public static float CalculateLOD(Vector3 position, float radius)
Parameters
Returns
Type | Description |
|---|---|
| float | Returns a value between 0 and 1 that represents the level of detail for the gizmo. |
Remarks
A return value of 0 indicates the gizmo is not visible. The gizmo might not be visible because it is too small on the screen or because it is outside of the Scene view camera frustum. The return value is quantized to eighths to reduce the number of produced batches. This can be further controlled with the 'Fade Gizmos' options in the Gizmos menu.
Examples
using UnityEngine;public class MyLODedComponent : MonoBehaviour{ // Draw a blue sphere at the transform's position, fading out as it gets further away private void OnDrawGizmos() { float lod = Gizmos.CalculateLOD(transform.position, 1); // Cull any gizmos that are too small or off screen if (lod == 0.0f) return; // Fade the gizmos out so that they don't pop in and out when scrolling around the scene Gizmos.color = Color.blue * lod; Gizmos.DrawSphere(transform.position, 1); }}
