Stereoscopic Red/Blue Glasses

Hi guys!

I know that today we have much better technologies in UE4 (such Oculus), but the company that I work was making a little advergame to use with the old R/B 3D glasses.
So I came to show the process of what we manage to do for the case that someones out there decide to make to.
We think in two techniques, but this have the best results, but lower quality… So we have to think a little more hehehe.

Here’s the first result…

And the process…

We create 2 SceneCapture2DCamera to simulate the eyes, and 2 Textures RenderToTarget2D…

And within a 3D Camera we put a Post Process Material in the Blendables Slot that separate the channels of the two render textures and append then together in the final render.

The performance seam to be the same, but the quality was lower than the normal render of the camera.
We have to try to increase the quality, size of the render targets or whatever solution you guys can manage to help us… eheheh

Thanks

I’m interested in Anaglyph 3D as optional display feature in addition to Oculus support. 3D graphics cards provide drivers for it. A procedural stereoscopic technique would provide another option in the arsenal.

I’ve previously experimented with dynamic stereoscopic techniques. Most revolved around the idea of using two cameras to represent Left/Right Eye, alternating between the two frame renders, updating the 58 FPS (24 FPS film grade). In my opinion, Depth Focus Adjustment plays a role in natural vision, and is better suited for ‘moving pictures’ vs a static image. I simulated auto Depth Focus by calculating the distance between object center of viewing frustum and cameras using a line of sight algo, adjusting the Left Right Cameras spacing and yaw angle. Finally, I adjusted RGB Channels of each Left/Right Frame display for tint balance between Red/Cyan, Magenta/Green, Red/Green combination. I personally feel Anaglyph 3D is harder on the eyes, then other techniques using Full Color.
