Populate points according to colored mesh

[sreehari793]

I have a radiation analysis mesh and would like to populate points onform01.gh (179.5 KB)
the mesh according to the color of the obtained colored mesh. (i don’t know if I’m right)almost similar that wen populate a surface with image sampler. is it possible ?

Hello
you already asked a similar question.

Point density from a coloured mesh

As a color is 3 values you must define a distance. For example brightness … Here a simple way to populate depending on height [image] You could also use that

I think you like complexity so you don’t manage to make what you want. I am not used with solar radiation but I think the output is not a Color but a value in an interval. The gradient representation is just a way to represent the radiation, temperature or whatever. So why not outputting a single value represented by a grey value !!! The grey is far simplier to use.

Point density from a coloured mesh

Here is a solution, as I have not searched for the equation on the gradient, here is a way that will work if you stay in Grasshopper Gradient.It uses the fact that Color is transformed to point in Grasshopper, points that are in a cube from {-1,-1,-1} to {1,1,1} I put a Graph Mapper in order for you to tune the density of points.
