Point Cloud Library - Wikipedia
https://en.wikipedia.org/wiki/Point_Cloud_Library
The Point Cloud Library is an open-source library of algorithms for point cloud processing tasks and 3D geometry processing, such as occur in three-dimensional computer vision. The library contains algorithms for filtering, feature estimation, surface reconstruction, 3D registration, model fitting, object recognition, and segmentation. Each module is implemented as a smaller library …
Point Cloud Library | The Point Cloud Library (PCL) is a …
The Point Cloud Library (PCL) is a standalone, large scale, open project for 2D/3D image and point cloud processing. PCL is released under the terms of the BSD license, and thus free for commercial and research use. Whether you’ve just discovered PCL or you’re a long time veteran, this page contains links to a set of resources that will help consolidate your knowledge on PCL …
PCL Walkthrough — Point Cloud Library 0.0 documentation
https://pcl.readthedocs.io/projects/tutorials/en/latest/walkthrough.html
The keypoints library contains implementations of two point cloud keypoint detection algorithms. Keypoints (also referred to as interest points) are points in an image or point cloud that are stable, distinctive, and can be identified using a well-defined detection criterion. Typically, the number of interest points in a point cloud will be much smaller than the total number of points in the …
Ray Tracing Methods for Point Cloud Rendering
https://webpages.tuni.fi/vga/theses/Ray_Tracing_Methods_for_Point_Cloud_Rendering.html
Direct point cloud ray tracing methods consider local features of the point cloud to generate intersectable surfaces only when needed. In this thesis, we survey and compare different methods for directly ray tracing point cloud models without global surface reconstruction.

point cloud has certain known properties and the sur- Since ray tracing is based on casting rays, whose di- face properties are fixed. Hence, when changing mate- rections depend on the surface normals, we need to de- rial properties etc., the rather expensive preprocessing fine smoothly varying normals over the entire surface, steps have to be recomputed.
Tracking object in real time — Point Cloud Library 0.0 …
https://pcl.readthedocs.io/projects/tutorials/en/latest/tracking.html
After you created model point cloud and the executable, you can then launch tracking_sample. Set device_id as second argument and pcd file’s name you made in above 4 as third. $ ./tracking_sample “#1” tracking_target.pcd. After few seconds, tracking will start working and you can move tracking object around.
Splat-based Ray Tracing of Point Clouds - zcu.cz
https://dspace5.zcu.cz/bitstream/11025/1426/1/Linsen.pdf
We present a ray-tracing approach for objects whose surfaces are represented by point clouds. Our approach is based on casting rays and intersecting them with splats. Since ray-tracing methods require smoothly changing surface normals for producing the desired photorealistic results, splat generation must include the derivation of such normals.

https://forum.planetchili.net/viewtopic.php?t=3291
The method I call point-cloud ray-tracing is very similar to hybrid ray-tracing but there are some important differences. As you may know a "point cloud" is essentially a collection of points, each having a xyz position in space and also a color. Objects in the scene consist of many of these points, you can almost think of them like atoms.
