Wedge vertices?

Help and Feedback Scripting Support
#1

I’m working on a Plugin and looking to implement a feature that’ll re-insert Nodes after a user removes them and finishes a session.

Currently my setup uses x2 Wedges to create a ‘Plane’ between 3 Nodes as depicted below.
How would I be able to find these exact three points of the Model once the Nodes have been removed and there’s no evidence of their previous whereabouts?

Any help will be greatly appreciated!

EDIT:

I’ve found a method of doing so, however when I apply it to pre-existing terrain it generates multiple versions of the same Node - Does anyone have any theory on how I can prevent this?

Hi there again lol . You can try getting the 4 corners of the wedge . there your half way there! Now you got to figure out whoch node you want to remove by comparing the direction it is facing

I would recommend to solve the simpler version of the problem first. Since you’re generating the 2x wedges, you would always know the orientation of the wedge (ie, where the 90 degree corner is in the object space versus the 2 45 degree corners). I would recommend to figure out where the 45 degree corners are located first for each wedge, then combine the two wedges and merge one of the nodes.
