Can I bypass Rhino 6 limitation of 849 points grid dimension when using the Grasshopper? What should be the input source - a file (list of coordinates - ASCI grid? xyz list?) or a point cloud as a Rhino 6 object? The last option seems to not work.
Hi Amsarse,
do you find this topic helpful?
I used this previously and it seemed to work for me. Still it is hard to judge by the info from you.
Cheers.
No, it is about a method of coloring a point cloud to create a map. My question refers to such situation:
I have my 1201x1201 point grid on which a mesh could be very easily stretched but instead, Rhino applies its own algoritm maybe statistically good for a random point cloud. It interpolates between my points instead of using them as vertices (it has a u/v limitation 849 points or something. What I need is rather 2.5 D processing instead of 3 D.
can you post data so we can take a look whats inside?
I uploaded the file. It is a simple case - just square point grid. I’m interested in such a solution which triangulates not square, random point grid (Delaunay triangulation?). In this case, the normals of the resulting trianles are almost parallel (relatively small differences between z coordinates). And I want the original points be preserved as the resulting mesh vertices.
Sorry where? None of your posts in this thread have a file linked/attached.
Thanks!
Either way, is this what you are after?
I “jittered” a grid of 1201x1201 points along the Z axis and then created a Delauny Mesh from the points.
The result of this method is that the vertices of the mesh are in fact the vertices of the point “cloud” grid.

Keep in mind this is not a FAST method at this amount of points (1442401 pts):
If you would share your end use case I think there’s probably better/faster solutions to what you are after.
I uploaded the file the way another user recommended as the file was above 20 MB and he was able to open it. Thanks.

I see, that make sense
