View Full Version : NVidia 3d vision, glasses option. Works with LW?

I was looking at the NVidia 3d vision system - which uses active shutter glasses to provide3d on a home PC.
http://www.nvidia.com/object/3d-vision-main.html

I've long liked the idea of seeing my Lightwave models and images in proper 3d rather than nasty red/blue anaglyph, but I am struggling to understand how it works in practice.

Has anyone tried using this in anger?

To be more specific, is it possible to render still or moving 3d images for this system using Lightwave, and if it is possible, how difficult is it? It mentions supporting side-by-side JPG and PNG's, but I have not come across these before...

I've worked on small stereo projects before and had to use them. You plug a receiver to your desktop and the glasses are active. Just don't expect the same vibrance from Imax glasses. Images are darker using these systems. The projects I worked on were created in lightwave 9.6 a few years ago and rendered them using this free stereo camera plugin http://colm.jp/plug/stereo.html where you can render both left and right camera in a single pass. Even works with fprime. In lw 11 this should be easier to setup and render. But if you want full control you can always make a camera rig but you have to render twice. Then just comp them in post to create the stereo from two images. The new 3d displays though are using 8 cameras for stereo effect but don't think there's a consumer level system available.

I don't have the shutter glasses, but I was able to install the stereo software from nVidia. You can set it up to use anaglyph if you just want to see the display options. It does come with a still image viewer. I haven't tried using it for movie clips.

The Liberty3D stereo cam lets you render those side-by-side renders in one shot without having to render the L and R separately and combine them in post. Render times are generally a bit quicker rendering it with the Liberty3D Stereo Cam.

If the nVidia glasses work with YouTube's 3D implementatin, you could use that to watch your videos, but there's got to be a better way than that. At any rate, I made a couple of videos on how to make side-by-side renders for YouTube.

One uses the Liberty3D Stereo Cam http://www.youtube.com/watch?v=liPuvDDWi9U and the other just uses LightWave's standard camera http://www.youtube.com/watch?v=93kF5NyN8pQ

I had some experience with a similar system (it was 12 years ago , and it was state of the art at the time...).I used to do some modelling in Pro/E on a Sgi machine and at the end of the week we had them just for show off...
If you can bear the headache , it looks 3d as promised...
Those were shutter glasses and in the mean time things could be a lot better , but I doubt it.

It's impossible to directly use a stereographic rendering in LightWave (as with most software who's manager it). However in output yes, just use a player like Stereoscopic Player :

Otherwise it just cheating with Jefecheck (free now) by putting the 2 rendered side by side :

PowerDVD is also a good program to display videos and photos in Stereography.

Sony Vegas is wonderfull for video editing and display (it handles the MPO files !, as well as the double flow video). There has been significant progress made on After Effects.


There is also the possibility to force the screen if it has this function, it's very convenient ;)

it'd be dang cool to see stereographic in VPR, could it be possible?...

Theoretically yes but it does not yet exist.

Anaglyph rendering is already present in OPEN-GL, and in W11.5 it will be added to the VPR. But it has not announced for a stereographic render in the VPR.

AhA! I actualy have the cheap version of Vegas! I will definitey have to look infto this.

I really am out of my depth here, but the NVidia system seems to work with games that use OGL - So perhaps it's not out of the question?
It would certainly be a huge help when setting things up to see directly in 3d!

The 2 versions (Studio and Pro) have the same base for the Stereography. In the latest Studio can also create 3D Blu-ray (I am bringed to use both versions).

It's a through, it is also well see even better to use the feature built into the screen (if present) : less artifacts, less resource and work with all software (DirectX or OPEN-GL).
