Hi,
I've just recompiled the latest ARToolkit release=20
and downloaded the current version of Glut and DSVL libraries.
I then started the simple.exe example , jsut to test ...
Nothing happen.

I then started my own code, in which I added some=20
other effects than only drawing on the video:=20
displaying the pattern name for example.=20
Surprinsingly, nothing is shown on the video (no=20
cube drawn on the Hiro Patt), but the behaviour=20
of my code triggered when the Hiro Patt is detected is almost correct.

I further investigated this problem by launching the mkpatt.exe.
I can see the video in the frame, but a message=20
is also displayed in the command window:
"argl error: your OpenGl implementation and/or=20
hardware's texturing capabilities are=20
insufficiant to support rectangle texturing.

Any idea what the reason might be ?

I'm working on DELL Latitude D520 laptop (small config, but that small ?)

Thanks in advance
Emmanuel

It is most likely that the report is correct.. plenty of Dell laptops use onboard graphics, without rectangle texture support. Run Gl Extensions Viewer (http://www.realtech-vr.com/glview/) and check. The odd thing is that in ARToolKit 2.72.1, argl falls back to power- of-two texturing if rectangle texturing cannot be supported... so you should still see an image. Can you supply more info on your config? (Toolkit version etc). Phil.
