It's up to you, some people deal with them all separately or put together pieces as they need. Other options are people will work in cubic but then use a spherical transform to convert just the paint fix back to latlong so your not doing a lot of transforming the original footage back and fourth, only the paint fix. Would projecting onto a sphere would result in a lack of parrallax? so im > guessing you might need geo of the scene ideally? > It's no different then painting rectilinear images with parallax with tracking, corner pins, etc.... Yes, using rough geo helps. ᐧ -- Deke Kincaid Media & Entertainment OEM Development Manager The Foundry Skype: dekekincaid Tel: (310) 399 4555 - Mobile: (310) 883 4313 Web: www.thefoundry.co.uk Email: [email protected] On Sun, Jun 28, 2015 at 7:04 AM, Pat Wong <[email protected]> wrote: > Deke > > Thanks for the reply, yes ive seen these Videos before and whilst i > believe the techniques in the video will work for most situations where the > camera is locked off, Things tend to get a bit more complicated when the > camera plate is moving and there are subjects in the shot, > > > On 28 June 2015 at 01:26, Deke Kincaid <[email protected]> wrote: > >> Pat, to answer your question the workflow with the existing nuke tools >> either: > > 1. breaking the latlong images into six packs with the sphericalTransform >> node.
