Hi all simple question (i hope) how does one divide any given surface into a quad grid so that the points of the grid are always spaced in a certain distance from each other (lets say between 13 to 18 cm for example) meshing would be a good answer (if it works) - i tried the mesh options min/max edge but that didnt really work for some reason (my guess is the long diagonal edges ruined it but im not sure)
you can't. When a surface is doubly curved, it becomes impossible to constrain distances in both directions. It can be done with flat and singly-curved surfaces (provided the curvature direction matches one of the principal directions of the grid I think).
If your surfaces are flat, I suggest you use a Rectangular Grid component to create your points. If your surface is singly-curved it becomes more difficult. Can you post a picture/file if this is the case?
Hi David
Thanks for the reply, although its not what i wanted to hear
Yes - the surface is double curved, and no i dont have a file since i am looking for a general solution
do you think that a triangular grid divided arranged as hexagons will be able to solve this?
the quads are not as important as the distances for me
there must be a way
No, there's absolutely no way to put a grid with distance constraints on any given surface. This is only possible for a small subset of surfaces, and then often only with directional constraints for the grid lines.
This is why maps of the Earth can preserve angle or area, but never both.
i'm turning to the mathematicians for help with some kind of triangulation
I'll let you know what i discover, there might be an algorithm that can do this for some surfaces
