i’ve got a movinghead and i can control pan and tilt via dmx.
i am trying to map pan/tilt on x/y coordinates.
but it’s not working properly.
i already tried polar node and warppoints (turned source into target) to calculate it.
this is my setup:
the movinghead is moving well. but i have that really heavy arc and i am not able to “draw” a simple quad (straight lines) with the light.
any suggestions could help.
i think it’s just a math problem, which i can not understand :(
We are the art and technology students that Sune is talking about.
We need some help:)
Here is where we are now:
We have a connection between the spotlight (MARTIN MAC 301) and our tracking patch. We have installed the spotlight on the celing. Beside the spotlight we have installed infrared lights and an infrared camera. When people are being tracked we want the spotlight to turn on and stay on the same person for some seconds. It should follow the person.(we have to decide how many seconds).
OK so here we are NOW:
the spotlight goes on when a person is being tracked, but it immediatly turns away again. (it shuts off). It is also flickering. So our issue is how to keep the spotlight on the person for more than one split second?
We have attached a zip file with the tracking and spotlight patch.
We hope you can help - maybe just give us a hint?
And thank you so much for your help earlier!
the patch you attached has all the absolute links, so it results broken here. anyway, after editing xml i saw the patch. Probably you can try another tracking approach (another type of bgsub, i mean).
here you find a thread i started some time ago, with some tools useful for tracking, hope it helps :)
