Created: 2012–10–09 10:36

Status: Released

Category: Request

From: frankie

Version: 2.2

Released_In: 2.3

Description:

sometimes it would be useful to know if a node is visible or not. This is a request for a tcl command that inputs a viewport and a nodename and it returns whether or not that node is visible in the specified viewport.

If the radius is positive, then it will return "1" if any portion of the radius around the node is visible in the viewport. If the radius is negative, it will return "1" if ALL of the sphere around the node is visible in the viewport. It will return 0 if those conditions aren't met. The syntax is:

doug.load_plugin dsp_nodeview

   dsp_nodeview.isvisible -view view_name -node SSREF -radius 100
   dsp_nodeview.isvisible -view channel#.view_name -node SSREF -radius -400
   dsp_nodeview.isvisible -view display:channel#.view_name -node SSREF -radius -50
