requestRedraw Method

Request that the Viewport redraw its contents on the next frame. This is useful when some state outside of the Viewport's control but affecting its display has changed. For example, if the parameters affecting a screen-space effect applied to this Viewport are modified, the Viewport's contents should be redrawn to reflect the change.

requestRedraw(): void

@note This does not necessarily cause the viewport to recreate its scene, decorations, or anything else - it only guarantees that the contents will be repainted.

Returns - void
