[opensource-dev] Return drawable/object at mouse point
I'm writing some code for a research project to log the object at a particular point on the screen (using mouse coordinates). So far I've made use of the LLViewerWindow::cursorIntersect function which seems to work pretty well. However, I can't seem to capture certain things like the sky, clouds, water, etc. Is there a way that I can capture everything being rendered in the scene? I was hoping it is possible to capture a particular drawable being displayed at a given point. Then, I should be able to get the object associated with that drawable as well as the render type. I just haven't figured out an easy way to do that yet. Are there any functions I'm missing, or does anyone have a suggestion as to how I can capture these data? Thanks!

[opensource-dev] Detecting mouse over sky or water
I'm working on a project to track what object is currently rendered at the current mouse screen coordinate. There was a recent thread I found (http://www.mail-archive.com/sl...@lists.secondlife.com/msg04380.html) that highlights the cursorIntersect function in the LLViewerWindow class. That is exactly what I've been using, and it seems to be working just fine. The only problem is that I can't seem to capture sky, clouds, or water. The function just returns with a null value when I'm hovering over any of those objects. I tried changing the depth parameter, but that hasn't helped. I also double checked the gObjectList array, and there are, in fact, sky and water pcodes in there. Does anyone know of any reason why I can't retrieve those objects then? Thanks! Nick P.S. As a follow-up to this challenge, I am also looking to log whether the mouse is hovering over a dialog box (i.e., inventory, map, chat window, etc.). I tried using the cursorIntersectIcon function, but that doesn't seem to be giving me what I want. Any guidance on that would be great too! ___ Policies and (un)subscribe information available here: http://wiki.secondlife.com/wiki/OpenSource-Dev Please read the policies before posting to keep unmoderated posting privileges
Re: [opensource-dev] Detecting mouse over sky or water
Thanks for the tip Jason. Which class are you referring to when you say "touch picking code?" -Original Message- From: Gigs [mailto:gigstagg...@gmail.com] Sent: Wednesday, March 03, 2010 2:27 PM To: Lockwood, Nick Cc: opensource-dev@lists.secondlife.com Subject: Re: [opensource-dev] Detecting mouse over sky or water IIRC the touch picking code can tell you if you touched water sky or terrain. I don't think it's well abstracted though and may need to be moved into a new class. -Jason Lockwood, Nick wrote: > I'm working on a project to track what object is currently rendered at > the current mouse screen coordinate.
