# NoDraw QML Type

When a NoDraw node is present in a FrameGraph branch, this prevents the renderer from rendering any primitive. More...

## Detailed Description

NoDraw should be used when the FrameGraph needs to set up some render states or clear some buffers without requiring any mesh to be drawn. It has the same effect as having a Qt3DRender::QRenderPassFilter that matches none of available Qt3DRender::QRenderPass instances of the scene without the overhead cost of actually performing the filtering.

When disabled, a NoDraw node won't prevent the scene from being rendered. Toggling the enabled property is therefore a way to make a NoDraw active or inactive.

NoDraw is usually used as a child of a ClearBuffers node to prevent from drawing the scene when there are multiple render passes.

     Viewport {
         CameraSelector {
             ClearBuffers {
                 buffers: ClearBuffers.ColorDepthBuffer
                 NoDraw { } // Prevents from drawing anything
             }
             RenderPassFilter {
                 ...
             }
             RenderPassFilter {
                 ...
             }
         }
     }
