True 3D or stereo viewing assumes that we have two eyes which are at some distance of each other. One eye sees the picture from a slightly different angle than the other one. The brain finally fuses the two separate pictures into the final picture we perceive.

If you look at an object in the distance, like a mountain, your eyes are parallel, the object is too far away. If the object is near, say a pencil 20 cm or 8 inches from your eyes, your eyes turn inwards towards the nose, more so the nearer the pencil comes to the eyes. The “toe-in” angle is the angle the eyes depart from looking straight on and parallel and turn inward.

The brain uses this angle (apart from other cues) to create a stereo image. For us humans, this is all fixed at the distance between the eyes, which is about 6.5 cm or about 2-3/4 inches or so. We can create pictures that are taken at a greater distance than the eye distance. We get a 3D effect still farther away but we perceive it as miniature - we are giants.

We can also cheat a bit by making the “inter-eye” distance larger in relation to the distance of the object and move the camera angle inwards in an unnatural way - toe-in - and give the brain a bit to ponder how to interpret what it sees.

I hope this helps for a start.

There should be one called “P40_ALS_targeting_video1” - although it is possible the names might have changed during the QA process… that happens sometimes.

Horo’s perspective offers a more technical view for the technically minded.  My vidoes are aimed more at the test files and should present a more hands on approach.

Because anaglyph’s are a bit of a hand full - that is the reason for so many videos.

Edit:  Failing that I could always make another video and upload it to youtube, if you email with a scene you are trying to anaglypherize I can make it the topic of that video and tailor it so suit - if you fancy that idea?

grinhey guys ,could you bear with me and answer one ridiculous question- what is the path, i.e.- c-drive>content>whatever for installing the “true 3D” plugin or whatever we are calling it? not the same or is it, as the bryce install? windows 8 SEEMED to offer a default path when i used the installer but i cant remember and i would love to fire this thing up.

If you don’t know where you’ve installed it - the path depends on what option you have selected, the easiest thing to do, I reckon, is search your computer for some of the installed files and then you can discover the path.

Try searching for any of the following for example.

ALS_Practical.pdf
Anaglyph_QTVR_Panoramas.mp4
Cubetrick11.br7 (or .bmp)
Approximator.html

Find any of these files (and I’m guessing there are not an abundance of files with these names on your HD) and you have found were you installed your content.

thanks for the quick response, truth is i havent even started install , my first package is still just sitting there asking me to choose a path and there’s no default one offered, ive been working on a mac and done tons of this (even easier with the new install manager) but the PC install just eludes, my head is hung in shame!

Oh well, in that case, what I do is install to desktop and that way I can find things.  Maybe this is wrong.  My desktop is very cluttered.  But I can find things!

It’s easy on the PC as well. I usually do the first unpacking to a folder which I name “xxx” and then I see what I got and where things belong. Some parts need to be in a specific folder under the main folder where Bryce is installed, other stuff can be anywhere - provided you can find it later.

As far as stuff is concerned that needs to be in a specific location, this PDF http://www.horo.ch/docs/mine/pdf/BryceContent_v4.pdf should be of help.

David, Does the stereoscopic panorama setup produce one left and one right colour image before being converted to red/cyan. Also is the 3d produced from multiple angles which are stitched?  I’m looking for full colour spherical stereoscopic panoramas for google cardboard VR.

Using the panoramic render approach uses coloured lenses, the colour could be removed from the lenses to create untinted images.

Then there is the conceptual questions… It could be made to produce a “left” and a “right” image.  But in a 360 panorama this has a rather awkward meaning.  The panorama lens works by creating an offset for each infinitesimal slice of rotation, so when facing “north” the left offset is “west” and when looking “east” the left offset is “north”.  And so on for every vertical slice of rotation.  The right lens creates a complimentary offset.  This works with left right separation (in the example given using colour)  when viewed in the long/lat projection, but how it would work in any other circumstance I do not know.

No “stitching” is required for the panoramic approach since Bryce already has a panoramic camera.

Weird things happen at the poles, as I recall… this is something Horo has encountered in his experiments, I’m a bit hazy on that, mayhap he will join in and jog my memory?

Hi David,  thanks for that. No stitching sounds great, I understand the stereoscopic panorama requirements and there is not alot of 3d renderers can do it, Ive did some using multiple twin cameras in Carara but they need stitching in other software.
What I need is 2 panoramic images of the left and right view. Is your plugin able to separate the left and right panoramas?
With the 2 images I can use in my phone in the stereosphers app with the google cardboard VR kit and look all round the scene like virtuality reality.  If Bryce can output whole stereoscopic panoramas it could be used for short VR animations as well.
Cheers

Well it is not so much a plug-in as a lens that fits around the Bryce camera.  I loaded in the lens, it has three channels a left lens and right lens and a mixer (which is just used to give a vague guide as to output).  If you switch to the left lens channel and set the transparency colour to white and render you can have one full colour “left” channel and then do the same for the other side and you have a “right” channel.  Normally you would leave them tinted for the 3D viewing glasses.  So I can’t comment about anything beyond that you can separate the two views and have them in colour.  It also seems from my notes that I tested it with the spherical mapper at some point - but I’m sure there’s something that happens at the poles that is unusual.

Horo’s the one that made the QTVR’s, and indeed I see there is a video and PDF on this topic with the product.  So that might also help.

How familiar are you with Bryce?

@gssev - provided you have Apple QuickTime installed on your computer, you can save an ineractive QuickTime Virtual Reality (QTVR) movie directly out of Bryce. For cylindrical QTVR (Bryce cannot do cubical), at least QTVR v4 should run - or any newer version.

I did indeed photographic tonemapped spherical panorama HDRI anaglyph QTVRs. Cylinders are no problem, it is as if you would turn around when you move the QTVR left and right. The problem is the zenith and nadir if doing a spherical (or cubical) anaglyph. If you look up, you can only rotate 180° then left and right swap and things get weird. You can use the anaglyph glasses the other way around for the second 180°. Luckily, if you have an uniform sky, i.e. no clouds in the zenith (or no cable supports on the ceiling) and a meadow on the ground (or a simple floor without patterns), a cylindrical QTVR anaglyph can work without the weird feeling.

I know Bryce well but know it has powerful features that I have not used much because of the rendering times but if this renders a set of left and right panoramas in one render then I will use bryce more as I’ve always liked its renders. I think I’ll just buy the pack and try it. There might be some more questions if I get stuck. If you have fast enough mobile phone you should try VR with it with your amazing Bryce Scenery - its like being in a different world.

Ok I bought it, Downloading as well but will have to wait until later to try it out. Will let you know how it goes.
I shouldn’t need QTVR as I can load a spherical map into my phone and rename it PANO_something or into stereophoto maker and see it there on PC . Might be able to embeded it on here?

It worked great, genius method for getting left/right separation, just did some basic test scenes and tried it in my phone with cardboard kit. I’ll do a more complex hi res one next. Wonder if this is possible in Carrara?. Many thanks its gave a new interest in Bryce for me.
