[Nuke-users] Zeroing a camera position
Hi Easy when you know how I expect, but is there an easy way to null/zero a moving camera at a specific frame, like a reference frame in a tracker. At the moment I am using 4 axis to 1) set back to origin in translate (easy) 2) rotate Z back 3) rotate Y back 4) rotate X back. I then end up with a zero'd camera at that frame so I can add another axis to match the position of another camera. I've tried this in one node but cant do it and tried reversing transform/ rotate orders, but couldn't get it to work (yet) The above works but seems awkward and makes me feel thick. (but is the 3D equivalent of how I would invert a serise of tranforms pre the invert button) Howard ___ Nuke-users mailing list Nuke-users@support.thefoundry.co.uk, http://forums.thefoundry.co.uk/ http://support.thefoundry.co.uk/cgi-bin/mailman/listinfo/nuke-users
Re: [Nuke-users] Zeroing a camera position
Ok managed to get to 2 nodes 1) set back to origin in translate (easy) 2) invert rotate order and negate rotation Howard From: Howard Jones mrhowardjo...@yahoo.com To: Nuke user discussion nuke-users@support.thefoundry.co.uk Sent: Thursday, 11 August 2011, 12:59 Subject: [Nuke-users] Zeroing a camera position Hi Easy when you know how I expect, but is there an easy way to null/zero a moving camera at a specific frame, like a reference frame in a tracker.

Hi Ok I thought I had tried this anyway but answering my own question reversing (source) SRT and XYZ to TRS and ZYX with negated values does it. in one node (I'm sure I tried that, I'm sure I did...)

Re: [Nuke-users] Zeroing a camera position
You can go to the frame you want and delete the animation. Or there's a little expression you can use to choose the reference frame. I think it's on one of the tips and tricks tutorials on the foundry website.
