Massive Scan Issues
Hi,
I am dealing with an utterly massive scan. 204 lidar stations and 46,000 40mp photos aligned. A small section meshed at 6.6 billion tris and when finished. all of the parts should be in excess of 50+ billion and this is meshed at NORMAL setting with a vert separation of 0.5mm so there is much more detail than I can pull. I have had hit and miss success using colorize as opposed to texturing. I'm looking to export an LAS primarily for now, are there any settings in colorize which might prevent a week of processing only to get garbage back? I've never had success using draft colorize.
Thanks,
Jeff

This is what I would use(downscale 2 means twice less resolution), but honestly with such heavy detail as you have in terms of polygon count, this could still take ages. The only effective way to produce something for you here would be to use simplify on the parts to lower the poly count as this is an insane number for process like coloring is. Coloring paints colors on every vertex and you have lots and lots of them so reducing the poly count speeds up the whole process. Unfortunately in an extreme case as this is, even simplify will need some bit of a time to take it down. It still will be the fastest way. Next time, while working with so many inputs, you should consider using downscale in reconstruction and bigger spacing between vertices, but I suppose you already know. -
Thanks Erik,
If it takes a while, that's ok. I am just trying to see if there are any settings I was missing but it is pretty straightforward. Best thing I can do is cut the mesh into smaller chunks. I never thought I'd say cutting into 1-2billion tri chunks makes things more manageable but it does. It's an impressive scan and we will hopefully be showing it soon.
