Hi all! For a big project I’m needing fast mesh slicing … but actually only for displaying purposes! So, by some tips I’ve received, I’m trying to do it with GHGL. Problem: [GHGL clipping plane attempt] The script: GHGL clipping plane V0.1.gh (22.1 KB) This is actually less than 5 …

You will want to perform your clipping side test in the fragment shader and use the discard glsl instruction to throw away pixels that are clipped

I’ve not been brave enough to dive into shaders yet. Good luck with that! I wonder why you’re not using clipping planes? There’s a bunch of c# nodes floating around for creating and orienting clipping planes. I use one of them regularly and it works pretty well.

[image] dharman: There’s a bunch of c# nodes floating around for creating and orienting clipping planes. Yes, I know, I made one of them in the past. But any clipping plane will clip all geometries on the rhino viewport, even normal GH previews… I need a per-object solution. A “selective” c…

Selective clipping per object is available in Rhino 8 if that is an option. There are still a number of bugs I’m working on for this, but I’m hoping to have them fixed in the next couple weeks.

That’s a good news! I can’t wait to use them… But my situation is with rhino 7, and my customer will use my script in many different machines with rhino 7… I’m trying to filter also from the Vertex tab but it results in a “sawtooth” cut of the mesh, obvjously… [2022-03-19 17_04_56-Window] [2022…

[2022-03-19 17_29_48-Window] GHGL clipping plane V0.2.gh (32.9 KB) That’s it! Thank you!! :star_struck:

Looks great. That style of clipping (boolean combinations of multiple planes) probably won’t be supported in Rhino 8 anyways so it’s good you were able to do it yourself.

@maje90 These days I’ve been working on Clipping Plane in GH and found this threat. Just a thought, can GHGL clipping has view assigned/specified individually? (Top/Right/Front/3D)

Stuff like this would be sooo handy…
Awesome rhino!
