Human EYE fov vs. Human fov
I would like to get your opinion on the problem we face back from old AR3 days and we feel it has not been resolved yet:
- If you google for "human EYE fov", you get plenty of references assuring you that 50mm lens of 35mm camera would do fine.
- If you google for "human fov", you get something like 140deg. horizontally x 90deg. vertically - depends on peripherial vision and other factors...
These two points basically outline the general problem with renderings (and photographs too): to show the scope that is peceived by human observer, you have to use too wide lenses with too much distortion. The result looks unrealistic.
- After some testing, we found that 3x2 field of 6 slightly overlapping renderings made by 50mm lens camera creates (after stitching) quite realistic illusion of what a human can see.
- Unfortunately, there is no tool to automate the task of creating such a "panorama". Neither 3DSlideshow nor animation path allow you to create it...
- You can try to manually create such a sequence and stitch it together by 3rd party software - the result looks quite realistic and convicing.
- Especially on interiors, this method is capable of producing very good results with high informational value. On interiors, everyone struggles on how to set the camera up...
- Obviously, the method, described above, is quite crude. I do not doubt it could be greatly simplified inside the renderng engine - perhaps specific kind of projection...
So I would like to ask: would it be possible to automate this task somehow? What do you think?

Adding a cylindrical projection to WalkAbout would be pretty easy-- this could approximate what are often called "panoramic" photos in point-and-shoot type cameras. Not promising anything-- include some images here to show what you're looking for.

That would be nice...and what about spherical projection? Is it possible? Attached file shows an example of a panorama interior image - how we do it now. It would be perfect to make the process easier

We could try both. Nice image, BTW. We could use some of these for the gallery if you're willing.

This is a remake of one of Peter Milner's scenes. I dont have the file. I photo-matched it in sketchup and rendered in nxt render for autocad.I just retouched it and increased the resolution.

An office render i did recently.Critics and comments are welcome.Its one of the frames of a walkthrough animation i did recently.I used sketchup to model, exported to autocad and rendered with nxt render.
nxt render Course/tutorial
Good day Sir,I want to know the number of people that would be interested in a nxt render course because i plan to create one.Please send me a prompt reply if you are interested.Just sayHi am in.Checkout a walkthrough i just created recently with nxt render for autocad after modelling in sketchup and then post-producing in photoshop.…See More
"Good day Sir,
Hope this message meets you well.
I just completed a short walkthrough of an office.
Its down here
