Not being able to visualize the output of a node is like programming without error codes or others utilities.
Super smart! This is very useful to visualize how textures that say 3D and 4D work in a more intuitive way
Super thanks to you Simon! Visuals that let you see "behind the scenes", so to speak, definitely helps me understand an otherwise complex system.
Mate...this is the real in depth Blender learning, great stuff, many thanks.
i used this file for better understanding the workflow example 1. very helpful!
*@Huân Lê-Vương* Perfect, that's what I made it for as well! I'm glad it helps :)
Hey Simon- Could you please show us how you made this .blend file? I think it'll help me better understand this course. Thanks! :)
*@papertripping* Hey, to be honest, I don't think it adds a lot if I would make a separate video about this. But I added a quick breakdown to the description :)
*@papertripping* the node trees look intimidating :V it was easier in C4D for me with the clone system but i will have to adapt to the shading in blender.
*@Huân Lê-Vương* I made this file a while back when the nodes were much more limited and I had to use a ton more.
Now the noding system is more convenient to use
