If that is your "image" of Umeå, I don't think you have seen Umeå from its
best side...
A CPP file :-)
I know we are coding quite a lot, but I would have expected some more colors
in your image of Umeå!!
Did you forget to attach an image?

Hi All,
One of the tasks bubbling along in the background is support for
distortion correction in osgViewer. osgViewer itself won't provide
the support but will allow you to set up the required cameras and
distortion meshes as custom scene graph elements. This week I
generalised a couple of components in osgViewer, SceneView and Camera
to allow to work, ableit in app hardwired way.
Eventually you'll be able to set this all up from a configuration file
which will specify both the camera set up and the distortion
correction mesh, then in any osgViewer::Viewer app you'll just need to
load the configuration file and your app will be able to support novel
displays without the need for extra distortion correction hardware, or
coding from yourself.
As a proof of concept the osgdistortion example now has an extra code
path that creates 6 RTT Camera's to generate a cube environment map
and one HUD camera for distorion correction all within a single
osgViewer::Viewer. The user of the viewer only sees the result of the
last HUD camera, so it'll feel like you using one fancy camera rather
than 7...
What do the results look like? See attached image of the town of Umea
(thanks for VRLab for the model :-)
The distortion correction here is for a mythical 360 degree projector
at the center of dome, no such beast exists, but the code in
osgdistortion is about proof of concept. Proper math models for the
distortion correction of real physical display configurations will
follow, although not this week.
Robert.
