chaging screen resolutions

[hotspur1]

Is there a way to change screen resolution from within Vizard?

I am working in a scenario where I initially want to have higher res (probably SVGA or maybe XGA but when I call Vizard, I need to get resolution down to VGA so I can use my Kaiser HMD. I'd need to set the res back when I am done with my Vizard script.

Are there any calls or workarounds in Vizard for doing this?

Thanks
Andy

Hi Andy,

There isn't any built in function to change the screen resolution within Vizard. However, if you know a little bit of windows programming, it would be very easy to create a Vizard plugin to accomplish this. Here's some windows code that will change the screen resolution to 800x600:

***************************
DEVMODE dmScreenSettings;
memset(&dmScreenSettings,0,sizeof(dmScreenSettings ));
dmScreenSettings.dmSize=sizeof(dmScreenSettings);
dmScreenSettings.dmPelsWidth = 800;
dmScreenSettings.dmPelsHeight = 600;
dmScreenSettings.dmFields=DM_PELSWIDTH|DM_PELSHEIG HT;
ChangeDisplaySettings(&dmScreenSettings,0);
***************************

The following code will return you back to the original resolution:

***************************
ChangeDisplaySettings(NULL,0);
***************************

Good luck!
