vlc_viewpoint_to_4x4()

void vlc_viewpoint_to_4x4	(	const vlc_viewpoint_t *	vp,
		float *	matrix
	)

Generate the 4x4 transform matrix corresponding to a viewpoint.

Convert a vlc_viewpoint_t into a 4x4 transform matrix with a column-major layout.

Parameters

vp	a valid viewpoint object
matrix	a 4x4-sized array which will contain the matrix data

Column-major matrix multiplication mathematically equal to z_rot * x_rot * y_rot
