Hi, I am trying to achieve a smooth color gradient along a curve between two points. The panel that I connected to the gradient slider shows that I did indeed achieve a gradient between white and black, but the custom preview is only showing the last parameter, which is black. I used the list item …

Rhino.Display.DisplayPipeline.DrawGradientLines is available in Rhino 7 DisplayPipeline.DrawGradientLines Method summaryM:Rhino.Display.DisplayPipeline.DrawGradientLines(System.Collections.Generic.IEnumerable{Rhino.Geometry.Line},System.Single,System.Collections.Generic.IEnumerable{Rhin…

Wow, I need to learn C#. So easy now. Thank You!!! :slight_smile:

Be warned, that trick currently only works with lines. We don’t have an implementation that works with curves at this point in time.

Ah, ok. I also just tried baking the gradient in that line using the Human plugin and it didn’t show up… I think probably doing what I want with it might be easiest in Illustrator then. Thanks again!

really nice @stevebaer ! please the parameter stroke width could be as an input. All fine on Windows but on MAC it doesn’t show width and this happens in GHGL as well, please consider to be fixed.

Would it be possible to insert different colors at different parameters of the curves? What do you think?

Absolutely that is possible. Here’s another sample hello_shader.gh (25.8 KB) [image]

That one is great but I think I could not explain myself clearly. I would like to do something like the picture below. [Screenshot_3] I want to show these 1 and 2 parameters red and the gradient according to these. I have these dots for all the colors but I don’t know how to arrange the graident…

Hi @stevebaer How to use list of colors to make gradient from list of lines in this case? I have 0 knowledge in c# and python code will be helpful. [image] Line Color Gradient___.gh (11.3 KB)
