Demonstrates how to enable HDRFramebuffer mode if available. The render a test scene using a pattern that makes it easy to detect if the display actually enabled HDR mode.
This sample outputs to a HDR screen if supported.
This is a work in progress sample as the currently used tonemapper isn't suited for HDR displays.

- UHD Color for Games
- Implementing HDR in ‘Rise of the Tomb Raider’
- High Dynamic Range Display Development
- Advanced Techniques and Optimization of HDR Color Pipelines
- VDR Follow Up – Tonemapping for HDR Signals

The app can be controlled using:
| Key | Result |
|---|---|
| 1 | Fullscreen linear rendering |
| 2 | Fullscreen tonemapped rendering |
| 3 | Split-screen rendering (default) |
| Q | Decrease exposure |
| E | Increase exposure |
| R | Reset exposure |
| P | Toggle HDR debug pattern on/off |
| A | Strafe left |
| W | Strafe right |
| S | Move forward |
| D | Move backward |
| Right Mouse | Mouse look (hold it) |
| Middle mouse | Reset camera |
