Grasshopper

algorithmic modeling for Rhino

 i want to render the mesh to have some color , the color is based on the angle between mesh normal and Z axis.

I want the color to be smooth gradient, because the normal angle changes smooth.

but the result seems wrong.

there are some suddenly color change on seams, 

why?

the gh file is in attach files

There are two issues here:

Firstly you want to re-colour the Mesh by vertex so you need to create a new mesh based on the old Vertices and Faces with the new colour applied.

Also the Bounds should address the whole solution not just each Mesh so you need to Flatten its input

Alternative solution:

thanyou . good idea!

thank you very much . i have tried flatten before, but seems did not flatten the right position. thank you
