Quaternion::SetRotationMatrix

Defined in: TSQuaternion.h

Converts a 3 × 3 matrix to a quaternion.

Prototype

Quaternion& SetRotationMatrix(const Matrix3D& M);

Parameters

`M`	The matrix to convert to a quaternion.

Description

The SetRotationMatrix function sets the components of a quaternion to values that represent the same rotation as the one represented by the matrix specified by the M parameter.

This function expects the matrix M to be orthogonal and have a determinant of +1. If these conditions are not met, then the results are unlikely to be meaningful.
