More Realistic Field of View for Panoramas & Default EXE

Reminder: If you encounter any issues with Enscape (including installation problems) or your subscription please reach out to our dedicated support team directly through the Help Center or by using the Support button as detailed here. Thank you for your understanding.
  • I'm staring a new thread on this issue because I think it's important to discuss, and probably easy to implement a solution. The problem is this: The native FOV for panorama images is set too high, which results in a distortion in the image that makes every room or environment seem much larger/deeper than reality. Presenting an unrealistic proportion and depth to clients is unthinkable - especially when dealing with interior spaces.


    This issue is not the result of what kind of QR code or hardware you may be using. While some devices have the ability to tweak FoV, you are NOT actually changing anything in the source image and only further adding to the distortion. Again, the answer is not 'get a better QR code' or 'try another device/cardboard viewer'. The answer is to fix the incorrect FOV setting within Enscape.

    The best way to illustrate this is to show an example! I've put together two images in a Yulio experience:
    The first comes from V-Ray, and has a FOV of about 55°. This is a very close approximation for how most human beings would perceive that office space if they were standing in the real thing.


    The second image is from Enscape, with an FOV of probably 80°. The difference in depth is astonishing, and unrealistic. Those of you that may not do interior architecture + design yourselves may not think it's a big deal but, trust me, incorrectly representing the scale of something in the architecture and design world is a horrible practice and one we try and avoid. The goal here should be to get that FOV correct so that clients aren't thinking their spaces will be significantly larger. Because of how we perceive depth, this problem is usually compounded with even larger volume interior spaces (deeper office environments, ground floor lobby spaces, convention center halls, etc).

    The default exe file FOV experience from Enscape is even more drastic. That FOV for exe files should automatically default at around 55°.

    Here's the link:

    Before looking around, just use the forward/backward arrows for a quick depth comparision. Think of what you're seeing like this: The depth difference at any view is probably around 5' to 8' difference. That's not good.

    I would urge the Enscape development team to strongly consider a new default, or the ability to set the FOV ourselves. Tnx

    landrvr1 , thank you very much for taking the time to share your valuable feedback with us.


    I will definitely be forwarding this to see if we can adjust this for the future, at the moment I don't see reason why it wouldn't make sense to reduce the FoV of our panoramas (or give the option to), maybe there is a valid technical reason behind it though - I'm gonna discuss this internally and let you know in case I have more information to share with you soon.

    I'm having the same issues when exporting panoramas from sketchup. Has this been resolved yet?

    Thanks.

    Not at the moment just yet, I'll get back to both of you in case I have any further news to share regarding this topic. Also, welcome to our forum and thanks a lot for your feedback!

  • This is actually becoming a significant issue. In the current work at home climate, the creation and sharing of fixed point panoramic experiences has increased quite a bit. We've had several comments from customers regarding the distorted POV.

    I make a test with a fov with no deformation to compare both.


    Enscape default fov : https://api2.enscape3d.com/v3/…7c-426a-8fce-db110bd9730f

    good fov (40-45°) : https://kuula.co/post/7FVPN


    After exported the panorama jpg file, i use Pano2vr to adjust the fov or i adjust directly on a external website.
    The problem is that most popular website are not free, or free with several limitation.
    The fact that is i can't use the Enscape Cloud with the default FOV :(.


    Thank you for your attention.

  • Adjusting the FOV after the image has already been generated only causes a different kind of distortion. The incorrect spatial relationship of objects remains the same. It's no different than taking a still photo of a distant subject matter, and cropping everything out but the subject matter and enlarging the image. It will always look odd.

    Thank you everyone for your further feedback. I know it has been a while since you heard from us in this thread, but your additional input has been forwarded and we'll discuss it internally once more - be assured that it's not a forgotten topic but it did fly under the radar, so thanks again for providing your thoughts here!

    WFH means we do not have the luxury of controlling the environment we are presenting in. Trying to explain to clients remotely viewing a walkthrough or panorama fullscreen on an ultrawide (3440x1440) that there is 'distortion' and that this isnt a faithful reproduction of real-world experience is becoming a daily occurence.

    Thank you - I appreciate the valuable feedback.

  • Does this issue affect stereo panoramic jpegs when viewed on oculus, cardboard, etc, in addition to mono panoramas when viewed in a 2D environment? It seems that the panoramic images exported should be field-of-view-less, i.e. 360 degrees flattened out.


    The whole point of VR is provide real-to-life perspective, and if that is not the case it is definitely an issue that needs resolution.
