Web29 de jan. de 2011 · Suppose you have a point (0,0) and after the transformation it becomes (0.23,5.6), then you are not directly writing to a pixel in the output image, but a floating point 2d position between pixels. In this case, you could do an “anti-aliasing” kind of method, where you write the weighted average to a neighborhood of, say, 9 pixels. WebThe problem is that the algorithm is not fast enough for me so I decided to change it to OpenGL. After some research, I see that the lookup table texture is the best option for this. I have a set of control points for source image and new positions of them for warp effect. How should I create lookup table texture to get warp effect?
