Linear algebra transforms

rotate(obj[, angle, axis, anchor_point, ...])	Rotate object.
Rx(angle[, degrees])	Generate the \(3\times3\) rotation matrix \(R_x(\theta)\) for a rotation about the \(x\) axis by an angle \(\theta\).
Ry(angle[, degrees])	Generate the \(3\times3\) rotation matrix \(R_y(\theta)\) for a rotation about the \(y\) axis by an angle \(\theta\).
Rz(angle[, degrees])	Generate the \(3\times3\) rotation matrix \(R_z(\theta)\) for a rotation about the \(z\) axis by an angle \(\theta\).
reflection_matrix(v)	Generate reflection matrix that represents reflection of points in a mirror plane defined by normal Vector v.
rotation_matrix([angle, axis, anchor_point, ...])	Generate an \(n\times n\) rotation matrix.
scaling_matrix([s, v])	Return scaling matrix.
transformation_matrix([angle, axis, ...])	Generate an \((n+1)\times(n+1)\) transformation matrix for an affine transformation in \(n\) dimensions.
axis_angle_from_rotation_matrix(rmatrix)	Compute the rotation axis and angle from a rotation matrix.
