walberla::mesa_pd::data::HalfSpace Class Reference

Detailed Description

Half space shape class.

Attention
The HalfSpace does not obey any rotation. The rotation is given purely by the normal of the half space!

Member Data Documentation

◆ normal_

Vec3 walberla::mesa_pd::data::HalfSpace::normal_
private

Normal of the half space in reference to the global world frame.

The normal of the half space is always pointing from the occupied half space towards the open half space.
