I am trying to rebuild a polysurface to make it one single untrimmed surface as I am now exploring texture mapping on rhino (UV mapping).
I tried rebuilding the polysurface with patch/ network surface to no avail. The surface is either too far from the original shape of not suitable for mapping.
I might have not had the parameters right but I have been trying for weeks and I can’t get it to work.
Hmm, if it has taken you several weeks, something is off.
If it has taken you several weeks, something is likely not quite right.
In my experience, I use Rhino as the central “control tower” and rely on other specialized applications for certain tasks, as Rhino has its own limitations.
If you try to unfold to flat surface one untrimmed surface with that shape in Rhino It is similar to asking a Ferrari to drive through a river.
That said, I may not fully understand your final goal or the specific problem you are facing. It might well be possible in Rhino. Is this only for rendering? If so, I recommend first learning the different UV mapping projection methods and the UV mapping tools in Rhino. You will quickly discover that untrimmed surfaces are not a limitation for UV mapping.
Is your main goal UV mapping?
And if you want an even more realistic display of UVs, you can use RizomUV.
If your intention is the one mentioned in the title, it is difficult to achieve that shape using a single untrimmed surface. You will need to model it manually by moving control points and adding several CVs and adjusting the degree.
Yes it is taking me weeks, obviously not 24h/7 but it has been really frustrating.
I am trying to flow a mesh texture on the surface, and it can only do it in one single untrimmed surface if I am not wrong. I tried to use grasshopper too but I am not really succeeding with this either:
No unfortunately the one single untrimmed surface is all wonky, I just did it as a test. I am using the flow along surface command to flow a mesh that I trimmed to the unrolled surface/ UV mapping
In the displacement settings, replace my texture to yours. Adjust the height using the white point. Using initial quality low resolution, experiment with negative and positive values using. Then, when you’re finished, slowly increase the initial quality resolution until your PC stalls. Save frequently.
Yes that could be an option to map the texture “displacement map” on the polysurface however, The texture definition is lost with that method and it needs to be extra sharp like the mesh for the CNC… I am trying to think that what I am trying to do is impossible haha
Thank you for your reply. I tried a rail revolve but then the mesh I need to try to flow along a surface gets completely twisted as the mesh spirals around the surface…
