WebThis code needs 3 new functions : computeMatricesFromInputs () reads the keyboard and mouse and computes the Projection and View matrices. This is where all the magic happens. getProjectionMatrix () just returns the computed Projection matrix. getViewMatrix () just returns the computed View matrix. This is just one way to do it, of course. 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.
