Enabling** Preserve Original Coordinates** will skip centering of the cloud. Be careful though, if the cloud uses very large values for XYZ data, it is likely to introduce precision loss, as internally, the data is stored as 32-bit (there are a number of reasons for it). However, this usually manifests itself as point “banding” rather than just an offset.
With regards to the performance
VR is inherently more performance-hungry, so I’m not surprised it drags the framerate down. Unfortunately, I haven’t used Faro, so cannot speculate on their optimizations.
If possible, I would advise to:
- Disable shadow casting on Point Clouds
- Opt to use Eye-Dome Lighting instead of Ambient Occlusion: LiDAR Point Cloud: Eye-Dome Lighting
- Tweak the Point Budget and Min Screen Size properties, while also compensating with Sprite Size Multiplier to try to achieve better overall performance without noticeable loss in appearance
The option to concentrate selected point budget towards the screen center is already on the todo list and should provide better results. In addition, I’m exploring some other techniques to use the available rendering resources more efficiently
