Creating a false color plot from topological surface

Rhino Rhino for Windows
1

Hi Everyone,

I’m a very new user to Rhino. I’m attempting to make a false color plot from a topological surface. The objects are two yeast cells with topographical information derived from light interference.

I’ve been searching through the forums and help documentation for a few days now with no luck. I came across the GradientView command but could’t really get it to work.

If anybody could help it would be greatly appreciated.

Best,

Hi Luke - Do you mean height info, by color?

Hi Pascal,

Thanks for the help, this is exactly what I’m looking for. What tools did you use to make this work?

Hi Luke - try this:

Select your objects and with the Front or Right view active, look in Propertries > Mapping page. There, set PlanarMapping>BoundingBox >CPlane> Mapping channel 1.

Then apply a texture of some kind to the object material - I used a two-color gradient texture, but you may have an image that has the correct colors for your height range.

The mapping plane can be adjusted so that the gradient falls at the correct elevations,

Set the viewport to rendered mode, or use SetObjectDisplayMode

Hello Luke,
Very nice work!
I have a matter about the above picture.
How do you add the color slip(Height) on the right of the picture?
