Camera.ViewportToScreenPoint

Parámetros

Descripción

Transforms position from viewport space into screen space.

Viewport space is normalized and relative to the camera. The bottom-left of the camera is (0,0); the top-right is (1,1). The z position is in world units from the camera.

Screenspace is defined in pixels. The bottom-left of the screen is (0,0); the right-top is (pixelWidth,pixelHeight). The z position is in world units from the camera.

	// Draw an image based on normalized view coordinates
	// rather than pixel positions.
	var bottomPanel: Texture2D;

	function VPToScreenPtExample() {
		var origin = Camera.main.ViewportToScreenPoint(new Vector3(0.25, 0.1, 0));
		var extent = Camera.main.ViewportToScreenPoint(new Vector3(0.5, 0.2, 0));
		
		GUI.DrawTexture(new Rect(origin.x, origin.y, extent.x, extent.y), bottomPanel);
	}
