My assembly diagrams are all specifically posed so I will have to stick
with 2013.06 for building Mendel90.

programmatic way to get the same view?

No, we changed the camera parameters so that gimbal and vector cameras now
have the same field of view.
Camera handling is likely to change yet again when we get around to using
a real OpenGL framework.
..so using vector cameras, perhaps combined with --viewall and --autocenter
would be recommended.

Note that the actual posing didn’t change, only the FOV, so you should be able to get very similar views by adjusting the distance.

I thought your last change put the FOV back to 45. Was it something
different in 2013.06?

I think there needs to be user control of the FOV to allow complete control
of the camera. Perhaps I can fake that with scale

Actually no, scale has no effect of perspective when you view it at a
distance to make the size the same.

In 2013.06 we didn’t use a FOV, but it was implicitly defined from window aspect ratio and some magic numbers, causing different types of cameras to have different FOVs.

Complete camera control is on the wishlist. Currently pending integration of a real OpenGL rendering framework.

I don't know if it is official, but I found 2015.03 RC3 on the download list.

It has a camera issue of vastly (x4) different sizes when changing between
perspective & orthogonal.

We’re ironing out the remaining fallout from improving the camera FOV stuff.
Will be fixed momentarily.
