Incidence Angle To Cd

[peliosis]

How to add point color based on angle between point normal and camera.

Further on, I'd like to operate on points based on their incidence angle.

In vop geometry operator context globals, there is N but there is no I

You can create your own I vector by grabing the camera position and subtracting your points positions.

Here's two ways you could do this; either with expressions or with vops.

Are you going to say this took you the 5 minutes between my posting and rereading:)?

Thanks a lot! There should be more help examples on expressions and vops.

Dziekuje bardzo;)
