Best file format to export heavy mesh?
« on: April 08, 2018, 05:45:28 PM »
What's a file format take less time to export in Photoscan.    I tried fbx to export 200 mil mesh and it never complete actually.  I think fbx is  a quickest one in Reality Capture for example. 

Obj is pretty slow too . Not surprising considering how ancient  the obj is. 
So which one is the best in Photoscan?

ps. I tried decimation and it takes forever in Photoscan.  Wonder if it worth using it time wise?

Hello kirk,

Decimation of 200 millions mesh could require 25-30 GB RAM.

As for the export formats, you can try Alembic export. But what's the purpose of using 200 million mesh?

Thanks Alexey,   200 mil mesh is for baking  height map/normal map of a subject  in a 3d party texture baker.  In a word for modern  kind of a surface material.

I ones did 800mil mesh with Photoscan. A patch of a ground surface.  So your question seems a bit odd for me.

Am I missing something? An easy way to export height texture at once,  altogether  with color/diffuse texture without wasting time for building and exporting  hi res mesh?

A texture where pixel values would be grayscale  deviations of dense point cloud dots from a low poly mesh shell?
