Custom Texture mapping from grasshopper on Rhino objects

Grasshopper
1

I want to be able to parametrically manipulate a design object, changing its shape, size, etc., and at the same time visualize it either in Enscape or real time Vray, but the tricky part is I also need a specific texture map to the right size, for example using a wood texture at 5’ x 5’ x 5’ box mapping.

As far as I can find there is no Grasshopper component that can do this correct? Vray grasshopper components does not seem to have any texture function. There is one component in Human, but it only map a texture to a mesh, and I don’t know if the texture map can work in Enscape? What if I want to retain the NURBs surface?

I’ve tried searched up and down and couldn’t find anything in Rhinocommon or Rhinoscriptsyntax to do this, there is this C++ code sample that I find:

This guide discusses materials, textures, and texture mapping using C/C++.

But how do we try to run something like that from Grasshopper as C++ would need to be compiled? Is similar function exposed in any other language?

Thanks!

Does this works for you?

interesting!, although it’s not immediately clear which method or property can help me modify texture map size, location, orientation, etc…let me see

TextureMappingType enum (rhino3d.com)

The first one is likely related to the texture, this one is more applicable to you, I’m currently busy but I may give it a shot sometime around the new year’s.

Thank you

Thank you tay!
I will explore it a bit too

I’m very curious about your outcome. Since this can fill the Gap of that missing functionality
