Pixel History

The NVIDIA Nsight Shader Debugger allows you to inspect which draw events contributed to a pixel’s values up to the currently selected event.

To view Pixel History:

1. Choose a render target. (See Render Targets for details on how to do this.)
   
    
   
2. Zoom in or out of the render target image to make it easier to select a pixel.
   1. Click on the render target image.
   2. Move the scroll wheel on the mouse to zoom in and out.
   3. Click and drag the render target image to move the image up and down, and side to side.
3. Click on the Pick Pixel link. The crosshairs change color.
   
    
   
4. Use the mouse to move the crosshairs over the pixel you want to inspect.
5. Click the mouse on the pixel of interest. The Pixel History page opens, showing pixel information for each draw event that generated a change to that pixel's attributes.
    
   
   

To see the draw call page for a particular draw call, click on the corresponding Draw Call link in the left-hand pane.

To open the source code of the draw call, click on the corresponding Debug Pixel link in the left-hand pane.

Pixel history can only be used when your system is configured for remote debugging.
