Camera - FOV = H unchecked

tomasz

I have found a model that has a camera that somehow has FOV calculated in non standard way.
When investigated deeper using Sketchup.send_action(10624) I realized that the FOV=H is unchecked, which is not default way SU calculates FOV.
Can we somehow set the checkbox back to default state? Can we read the value(s) from the 'Camera' window?

I have fund out that when I manually, in the Ruby Console, set 'active_view.aspect_ratio' to value != 0 and then Sketchup.active_model.active_view.camera.aspect_ratio=0.0
the Fov = H is being restored to default state.

Unfortunately I have hard time doing it from Ruby, even when:

					Sketchup.active_model.active_view.camera.aspect_ratio=1.5
					Sketchup.active_model.active_view.invalidate
					Sketchup.active_model.active_view.camera.aspect_ratio=0

I noticed the same problem some time ago. There is no way of know if SU calculates the FOV vertically or horizontally.
I think that when you set the aspect ratio to be larger than the viewport aspect ratio it jumps from V to H. But I have no idea if it's actually the case. Nor have I found if one can detect if the toggle is done manually via that debug window.

And I was in fact looking at the same problem yesterday - but got no further.

I've also been digging around in this arena recently, but I had not noticed that some models could be altered and saved to use horizontal FOV.... That could mess things up.

Ruby just nees more methods wrapped. On the C++ SDK's ISkpCamera, you have:


virtual HRESULT STDMETHODCALLTYPE 
    get_FieldOfViewIsHeight(/*[out]*/ BOOL *pVal) = 0;

That would be a great request. I know just the people to contact

Also throw in a mention of the camera shifting that occur at times when using camera.aspect_ratio...
