public interface MatrixTransformation extends GlMatrixTransformation
Specifies a 3x3 transformationMatrix
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, with alpha = 0 if applicable.
