Wrangle Node Example - Torus

Posted Jan 23 2018 Updated Jan 21 2023 Updated April 20 2026

An example of using a second input on a pointwrangle node

is explained below.
This example is based on an expressions tutorial to blow a torus up from a since removed tutorial on expressions from SideFX back in H9. I have created and updated this example using point wrangles as seen in my file

. I also added blending from another demo and implemented this with a sequence blend, point vop and finally updated to use point wrangles.

The points are

"uniqued" on each facet
facets scaled to zero
sorted by primitive number
noised the position thru a particle node
pointwrangle mixes using the lerp function to blend them back together

The syntax I used here was v@P2 = point(@OpInput2,"P",@ptnum);
