gl_get_affine_transformation_meta_as_ndc(
meta: VideoAffineTransformationMeta,
): number[]
Retrieves the stored 4x4 affine transformation matrix stored in meta in NDC coordinates. if meta is NULL, an identity matrix is returned.

NDC is a left-handed coordinate system
- x - [-1, 1] - +ve X moves right
- y - [-1, 1] - +ve Y moves up
- z - [-1, 1] - +ve Z moves into
Parameters
