Purpose

Facebook allows you too upload a "3d Photo" by uploading a depth map alongside an image. Depth Map must be named [IMAGENAME]_depth. This very bare bones project has a set of scripts + a shader to allow users to take a 3D screenshot at runtime.

Basic Usage

  • Ensure your Game Window is running at a reasonably high resolution.
  • Attach CaptureScreenShot.cs to an object in your scene, and attach DepthImageEffect.cs to your camera. Ensure you assign the DepthImageEffect component to the CaptureScreenShot Component's m_depth property.
  • Choose a reasonable Far Plane distance. You can test this at runtime by enabled the image effect and tweaking the camera's far plane. You want a reasonable gradation of value (contrast gives the effect). Once the Far plane value is solid, set targetFar on the CaptureScreenShot to the ideal value.
  • At runtime, hit space to generate both textures into the Assets folder.
  • Upload both textures to Facebook as normal photos -> Facebook identifies the depth texture and generates the 3D photo automatically!

Notes

Obviously this was very hastily thrown together, but it gets the job done. Hopefully it serves as a great starting point, but don't expect a lot!
