Recommended way to support render settings > view > snapshot

what is the recommended way to support this in a 3rd party renderer:

I have tried a few different ways, by scripting the _snapshots command, but this just seems very hacky

@nathanletwory – does raytraced do it via _snapshots, or is there some api I have missed?

The API to use is https://developer.rhino3d.com/api/rhinocommon/rhino.render.rendersourceview/rendersourceview

This you can use in the plugin overrides for Render or RenderView implementation of your plugin.

protected override Result Render(RhinoDoc doc, RunMode mode, bool fastPreview)
    {
      Rectangle fullSize = new Rectangle(new Point(0, 0), RenderPipeline.RenderSize(doc, true));
      return RenderWithCycles(doc, mode, fullSize, true, fastPreview);
    }

    protected override Result RenderWindow(RhinoDoc doc, RunMode mode, bool fastPreview, RhinoView view, Rectangle rect, bool inWindow, bool blowup)
    {
      return RenderWithCycles(doc, mode, rect, inWindow, fastPreview);
    }

    private Result RenderWithCycles(RhinoDoc doc, RunMode mode, Rectangle rect, bool inWindow, bool fastPreview)
    {
      var rc = RenderPipeline.RenderReturnCode.InternalError;
      using (var rsv = new RenderSourceView(doc))
      {
        ViewInfo vi = rsv.GetViewInfo();
        if (vi == null)
          return Result.Failure;

        {
          foreach (var vw in doc.Views)
          {
            try
            {
              // pausing any running realtime displays
              if (vw != null && vw.RealtimeDisplayMode != null)
              {
                vw.RealtimeDisplayMode.Paused = true;
              }
            }
            catch (Exception)
            {
              // pass
            }
          }
        }

        // set up your renderer, pass it on the vi you found.

    }
