[Bldg-sim] Ecotect camera rotation problem

I do not have Ecotect here, but as far as I know, it makes useage of
Radiance. So if you are able to locate the view settings used when
rendering the view, you can check the camera settings. Usually the
extension of the view settings in Radiance is .vf, I would expect (or
hope) that Ecotect keeps this.
There should be a line inside the view file containing lots of
parameters starting with -v (all these are Radiance's view settings). If
there is a string "-vu X Y Z" (X Y Z being a vector) you can correct the
image alignment. The vector given here is the 3d vector in scene
coordinates that will point towards the upper edge of the 2d image.
In most perspective views and sections, it is -vu 0 0 1 (as +z points up
in the coordinate system used), while in a plan view with north being up
it should be -vu 0 1 0.
Hope this helps. I have no idea about Ecotect support.
