Geometry Utilities

GeometryUtils.h provides a list of functions for performing 3D geometry computation, such as plane-to-plane or line-to-plane intersection. Here are the available functions:

Vectors

• Angle between two vectors
• Check if two vectors are in the same direction (angle < 90 degree)

Point

• Projection point on plane
• Nearest point on line

Line Segment

• Extend line segment by length
• Form longest line segment from a list of co-line points
• Check if a point is in between a line segment

Intersections

• Line & plane -> point
• Line Segment & plane -> point
• Line & line -> point
• Line * line segment -> point
• Plane & plane -> line
