Hardware gamma
Hardware gamma control will modify the colors of the output before sending it to the display. This will
also affect the depth information that the Visualizer sends to the display, possibly having a negative
impact on the depth effect. A clue that the application is using hardware gamma control is if changing a
brightness or gamma setting from the application’s menu also changes the brightness of the depth map
(see 6.13 on how to display only the depth map).

Application resolution
The resolution at which the application renders is detected by the Visualizer automatically if these
options are set to 0. If auto-detection fails, use this option to override it.

Image input resolution
The application can be forced to render at a different resolution by changing the viewport. This results
in a lower resolution 2D input to the Visualizer. Quality in 2D mode is optimal if the input resolution
is equal to the application resolution. Optimal quality in 3D mode as well as highest performance is
achieved when the input resolution is set to a quarter of the application resolution (both width and
2
If the application has no brightness/gamma setting it is difficult, but still possible to see the effect of it on the
depth. Follow the instructions in section 6.9 to get a correct perspective. If straight lines toward the horizon still
appear bent when looking at the 3D display from a different angle, then this could very well be caused by
hardware gamma.
