Detailed Description

A class representing the geometries associated with a collision.

This class contains information about the position, orientation, and size of the contact surface associated with a collision. It also includes additional fields for tracking the state of the contact and for use with specific contact models.

Examples: 0_demo_erosion_issue.cpp.
