Quaternion::SetRotationMatrix

Defined in: C4Quaternion.h

Converts a 3 × 3 matrix to a quaternion.

Prototype

Quaternion& SetRotationMatrix(const Matrix3D& m);

Quaternion& SetRotationMatrix(const Transform4D& m);

Parameters

`m`	The matrix to convert to a quaternion. For best results, this matrix should be orthogonal.

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. If m is a Transform4D object, then the upper-left 3 × 3 submatrix is used, and the fourth column is ignored.
