Whether you work with massive point clouds regularly or just occasionally, here are tips on how to handle them efficiently.
NUBIGON is the most powerful reality capture engine. Even though it can render unlimited volumes of point cloud data in real-time, you have to be mindful of a couple of things. When opening a point cloud for the first time, NUBIGON converts your data into a high-performance file type called octree. This conversion happens only once and gives you a unique ability to handle massive point clouds with ease.
Here are some important tips to help you make the most of NUBIGON:
Keep Your Project on an SSD
SSDs are much faster than mechanical hard disks and they will definitely reduce the time to open point clouds.
Prioritize E57 File Format
Point clouds in E57 format take up less disc space than text files like PTS and XYZ.
The first stage of octree generation is completed significantly faster for E57 files compared to text file formats.
Keep Your Source Files Elsewhere
For opening point clouds, your source files (E57, LAS, etc.) do not have to be in your primary drive. Keep your point cloud files in a different drive to save space.
Move Your Temp Folder
When opening point clouds for the first time, NUBIGON creates temporary files that can get as big as your source files. Choosing a folder on a secondary drive for your temporary files will save space. If your computer does not have a secondary drive, you can also use an external disk.
Clean the Data A Little
Point clouds may have extreme outliers. When generating octrees, those outliers can significantly prolong processing time or cause stability issues. Before opening point clouds in NUBIGON, apply bounding box clipping in your registration software.
Be mindful of running multiple software programs
NUBIGON reserves part of your available RAM when generating octrees. Running multiple programs at the same time reduces available RAM and thus prolongs octree generation.
