Generate the 4x4 transform matrix corresponding to a viewpoint.
Convert a vlc_viewpoint_t into a 4x4 transform matrix with a column-major layout. The transformation is applied as-is. you have to reverse the viewpoint with vlc_viewpoint_reverse first if you want to transform the world.
- 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
