- Can we go over putting repeats of an image on the same side of a geometry?
We'll spend a lot of time on that today.
- what is the answer to the question When might you use colored material
and grayscale textures?
How could we put "dirt" on the pink ball? We could have a
pink color and use a texture that adds some grayscale smudges onto the
ball.
- I am still a bit confused about texture parameters.
The texture parameter indexes into the texture to pull
out the pixel (or pixels) that are applied to the surface.
- Can you re-explain cross-product :') / explanation of cross product
when it concerns direction? I didn't quite get the mental picture of how
to figure out the direction.
I'll demo.
