Simple example that showcase the device extension VK_KHR_shader_clock.
The app can be controlled using:
| Key | Result |
|---|---|
| H | Toggle heatmap on/off |
| Left arrow | Decrease heatmap scale |
| Right arrow | Increase heatmap scale |
| Up arrow | Decrease iterations |
| Down arrow | Increase iterations |
| Space | Reset settings to default |
This example was inspired by this article.
