In the webinar thread I have posted an update to the Fusion5 export script that has been shipping with Syntheyes 2011. I'll repost this here so it's easier to find in case you are interested.

link to post

Here's what I changed:
  • Support for stereo camera pairs
  • Characters other than alphanumeric letters are invalid in node names and will be replaced by "_"
  • Fixed cross-platform problems for object paths in FBXMesh
  • Added project info to comp's comments tab and footage name to camera's comments
  • Nodes aligned to grid and spaced for tile pictures
  • Create locked cameras to prevent their accidental modifications
  • Disabled clip lists in Loader, fixed length calculation and supported QuickTime
  • Updated input names of 3D tools (SceneInput and Output instead of "Data3D")
  • Generate meshes that are positioned correctly when imported into Fusion.

Of course this script is just provided AS IS. I simply hope it works. It did for me :-)

Thanks. I hope some day we will be able to create wpp or z depth straight from tracked data without creating rough geometry to block the scene in Maya or other packages and then render out these channels to use in Fusion.

Check out Stefan's Sparse Color Fuse. It can generate the depth or WPP pass from a point cloud with no polygonal geometry at all.

Really? Have to look into that...

Speaking of point clouds...

!

Interesting :)

Really? An award for this in 2013? Have they never heard of Photosynth?

How did you do this? by having it interpolate dozens of points?

NukeX also has had something like this for 2 years now.

Yeah, each point is assigned a value based on the corresponding position or color and the position is placed in camera space XY by the point cloud itself.

Thanks. I will try it out on syntheyes generated point cloud.

That's a neat trick for things like aerial shots or a corner pin type situation!
But I can imagine that it won't work so well for things like your water wheel shot (sharp corners, surfaces that occlude other surfaces...). You might be more successful with a tracker mesh that you can export from syntheyes. My new exporter will write objs that are correctly positioned in Fusion (I did my shadow removal tutorial like that). Then you can treat it like your blocked geometry, render a WPP pass from it or combine multiple tracker meshes for occluding objects.

Syntheyes has nice helper tools to block a scene. You can add a zero-weighted tracker at a specific corner of a house for example and by just retracking 3-5 frames, syntheyes will know its 3D position and you can use it to create geometry there.

Either that or IBC wasn't particularly exciting. Or there is something more to this than is visible in the video.

Never heard of that one before - thanks! :)

Good point about occlusion. Probably a poor choice then.
