I had a look at that PhotoSketch plugin.
Interesting, but not really very useful. As far as I can tell about the only feature
added not available inside SketchUps own PhotoMatch is the camera calibration, which
should not really be a problem for panographers anyway? It's not a big deal to undistort
your photos automatically before loading into SU. The feature extractor isn't really that
useful I think, as it is much faster to just align it using the built-in tools in SU.
I own and use both SketchUp, ImageModeler, PhotoModeler, PTGui Pro as well as other 3D
programs - and I also make linear panoramas, but I have not found any useful tools for
making long, hires linear panoramas other than Photoshop (or other layer capable paint
programs)...
SketchUp is a great program, but I don't really see it as a suitable program for making
linear panoramas in hi res. SU uses OpenGL and could easily choke when working with 3D
models with lots of hires photo textures on them. There is no blending between
phototextures, so each 'photo' needs to have its own polygon, and you have no real
control on the size of the textures.
For small linear panos it might work fine though, right out of the box (not the free
version though). It will let you render orthographic views of your model, which would
help a lot when there are several levels of depth in the photos.
