Hi,

When i executed the simplevrml program, the output is not only upside down but also flipped opposite in other directions. Did i forget to do anything or is this an inherent problem?Can anyone lend me some assistance?I've searched the forum and found few similar cases but they were not replied.

Speaking of which, is there an easy way to flip the image that ARToolKit operates on in the horizontal before processing it? I RTFM but couldn't find anything of relevance except for some windows-driver specific functions. I hope this makes sense.

Hello, Are you working on windows or linux? In my experience, flipping the display horizontal or vertical can be done in the ArVideoOpen(vconf) function. So in that function, you pass a string, in this case called 'vconf', which contains the description of the video format. In my case, my vconf is: char=09=09=09*vconf =3D "flipV,videoHeight=3D480,videoWidth=3D640"; // see = video.h for a list of supported parameters if you want to flip horizontally, add the word 'flipH' in the parameter lis= t. I don't know if this is exclusively for windows. Also, I am not 100% sure if this is the way for the newest version of ARToo= lkit.

I've tried using the vconf string given in the simpleVRML file: arVideoOpen("flipH,flipV,showDlg"); it compiles alright but the image is still upside down. What does it mean by not implemented (yet)??This is found inside video.h=> flipH : flip image horizontally (WARNING: non-optimal performance) * not (yet) implemented --> HAS NO EFFECT IF USED WITHOUT ARTOOLKIT Another question:do i need to change anything(the ARToolkit source code) to do this flipping??

Hi there, What version of ARToolKit? What version of DSVideoLib? Are you sure that you don't have image flipping turned on separately in your camera driver? I have seen this issue on people using Logitech Drivers.. the Logitech camera control program allows you do flip vertically and/or horizontally. If you have this option in your driver, then use it.. it will provide better performance than asking DSVideoLib to do the flipping (via the flipV parameter in the vconf string.) As for the horizontal flipping.. there should be a tick box labelled "flip horizontally" on the Windows WDM capture dialog box which appears when you launch the app. Cheers, Phil.
