Merge Part Occurrences by Regions

Use this feature to merge part occurrences together based on their physical proximity in the scene, meaning by region.

Last updated 9 months ago
API functions:
  • scene.mergePartOccurrencesByRegions
  • scene.getClusters

Note
Use scene.getClusters to get part occurrences based on their physical proximity in the scene without merging them.
This function fits particularly with large AEC models, coming from Revit, AutoCAD, Navisworks or RVM files.

Indeed, if the model can be merged this function will greatly help with performances:
  • merging lowers the number of draw calls
  • by regions lets still benefit from frustrum culling (contrary to other 
    Merge
    functions that do not merge by location/region but by hierarchy)
This is particularly interesting with large AEC buildings where the model is the environment. If the user is at the center of the building and looking one way, the parts behind him won't be drawn. It would have been drawn if the whole model was merged:
