Hi! SketchUp camera match tool defines wrong camera orientation values. See the proof. I will use Photoshop to draw perspective scheme using trigonometry to check it.
So let’s have a rectangular canvas size like 2560x1440 (in pixels) and vertical FOV 30 deg. and so horizontal FOV will be 50,9 deg. Let it the level of horizon line be like x=20 deg. and also I will incline it to 30 deg (z=30 deg). Next, I draw a cube rotated to the camera on 45 deg. You can download my .psd document, I created here guidelines, contours, marked VP and MP (switch it on in Photoshop if it is turned off).
So now let’s try Sketchup matching tool. And we will see that SU defined x like -17.2 deg. and z 31.6 instead of x=20 and z=30. Or maybe I’m something missing up?
