How to warp a video mapping
-
Hi All - I have done lots of mapping in my time, but now I'm stuck. I'm projecting a thin vertical video of water/waves onto a 600 cm diameter vertical column using a short throw projector. Using IzzyMap of course... I want the waves more or less "level" across the column and the top and bottom of the thin video rounded to appear to wrap the column. I have used composite on the input for the rounded without luck and tried the grid setting for leveling. I have used just a few grid points thinking moving one might warp the rest of the points, but that didn't seem to work. I tried using 25 points on the long, vertical side and 4 on the horizontal and that didn't seem to work well at all. The bezier handles are so small and white, while my video is very light too. I made a dark grid image to test but I can't get that to warp the way I want it to.
Is there a way of using the grid to warp a column? For what it's worth, I have watched the guru session on mapping several times and read all there is on the Troika website on mapping too. Sorry to be dense and looking forward to any suggestions! - John
