How to Divide, Mesh, Texture, and Export Large Dataset Using CLI

[Mr_Joshua_R]

Hello all,

I’ve been looking at the Divider3D and Large Dataset Pipeline information and tutorials and I am unclear as to how to get this working for what I need.

Currently I have an alignment of a large dataset (14k Images + laser scans) with a reconstruction region.

What I want to do is divide the reconstruction region into smaller areas, have each of these calculated with normal quality mesh, textured, and exported in FBX format ready for import into Unreal Engine.

If anyone can provide a simple explanation of how to do this I will be eternally grateful.

Thank you.

Hi MrJR,
everything is explained in these tutorials and there is no other information regarding it: Processing of the Habitat 67 Scan Data with the 3D Divider Script | Tutorial
Basically, as you have reconstruction region, you need to create more smaller one and then process each of those smaller regions to a models. But each step is explained in that tutorial.

Thank you for the reply, as mentioned I have been through this.

Dividing the regionn up is simple enough, however the latter parts are where I need help

the link for ‘all cli commands’ is broken on that page and so its hard to get much further

I did find this link to ‘all commands’ but I’m not sure how to be able to run the ones I think I would need using the information CR by RC has provided

Hi,
the link was corrected (but basically it is the same).
Regarding to using the divider script this is an useful video: Divider Script | Tutorial

Basically, after your reconstruction regions are created you need to use script for your project:

%RealityCaptureExe% -delegateTo * -selectComponent "Component 0"
%RealityCaptureExe% -delegateTo * -setReconstructionRegion "%RootFolder%reconRegions\box_%rowNum%_%columnNum%_%zNum%.rcbox"
%RealityCaptureExe% -delegateTo * -calculateNormalModel -calculateTexture -exportSelectedModel %RootFolder%Models\Model_%rowNum%_%columnNum%_%zNum%.fbx %RootFolder%\exportFBX.xml

For using this script you need to have created reconstruction regions and XML file for FBX export. Also, as it is mentioned in the tutorial, UseSavedReconstructionRegions Script is good to use, which will use previously created data and you should do slight changes as example above.

Ok, thank you for this.

I will see if this works for me
