Merging cesium tiled models

Hello,

 

We've been doing 3d modelling with agisoft metashape, mainly small buildings. Right now we have a project of modeling 300 hectares of city and the outcome has to be cesium tiles and it has to be one unity. The problem is that agisoft cannot produce that large of an object in one go so we have to split into parts. How can i merge those parts back to one with FME?

 

Kind Regards

Hi @siim,

A couple of things come to mind, but it depends on if your model is spatially aware already. It looks like Agisoft supports exporting as KMZ so you could start there as FME should read in all of the parts in the correct location. Alternatively, it looks like we have some support for companion files on other formats like FBX that allow you to move features to a World Coordinate System if you want to give that a shot.

Otherwise, if your model is not spatially aware, you could simply read in the model and use a series of Offsetter transformer to move all the pieces in the correct location before aggregating to a single feature and writing to Cesium.

Hope that helps you get started.

Our chunks are georeferenced, what transformer to use for merging?

Hi @slim: If you haven't already done so, try using the Aggregator transformer.
