CalcLocalTransform()

void CalcLocalTransform	(	const Vector3 &	p_posVec,
		const Vector3 &	p_dirVec,
		const Vector3 &	p_upVec,
		Matrix4 &	p_outMatrix
	)

[AI] Computes a transformation matrix based on a position, direction, and up vector.

[AI]

Parameters

p_posVec	World position vector (translation) to use for transformation. [AI]
p_dirVec	World direction vector (Z axis of the matrix). This will be normalized. [AI]
p_upVec	World up vector (Y axis of the matrix). This will be normalized and orthogonalized. [AI]
p_outMatrix	Output parameter to receive the resulting 4x4 transformation matrix, built from the supplied vectors. [AI]

[AI] The resulting matrix is suitable for orienting/repositioning an object in 3D space: the direction is used for the forward axis, up for vertical axis, and the function ensures all axes are orthogonal and normalized. [AI]
