| camera | The Scene view Camera to draw the overlay for. |
Schedules the drawing of a wireframe overlay for a given Scene view Camera.
Note that DrawWireOverlay works only in the Unity Editor, when the Camera.cameraType is set to CameraType.SceneView, and the SceneView.CameraMode.drawMode is set to DrawCameraMode.TexturedWire. If these conditions are not met, calling DrawWireOverlay has no effect.
To draw gizmos on top of the wireframe overlay in your Scene view, call DrawWireOverlay and then call DrawGizmos.
