It’s interesting to compare the visualization of texture coordinates to the actual image. I’m curious as to whether the colors used at different points are associated with anything. The texture map appears to be a regular bump map, as the geometries aren’t deformed from details like the bricks. With that in mind, I wonder if the colors correspond to how displaced a pixel is supposed to be. I can’t really notice an obvious difference between how, for example, red vs. green colored areas as textured. The patterning is also quite interesting—I wonder what causes this sort of “striping” to develop.

agree with the other comments; is this visualization of the textures overlaid onto the model, or some combination of the two that creates the striping? i can't help but think the long side planes should be continuous if not this.

How I'm understanding it -- with consideration to the previous example with the orc head -- each square (floor/wall), pillar face, arch face, and the floor molding is a different object just copied/pasted throughout the space to create the entire room (im also curious about how this relates to clipping through surrounding objects in video games). This is quite apparent with the floor and walls as each square is copied/pasted to complete it. In other words, what we are looking at is just a bunch of pieces of different chocolate candies (call back to the santa chocolate wrapping slide) and visual texture coords are just purely the tinfoil wrapping. The image textures, the actual santa img, in the following slide are then respectfully applied to each relevant objects mapping. Again, the walls and floors are using the same img texture in the same way so here in the visualization they have the same texture coordinate. Also take note of the direction from red to green, this also determines how the texture is mapped to the objects (+ look at the diagonals on the right/left side pillar faces, flipping between this slide and the previous one makes it apparent they are also reflections of each other bc the mapping itself is reflecting the applied image texture)

I noticed how the flooring tiles are repeated and concatenated perfectly, yet the pillars have different texture mappings. So I'm curious how do we determine what should be the repeating pattern for a certain texture?

tiny follow up questions, why red and green? is there a significance or just aesthetic? also, is the ombre just for the sake of human visual understanding of mapping an image texture to the object and could otherwise just be a singular representative color for each object respectfully?

@jerrymby, I think with the pillars and overall even, it may be simplest to think of the visual texture coordinates as transforming the image texture. As you pointed out, the pillars make this really clear because each pillar face has different texture coordinates. So the pillar itself is the "chocolate", but each of its faces has a different mapping. Then that mapping determines how the image texture is manipulated and therefore applied. I tried to edit my previous statement to fit this thought process more.

This also raises another question for me... are the walls/floors just all one big chocolate bar and each perceived square is just a texture coordinate or is it actually a bunch of different tile objects that are repeated and concatenated as jerry describes. And are both methods valid strategies? Which is better?

The visualization of this texture model reminds me of my experience with 3D modeling. Mapping a texture material to a specific shape of a model took a lot of time as it required full understanding of the geometry. I thought such an implementation technique would only be required for applications, not for theoretical concepts. It is interesting to see the connection between theories and applications here!

Very interesting to see how the visualization of texture coordinates still shows the relative shape of the structure.
