Web5 de nov. de 2009 · Hey figured I would throw this out to the collective openframeworks brain. I am trying to figure out how to warp the entire openGL modelview matrix so that I can easily project onto a surface and match the corners to the four corners of the surface I am projecting onto. With Laser Tag I did this by drawing into a texture and then warping … 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. desbt smarty grants

WebOverview The OpenGL hardware-accelerated BCC Warp filter is used for the generation of static or animated image warps. The filter relies on the use of user generated pairs of Adobe After Effects spline mask shapes to define the start and stopping point for the image warp. You can use as many pairs of warp shapes as you like to warp the image.
