Here a short tutorial on using the Ray Collision Xpresso node.
The node is used to get the polygon that was ‘hit’ by the Ray.
Python is then used to get the neighbor polygons.
All these polygons are added to the Polygon Selection Tag.
What you will learn:
– Use of the Ray Collision Xpresso node.
– Interface Xpresso to Python
– Get Neighbor polygons in Python
– Set selection tag in Python
