glGetAffineTransformationMetaAsNdc

fnvoid glGetAffineTransformationMetaAsNdc(gstvideo.video_affine_transformation_meta.VideoAffineTransformationMeta meta, ref float[] matrix) nothrow

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

    metaa #GstVideoAffineTransformationMeta
    matrixresult of the 4x4 matrix
