archz2 Posted September 9, 2022 Share Posted September 9, 2022 I was experimenting with voronoi fracture and copy to points. I did a Boolean operation on resultant cluster of boxes. Now it automatically clustered some sets of boxes on its own. Some consist of 3 boxes, some consist of 2 boxes, etc. Is this clustering random or it has some logic to it? Moreover, how can I control which boxes get clustered together? Like, choosing the top three, then bottom four, five on the left, etc. CLUSTERING QUESTION1.hip Quote Link to comment Share on other sites More sharing options...
Fenolis Posted September 12, 2022 Share Posted September 12, 2022 This looks like a bit of a bug with Boolean not handling coincident planes very well. 1 Quote Link to comment Share on other sites More sharing options...
archz2 Posted September 12, 2022 Author Share Posted September 12, 2022 Okay, so how to tackle this bug? Also, how can I control which boxes get clustered together? Quote Link to comment Share on other sites More sharing options...
Fenolis Posted September 26, 2022 Share Posted September 26, 2022 You can try to create cluster attribute on the points before copying boxes, then running a loop over each cluster, copying the boxes, Fuse to snap points, Boolean union. For creating cluster attribute, you can try "Connect Adjacent Pieces" set to points so that all points link to nearby ones (and not diagonally), then use "Find Shortest Path" to create a Tetrimino-like shape. Generally, Boolean works best with intersecting geometry. There is a new Polyscalpel node in 19.5 that is a bit more flexible with coincident geometry, which you can try.
