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.

CAN WE GET PETER MILNER TO TRAIN SOME OF US FOR A TOKEN ?
Good day, forum members,I was thinking that we could each, if interested, contribute a significant token to give Peter Milner and David to train us virtually in nxt render for Autocad. Am not sure he still uses it but the experience he has spanning over 20 years cannot be underestimated. I wish the forum co-ordinators could look into this. So that more of us will produce realistic renders with the paid version of nxt render and we will be able to encourage other users of other more advanced…See More
LIGHT STREAKS IN ACCURENDER STUDIO
Good day everyone.Does anyone here know how to create light streaks in ACCURENDER studio or in nxt render ? Please share your knowledge with me. Light streaks for interior ceilings in the p.o.p works and under, a t.v console. See More
3D_Replication final
I created this replication of one of Peter Milner's renders, not with AI but with sketchup (with the matchnewphoto tool), autocad and nxtrender.Critics and comments are welcome.
My V.R Panorama Project
Good day everyone.I have been working for sometime on a V.R panorama project. Its a personal project. I used sketchup to model and imported it into arstudio and rendered 6 panorama views at 3k pixel.Check it out here…See More
