- 24. USE CASES
- 25. Storage Reduction • CAD/CAM – Visualize 100 Millions polygon assemblies on any type of devices – Batch process of 120 minutes to generate 7 LOD – Compress data in 2 minutes. – Reduce the file size by 40.
- 26. Reverse Engineering • Make Scan to generate CAD/CAM model to integrate in PLM process for maintenance – – – – LOD Generator can process 1M Triangle / minutes Visualize up to 60 M using 7 LOD Reduce the files size by 30 Reduce the loading time
- 27. Collaborative Engineering • Manufacturing Process Review – – – – Visualize and interact on the same model using local and remote device Use Compressed Format to stream the model over the network. Decompress on remote device using OpenCL User set the appropriate Level Of Detail on remote device manually or automatically – Reduce the Bandwidth – All remote user to show the model Remote – Possible integration on existing Framework Viewer Compressed Models Server Remote Viewer Remote Viewer
