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

@skuven here is the current update - Including my new aiming system. Its really shaping up!

Hi,

On Epson projectors, you need to go into the network settings, then in the "other" section, and activate PJLink ( de-activated by default ).

The other controls are using other protocols, so will work anyway.

Best,

I used PJLink to control my Epson projector (I currently use another method because I find PJLink more limited). I remember that even though I didn't have a password set in the projector's menu, I needed to enter the following password in the PJLink actor: @Panasonic (I saw it on a forum).

I hope this helps.

Best

Hiya

Thank you for this.

I am no where near this level and I was doing an introductory course for some theatre students.

I was trying to get them to see beyond the linear scope of simple playback etc and the video above might have pushed them in a different direction.

cheers

@dusx Yes! That would help me considerably if its not too much trouble for you... thanks!

@eamon i will post a zipped file of everything - quite happy for you to have it. I have a new version I’d like to showcase with working aim logic

That is damn impressive.

I was giving a class today on Isadora and man I would have loved to show them that.....

brilliant.

Very well done.

@skuven

This is pretty cool. 

@juriaan

Yes, using PJ link actors.
