How to Morph an object from Flat Mesh to a 3D Mesh Using UV Coordinates

[Denis90]

Hi, I just a newbie in grasshopper, and I am stuck at the issue below.

What I have is a flat mesh (source) and a 3D Mesh (target), I have another mesh (object) on the flat mesh, please notice that the object is a thickness mesh with complex shape. Another notice is the source, and target is sharing the same uv coordinate.

So, what i want to do is to transfer the object from the source mesh to target mesh base on the uv coordinate. Please share the idea how to do it!

Appreciated with your sharing
Thanks,
Denis

Hello
there are some tools to Morph from one geometry to another one.
Mesh Map (but it is limited to object on mesh)
Mesh Map from Nautilus plugin, I added the distance from the mesh so it works with object with thickness
MeshCageMorph will need some cage (3d)

But I thing you’ll need to make some C# or Python to transform 3d coordinate to UV coordinate.
You’ll find some ideas there

From procedural texture to image texture (How To)

Here is a way to transform procedural texture to a texture file. In this description a procedural texture is a function that transform a coordinate in euclidean space (X, Y, Z) to a colors (Red, Green, Blue and why not Alpha). Unwrap the object(s) you want to texture, this object could be also an object that is just used as support of UV mapping (used with Texture Matching) [image] 1bis) You can edit the UV map in UV editor in order to optimize the placement of objects.

if you want more elements, you’ll certainly have to publish some data.

hi @laurent_delrieu,

What a plugin! it works perfectly. Thank so much for the help.

So at the end you didn’t need the UV coordinate just using the fact that meshes have the same topology. You must have used Mesh Map ?

Thats my misunderstanding, as I am just new in grasshopper, and i thought that was UV coordinate, but turn out I should say same topology. Appreciate for the new knowledge.

It could have been UV coordinates, but it is less frequently used. Lots of tools in Grasshopper, among Nautilus, don’t take into account UV coordinates so they are lost after transformation.
This is also a reason why most helpers on this forum insist to have realistic data (geometry script …) because devil is in the details. You can read this to have further explanations
