PLY Frequently Asked Questions
Everything you need to know about opening, inspecting, and converting PLY files in your browser.
Does this viewer support both point clouds and solid meshes in PLY format?
Yes. If the PLY file contains face elements, it is rendered as an illuminated 3D mesh. If the PLY contains only vertex elements without faces (a raw point cloud), Universal 3D Viewer renders it as a colored 3D point cloud.
Can I view LiDAR laser scan data captured with drones or handheld scanners?
Yes. Universal 3D Viewer handles high-density vertex data with per-vertex RGB colors, allowing you to inspect drone scans, photogrammetry models, and terrestrial LiDAR surveys easily.
