Viewport scripting 2005-05-17 - By Alain Laferrière
Back
Hi Patrick,
Although there is no native support for this currently, a possible work-around
would be to expand on the method which I implemented in Xgs_Slate : this is a
XGS ( XSI Graphic Synthesizer ) plugin, which gets evaluated on a per-view
basis to display custom information in 3D views.
The plugin's source code shows how to detect the view for which the plugin is
evaluated, as well as how to get the view OpenGL dimensions and current camera
( used for formatting text to be displayed ).
To achieve what you're interested in :
- take Xgs_Slate, strip out all the code that draws on screen
- use the Execute function to get the view dimensions and camera and store in a
global array ( for all views )
- add a custom command handler to implement your command ( e.g.
"GetViewCameraUnderMouse" )
- "GetViewCameraUnderMouse" command implementation :
- get current mouse coordinates
- compare mouse coordinates with all views ( in global array ) ; detect
which view ( if any ) is under the mouse
- return the view camear name or "None"
You can find the source code for Xgs_Slate on http://www.softimage.com/xsinet.
I suggest you also look at the source code of XSI_UserNormalEditing, for an
example of getting the mouse coordinates and implementing custom commands in a
C++ plugin.
I hope this helps,
Alain

Hi Patrick,
I don't think it is possible to know over what the mouse is "hovering" in XSI.
If you find a way, let me know!!

Hey all,
Is it possible to know, through scripting, which viewport the mouse is
over and what is in that viewport? I'd have to get to the camera that is
displayed in a viewport.
Many thanks,
