This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Determining the 3D coordinates on a polygon's surface

Hello everyone,

I'm after a way to find the 3D coordinates of random points on a cube polygon.

I've created a cube polygon and dragged it somewhere in the scene. Now I obviously have its centre's coordinates, and mathmetically, should be able to determine the coordinate of any point of its surface but that would be troublesome.

Is there a way that I can find the coordinates of any arbitary point on the surface by clicking on it?

Any help would be appreciated - M

I was thinking maybe i can create another small polygon (1x1x1) and attach it somehow (automatically) to one of the surface of the main cube polygon - does that make any sense by any chance! user added image
