RAYGUN Fast Generic Geometry Raycasting Tool

When performing spacecraft simulations, developers sometimes need to feed the simulation with a distance between two objects along a certain direction vector. For example, if a spacecraft is approaching an asteroid and needs to simulate a laser rangefinder, the simulation would need to detect what...

iOrca Code Release

The iOrca outlier detection algorithm is based on the K-nearest neighbors approach. It calculates the distances across the dataset to determine if data points are near or far away from their set of neighbors. If a point has an unusually large distance to its neighbors, it is considered an outlier and of interest to the user....
