Question about requirement for procedural_color.glsl #7

Closed IgorStempen closed 5 years ago

IgorStempen commented 5 years ago

Hi,

I know that the explanation for procedural_color.glsl says to be creative, but I wanted to know if there were any strict requirements that have to be met for this function?

I am having trouble making mine look exactly like the example. Would an implementation such as the one that I currently have be sufficient?

yes it will be hard to make yours look exactly same. Yours looks fine to me.

I'm kind of stuck on this part. Are we supposed to interpolate the point from a 2d grid, or a 3d cube?

My sphere kind of looks like this, and it's just brutal. I feel like I'm over doing it. I'm trying to interpolate the 3d point over a 3d cube using the random vectors as vertices.

There's sigmoidal shapes on the surface, so it's kind of working? (I disabled phong)....any ideas?

its 3d grid
