Re: GlobalEventSet::fireEvent performance

As you suggest, disabling the global event set seems to be safe. We weren't using the global event set, so I just commented out the call to GlobalEventSet::fireEvent in EventSet::fireEvent. I've entered a report in mantis, and included a link back to this thread. I also entered a report for the only...

GlobalEventSet::fireEvent performance

We've been spending some time optimizing our engine's performance. Using Intel's sampling profiler, we found that GlobalEventSet::fireEvent is the fourth biggest hotspot in our engine. After some investigation, it turns out that the cost of this function is in the string concatenation that builds th...

Re: Derivation of cegui projection matrix

I have made a little progress on getting things working in stereo 3d. There is a note in nvidia's best practices paper ( http://developer.download.nvidia.com/whitepapers/2010/NVIDIA%203D%20Vision%20Automatic.pdf ) that states that scissor clipping is not performed per eye. I happened to notice that ...

Derivation of cegui projection matrix

Hello, I've been trying to reverse engineer the values in the projection matrix created in OgreRenderTarget::updateMatrix and failing. There are a few things that have me stumped so far. 1) The location of non-zero values in the projection matrix don't match those in my (very limited) understanding ...

Re: Render to texture questions

Thanks a lot for the example, it helped tons. What you posted didn't work for me; I believe the combination of Ogre 1.7 RC1, direct3D renderer, and octree scene manager behaves differently then what you tested with. What happens with this combination is that CEGUI::System::renderGUI results in a cal...

Re: Render to texture questions

Hi Thanks for the quick response. What I was planning on doing was during interface creation programmatically creating various images (character previews, animated textures, etc). The names of these images would then be available to interface developers to use anywhere they wanted in the actual inte...

Render to texture questions

Hi, I am trying to make a window which shows a preview of a player's character. My current approach is to create a scene containing that character and render it to a texture. I then take that texture and create a CEGUI imageset and image from it. The last step is to set the Image property of a Stati...

Re: A few issues upgrading to v0.7

Hi,
The good news is that I think your second and fourth issues have been fixed in the cegui svn repository. See viewtopic.php?f=10&t=4357 and http://www.cegui.org.uk/mantis/view.php?id=304 respectively. The bad news is I have no insight on your other problems.

Re: how to not handle mouse event?

The newest version of cegui (0.7.0) modified how events are marked as handled. The changes are described in the "Events and input handling changes" section of http://www.cegui.org.uk/docs/current/porting6to7.html. If you want mouse input that is not over a ui element to be marked as not ha...

Re: Resizing a FrameWindow causes slowdowns

Since I'm using Ogre (1.6.1) and cegui 0.7, I figured I would try out your layout file and see if I experienced the same problems. Even in debug build, I saw no noticeable effect on frame rate while resizing the window. If the drop in framerate is large enough, you could try breaking in the debugger...

Re: Framewindow inner rect problem

I believe I have figured out how to reproduce the problem. It occurs if the framewindow is never sized while visible. In the layout file above, the framewindow's 'Visible' property is set to false, and the window is shown in response to a key press. In case it helps, the following snippet after load...

Re: Framewindow inner rect problem

The interface should be rendering to a viewport target (its using the default constructor of CEGUI::OgreRenderer). I think the frame window is rendering to a texture though because AutoRenderingSurface is true for FrameWindow in the looknfeel file. Changing that property had no effect. The window is...

[Solved] Framewindow inner rect problem

I'm experiencing a problem with frame windows that appears to be inner rect related. When the window is first show, it does not appear to account for the titlebar when calculating the inner rect. If the window is moved and then deactivated the area is closer to correct. Resizing it results in the ex...
