Hi,

I'm running Radiance (which is a lighting simulation software) in Houdini. I have gotten the results (see Image 1). Under the Points view, there is the column “illuminance” which stores all my results. What I want to do is to use the average of all the illuminance divide by the minimum value.

I have tried to do it with attributepromote node to get average value (image 2) and the minimum value (image 3) separately. But I don't know how to move on and to create what node to do that division.


I hope someone can help me here, thank you!

To cookie/cut an L system, I attempted 2 ways: 1. use metaballs as a boundary zone to limit its growth but there are sometimes protruding lines from the L system; 2. Polywire the L system then cookie it with a volume but the cut section always have more than 3 points as polywire makes L system into a 3D polygon. Both methods do not do clean cuts.

Is there any other way to have a clean cut wherever I want in the L system?

I have 2 sets of points at different height, one at a higher elevation with the other at the lower elevation. I'm trying to extrapolate lines for each point at the lower level to the points at the higher level. How do I do it?
