Blend between cameras


ch3

Recommended Posts

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

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.
