Hello all, I am trying to do something which should be fairly easy: I am trying to see a circle that let's through an image that is behind it. (As if through a telescope...) So my attempt so far consists of texturing this image into a circle and compensate changes in translation and size of the circle with the pix_coordinate object. I have managed to do this with rectangles and triangles, but can't a find a way around circles. The main idea is the next:
pix_image| pix_texture coordinate-mess | / pix_coordinate | rotateXYZ | translateXYZ | circle The coordinate message has this behaviour: -the 1st two floats don't have any effect. -the 3rd one compresses/expands left-right, -the 4th one compresses/expands up-down, -the 5th doesn't do anything, -the 6th one seems to offest the vertical compression/expanssion -any succesive floats have no effect. So my problem is that without any horixontal offest i can't compensate for size/transaltion values. If i had that i think i could do some math to do this.... Anyone has any suggestions? Is this the wrong approach?? I am attaching the patch if anyone want's to test this and I am also attaching an example of how i am compensating this for a polygon 3 best, J -- Jaime E Oliver LR [EMAIL PROTECTED] www.realidadvisual.org/jaimeoliver www-crca.ucsd.edu/ www.realidadvisual.org 9168 Regents Rd.
