    Presentation, ScaleToFitTransformation

    public interface MatrixTransformation
    extends GlMatrixTransformation
    Specifies a 3x3 transformation Matrix to apply in the vertex shader for each frame.

    The matrix is applied to points given in normalized device coordinates (-1 to 1 on x and y axes). Transformed pixels that are moved outside of the normal device coordinate range are clipped.

    Output frame pixels outside of the transformed input frame will be black.
