Unity3MXB

Load 3MX/3MXB LOD model files generated by Bentley ContextCapture into Unity.

NOTE: When using Bentley ContextCapture to generate 3MX format LOD model files, there is always a 3MXB root file generated under the Data folder. We use this 3MXB root file to import the model into Unity.

Tested Env:

• Windows 10
• Unity2018.4.23f1

Thirdparty (source codes included for convenience):

• OpenCTM
• NanoJpeg
• Newtonsoft.Json-for-Unity

Known issues

• Frame rate is NOT stable because mesh and texture could NOT be uploaded to GPU in thread(I do not know whether this is a Unity issue or just because I am not an expert of Unity).
• Cache strategy is NOT optimized.
