Field of View - Horizontal or Vertical

  • So interesting question:
    I just noticed this as I rarely use the sync view but, when I had the Enscape settings displayed the FOV settings change from horizontal to vertical. Also if you disable the sync view there isn't a way to change it to display to vertical - What is happening here? Is SketchUp using a vertical aspect ratio that I don't see? When I think vertical I'm assumpting a portrait aspect ratio. The output settings via SketchUp are set to screen size which is horizontal.


    Can someone explain this?



    Also small side note:
    I've been holding off on this as I have a reference sheet now but, can we please bring back the focal length settings? I find it frustrating when I have clients ask:

    Client: What lens are you using here
    Artist: You know a 90-degree field of view
    Client:...
    Client:...
    Client: A what?

    Artist: Yeah

    Client: What?
    Artist: Sorry one second I'll convert it.
    Artist: audible clicking typing ah carry the one, times something click-click ahh!
    Artist: Uhhh yeah so it's a 17.925 mm lens
    Client: Okay....Let's look at a 24mm
    Artist: Now?
    Client: Yes.
    Artist: Sure thing uh one second just a moment I need to calculate that...

    Artist: hmm okay so click backspace - backspace okay yes... umm that's not right hmm.. S#@T!

    Artist: yeah I don't know...

    I know this is a bit over the top but In the world of photography no one uses the term FOV - I don't know why it is used here.

    That's all - Cheers!

  • Having proper "camera-y" controls of the rendering w/ features like aperture, lens, exposure, focus would open up quite a bunch of possibilites. I don't like to reference it but TwinMotion does it like that and it's pretty intuitive.

  • So this is still a legit question I'm seeking an answer to.

    I have designers and clients that get really locked in on a view and specific camera lens and when I have to reset a view and I'm met with two opposing FOV I need to properly explain to them what the software is doing.


    A FOV 45 vertical is completely different from a FOV 45 horizontal.


    Please it's been a week and I need some resolution.


    Cheers!

    There is a mention in here of Sketchup using a vertical FoV which comes from OpenGL. I've mostly ignored FoV in Sketchup as it seemed arbitrary when there is no safe frame or way to lock in an aspect ratio. But now it kind of makes sense - as you resize the window vertically, objects get "bigger" since it is keeping the vertical FoV consistent. Versus dragging the frame wider horizontally - it adds space on either side of the object. Which is the opposite of what resizing the Enscape window does.


    Anyway for Enscape purposes I compose everything in the Enscape window with the desired FoV. Create a scene in Sketchup from Enscape and put the FoV in the scene name so when I go back to it I remember to un-sync and change it to the desired value.


    Recreating focal lengths in 3D software seems like kind of an odd carryover for replicating analog measurements which vary anyway depending on the exact lens and camera, but I get the need to communicate w/ those who have more of a photography background. FoV just makes more sense logically as a measurable value from a fixed point.

  • jtubb , pardon the delay - rifkin just above me already gave the correct answer so to speak, SketchUp is indeed using a vertical FoV (which did cause some compatibility problems alongside Enscape a while back too) - There isn't much more I can really add at the moment besides of course forwarding your Feedback as always (regarding implementing focal length back instead of Fov), and I can say that I completely understand this wish as well.


    If any other questions come up regarding this topic please ask ahead of course!

    You can turn on a safe frame / aspect ratio using the advanced camera tools menu.

    It doesn't change the VFOV / HFOV thing, but it can be useful if you are trying to frame shots /create scenes with a final output in mind.



    Funnily enough it actually then brings up all the technicalities of what your virtual image sensor/film stock size is.
