I using the system in my projects and wish that all developers include the correct Stereo 3D system in their great projects and S3D users no more feel pain using 3rd party abandoned injector drivers like iZ3D, Tridef(DDD), 3D Vision, etc with the incorrect setting system, wrong depth effects, and risk to be banned in online gaming.
Also, production of 3D Monitors and TVs should be returned with 4K OLED horizontal interleaved method - is a must-have. Because VR HMD’s is not a replacement of a monitor, it’s an addition, and not so comfortable as monitor + light glasses. I spent many thousands of hours in VR with my Zalman glasses and LG D2342P monitor(horizontal interleaved method Cinema 3D) sometimes gaming many days nonstop over 12 hours per day, I know what I’m talking about.
While research render methods and testing I found how to increase performance:
If OnRenderImage function(even empty) exist in script. +2.6%
Set projection matrix for Left/Right cameras instead of using Physical CameraLens Shift. +2%
Set Zero projection matrix of Main camera or near plane to -1 in Scriptable Render Pipeline. + 4.4%
Set Render Texture format from Default to DefaultHDR. + 2%
Set Render Texture format from DefaultHDR to RGB111110Float. + 1%
In total +12.3% of fps in Unity’s 3D+Extras demo scene and 19.3% in my project as a bonus.
Also Don't Clear flag for the background is slower than leave default Skybox or Color.
Post-process effects: Color Grading, Bloom, Motion Blur, Vignette, Ambient Occlusion, Depth Of Field, Temporal Anti-aliasing.
Run via 3DWE.exe for Fullscreen Windowed mode with VSync or 3DWE.exe - Exclusive Fullscreen_noVSync for Exclusive Fullscreen mode without VSync.
Key Controls: W,S,A,D moving, Q,E down/up Tab - hide/show Stereo3D settings panel * On/Off S3D, Ctrl + * swap left-right cameras +,- Field Of View, Ctrl + +,-`` custom Virtual IPD when unchecked Match User IPD
All above keys + Left Shift for faster changes Mouse Look around Esc exit
When launch, Monitor’s Pixels Per Inch(PPI) will be autodetected and precision screen width will be calculated,
as result - settings will be in real millimeters so you don’t need to set PPI or Pixel Pitch manually, set it only if PPI incorrect.
Set User IPD to your own interpupillary distance(IPD) for a realistic view with infinity S3D depth.
Or set User IPD lower than your own IPD for close distance max depth(aquarium back wall effect).
Uncheck Match user IPD and set Virtual IPD(Cameras IPD in the virtual world) larger than your own IPD for toy world effect and vise versa.
With realistic IPD’s Screen Distance will show how far from the screen your eyes should be(camera’s point) where Real and Virtual FOV will match and you get a 100% realistic view. (Very important for Vehicle Simulators).
Hi there!
Thank you very much for releasing this!
I just unearthed my Philips 4k 3DTV with passive stereoscopic 3D and I will be implementing stereoscopic 3D support for my game (work in progress).
I made my own stereoscopic camera system a long time ago, but yours seems more polished.
My system just rendered to 2 cameras, one for each eye, with a shifted camera matrix each.
Are you doing it like that too?
The problem with this approach is that Unity will have to render the whole scene twice, instead of processing it a single time and rendering on both sides at once:
There are more sophisticated ways to do that that will render much faster, but require the use of the XR framework:
As I said, I just used the first method.
I guess you are using this method too, isn’t it?
This is great work.
Do you have any idea how to make Clone Mode 3D Stereo output? This is where the Windows Desktop is set to “CLONE or Mirror” and not extended desktop. Nvidia Control Panel is set to CloneMode 3D also. I am using HDRP so no OpenGL option. Wondering if there is a way to get Clone Mode and secondarily active 3D mode? I’m afraid of using the DirectX 11.x option because I hope to use DirectX 12.x with Raytracing for the project eventually.
