The ZNear property of the SceneCamera class specifies the closest distance that the camera can render. This property is crucial for determining the near clipping plane of the camera's view frustum. A typical value for ZNear is around 5. Setting it below 5, and especially below 1, can lead to rendering artifacts such as z-fighting, where two or more objects appear to flicker or fight for visibility due to precision issues in the depth buffer.
To set the ZNear property, simply assign a float value to it. Ensure that the value is appropriate for your scene to avoid rendering issues. For example, if your scene requires rendering very close objects, you might need to adjust this value carefully to balance between rendering quality and performance.
SceneCamera camera = new SceneCamera(); camera.ZNear = 5.0f; // Set the near clipping plane to 5 units // Adjusting ZNear for a specific scenario camera.ZNear = 0.1f; // Be cautious with values below 1 to avoid z-fighting
