Detailed Description

Definition of a half space.

In its canonical frame, the plane defining the boundary of the half space is that frame's z = 0 plane. By implication, the plane's normal points in the +z direction and the origin lies on the plane. Other shapes are considered to be penetrating the half space if there exists a point on the test shape that lies on the side of the plane opposite the normal.

◆ MakePose()

Isometry3< double > MakePose ( const Vector3< double > &  Cz_F,
const Vector3< double > &  p_FC 

Creates the pose of a canonical half space in frame F.

The half space's normal is aligned to the positive z-axis of its canonical frame C. Given the measure of that axis in frame F (Cz_F) and a position vector to a point on the plane expressed in the same frame, p_FC, creates the pose of the half space in frame F: X_FC.

Cz_FThe positive z-axis of the canonical frame expressed in frame F. It must be a non-zero vector but need not be unit length.
p_FCA point lying on the half-space's boundary measured and expressed in frame F.
Return values
X_FCThe pose of the canonical half-space in frame F.
std::logic_errorif the normal is close to a zero-vector (e.g., ‖normal_F‖₂ < ε).
