ch3 Posted November 22, 2016 Share Posted November 22, 2016 I have a bunch of cameras exported from photoScan (photogrammetry app) and I would like to create a master one which can animate between the whole set. What's the best way to get the transform of two cameras, blend between them and drive a different camera? I tried to extract the intrinsics from the alembic export, but didn't manage to make it work. I ended up key-framing the camera in maya with a good old mel script and export it as an alembic. But I was wondering if there is a better way in houdini, with either an FBX or alembic scene from the photogrammetry or any other application. thanks Quote Link to comment Share on other sites More sharing options...
jkunz07 Posted November 22, 2016 Share Posted November 22, 2016 (edited) Houdini has the 'Blend" obj context node. Similar to a Maya blendshape it would blend between two obj level xforms. You could use fetch nodes in obj context to get the different cam xforms going in to a blend node and then have one master cam below the blend node to render with. For more complex situations, sometimes people use chops context to manage a blend a series of different xforms.
