"Yes! I've fixed it! Finally... Also thanks to some of your suggestions. Eventually I found a way to display the individually coloured breps without the red overlay. Sorry for the confusion, I am indeed working on a group of custom…"

Florian Frank replied to Joost Lauppe's discussion Setting the preview colours (C#)

"Yes...runCount is important if your Script gets executed several times within one change of data (supplied Brep list). Hm so your specified colors are all close to red? Did you use a DisplayMaterial with opacity or without? If the opacity is really…"

"Thanks Florian, I've used this runCount == 0 statement to clear the rgb and brep lists, is that what you're hinting at? I've come a bit closer to the problem, but still haven't resolved it. It seems that the breps are coloured…"

"Thanks Florian,I would expect the code to work as well but somehow all the breps turn dark red. I've checked the m_RGBNrs and they hold different numbers for the different breps.The thing which I can't explain is that the…"

"Hi Joost, the code seems to be right. I've done the same a lot of times...check your values in the m_RGBNrs Array/List! Here you can see an example: private void RunScript(List<Brep> x, ref object A) { breps = x; color =…"

Weaverbird - Topological Mesh Editor

Weaverbird is a topological modeler that contains many of the known subdivision and transformation operators, readily usable by designers. Instead of doing the work repeatedly, or sometimes using complicated scripts, this plug-in helps reconstructing shapes as meshes, subdivides and refines even polyline lists, and helps preparing the model for fabrication. Weaverbird is the first released addon for Grasshopper but the group is new, so please join it to participate in discussions, ask questions…See More

Setting the preview colours (C#)

Hi there,I'm struggling with this problem for a while now, so I thought i'd see whether someone could help me. What I'm trying to do is set the preview colours of a list of breps through the following method: public override void DrawViewportMeshes(IGH_PreviewArgs args){ for (int i = 0; i < this.m_ViewPortBreps.Count; i++){Rhino.Display.DisplayMaterial mat = new Rhino.Display.DisplayMaterial(Color.FromArgb(255 - this.m_RGBNrs[i], this.m_RGBNrs[i], this.m_RGBNrs[i]),…See More
