Improving depth buffer precision in AR is crucial for reducing z-fighting, which occurs when two or more surfaces compete for the same pixel depth. This can be achieved by optimizing the near and far clipping planes and using a higher precision depth buffer format. In AR applications, particularly with Unity or Unreal, adjusting these parameters can significantly enhance rendering stability.

<!-- BEGIN COPY / PASTE -->
    // Unity Example: Adjusting Camera Clipping Planes
    Camera.main.nearClipPlane = 0.1f; // Set as far from zero as possible
    Camera.main.farClipPlane = 1000f; // Set as close as necessary
    // Ensure the depth buffer format is set to a higher precision if available
    // (e.g., 24-bit or 32-bit depth buffer)
    <!-- END COPY / PASTE -->

Additional Comment:

Adjust the near clipping plane to be as far from the camera as feasible without clipping important objects.
Set the far clipping plane to the minimum distance required to encompass the scene.
Use a higher precision depth buffer format, such as 24-bit or 32-bit, if supported by the hardware.
Consider using logarithmic depth buffer techniques for large scenes to improve precision across a wide range.
