How to do Stereoscopic Rendering

Stereoscopic renderingThe process of drawing graphics to the screen (or to a render texture). By default, the main camera in Unity renders its view to the screen. More info

for DirectX11.1’s stereoscopic 3d support.

The minimum requirements are:

  • Windows 10
  • Graphic card that supports DirectX 11.
  • The graphics card driver needs to be set up with stereo support, and you need to use a dual DVI or DisplayPort cable; a single DVI is not enough.

The Stereoscopic checkbox in the Player SettingsA settings manager that lets you set various player-specific options for the final game built by Unity. More info

is strictly for DirectX 11.1’s stereoscopic 3d support. It doesn’t currently use AMD’s quadA primitive object that resembles a plane but its edges are only one unit long, it uses only 4 vertices, and the surface is oriented in the XY plane of the local coordinate space. More info

buffer extension. Make sure that this sample works on your machine. Stereo support works both in fullscreen and windowed mode.

When you launch the game, hold shift to bring up the resolution dialog. There will be a checkbox in the resolution dialog for Stereo3D if a capable display is detected. Regarding the API, there are a few options on CameraA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture.

: stereoEnabled, stereoSeparation, stereoConvergence. Use these to tweak the effect. You will need only one camera in the sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info

, the rendering of the two eyes is handled by those parameters.

Note that this checkbox is not for VR headsets.

  1. Check your setup using this sample.
  2. Check the Stereoscopic Rendering and Use Direct3D 11 checkboxes in the Player Settings.
  3. Publish it as 32-bit and 64-bit applications.
  4. Try it with single camera and double cameras.
  5. Hold Shift when launching the application to see Stereo 3D checkbox in the resolution dialog. The resolution dialog might be suppressed or always enabled depending on the project’s player settings.

Note: Currently, setting Unity to render in linear color space breaks stereoscopic rendering. This appears to be a Direct3D limitation. It also appears that the camera.stereoconvergence param has no effect at all if you have some realtime shadows enabled (in forward rendering). In Deferred Lighting, you will get some shadows, but insconsistent between left & right eye.
