I’m working on developing a fire tracking system for adding trails to fire spinning performances in realtime. I have a proof of concept in VVVV that has worked ok at a couple of gigs (video below), but the performance has been a bit inconsistent so I’m thinking of making a version in TouchDesigner to see which programme is most suited to this kind of setup. I’ve heard a lot of good things about TD’s handling of high definition video.
Unfortunately, I can’t get my Avermedia HD c985 capture card to stream video in TD with the directshow(WDM) video driver, despite it working with VVVV’s DShow9 video streaming nodes. I just get an “Error: Unable to connect to device.” message and nothing else. Is there anything I can do to get it running?
It’s a major impediment to testing the relative merits of TD for this kind of setup, but eventually I’m planning to buy dedicated hardware if I can get reliable performance from software, which leads me to my second question. I’m not really familiar with specialised computer vision cameras, so can anyone suggest a pair of cameras that are capable of reliably streaming uncompressed HD video into TD at 30 or 60fps? (Low light performance is a bonus.) I need one for untreated video and one that I can filter to only accept IR light so I can isolate fire, and ideally I’d like to be able to mount them so they have as similar a field of view as possible.
Thanks in advance! TouchDesigner looks like potentially epic software and I’m really looking forward to playing with it.
