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_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
