I saw a couple of you deal with huge topography data sets. Can you give your recommendation on how to setup file and manage and work with such big volume of information. For example, I have a survey which is about 50Mb csv file. It is a huge area with lots of points.
Geo Location. Information imported from survey usually placed in world coordinates, miles away from Rhino origin. What is the best practice, would you move the model closer to Rhino origin with offset record?
What tools are you using to construct the mesh from points? Grasshopper?
If 2 is yes, how would you separate the data so Grasshopper is processing information bit by bit?
If topography is too detailed (which it good) and Rhino/Grasshopper straggling to work with , would you consider reducing LOD of the mesh ?
If 4 is Yes, how much would you reduce the resolution? Are there any good practices or guides?
use cloud compare to do an initial sub sampling to get higher/lower resolutions where needed. This would give you the ability to dial in the resolutions that will work well in Rhino fairly easy, using separate files (worksessions) to move in-between resolutions.
then either use the poisson in cloud compare to mesh or the latest and greatest Rhino plugin Cockroach.
