The best advice I can give is to head here for some brilliant tutorials on opengl on the iphone. Read the tutorials, download the source files and you’ll quickly figure out what all this is about and solve the issues you are having:

Does anyone have a complete example project source? Not just the classes etc..

I’m having the same problem as FlimFlam. I can’t change delegates at runtime. Googled it everywhere , i’ll keep on the net trying to look for an answer, but if you can share some light i’l appreciate it a lot.

FlimFlam,

Can you please elaborate on exactly what you did?

I think I am stuck at the same point you were,

glView.delegate = self;
glView.animationInterval = 1.0 / kRenderingFrequency;

are both giving errors about not a structure or union

I got this working! My issue’s were just my lack of knowledge about delegates and how to implement them correctly, but worked through it and figured it out.

Now…does anyone know how to get my own marker in there? I’ve created the marker, changed all references to the old patt.hiro to my patt.metro marker and yet it still only looks for the patt.hiro marker?! Anyone got any nuggets of info that might help me out?

Cheers

Hello,

i tried to compile the NyArtToolkit and all your code, but i got only Warnings and 135 Errors, it seem like the cross-compiling doesn’t work. Can you please describe how to compile the NyArtToolkit for the Iphone?

Keep in mind that when you rename the class to 3DGraphicsView – XCode will automatically change it to _DGraphicsView, since you can’t have a number as the first letter of a class. Perhaps this is the problem.

Brilliant stuff Roy – but I’ve been really struggling today to get this implemented. And it’s get to be in my 3dGraphicsView where I am going wrong. Am I right in using GLGravityView.h / .m – I’ve changed there names to 3dGraphicsView to avoid conflict and then added the protocol at the end of the header file?

I’ve learnt a lot implementing this so far but seem to be falling at the final hurdle.

Dear Roy,

I think your work is amazing, however I don’t know how to implement it, actually I just need the marker detect part, so what should I do??

I think I managed to solve the issue, I didn’t declare the delegate properly in the 3dGraphicsView header file or so it seemed.

Now it compiles fine, yet I don’t see anything when the app starts. No camera-feed, no nothing. Just a black screen with a gray statusbar which shouldn’t even be there.
The thing is, when I redirect the delegate file in Mainwindow.xib back to CameraTestAppDelegate I DO get a camera feed.

Also, you mention some posts before that the default delegate file should be NyARToolKitDelegateApp, however I don’t ee such a file in your source code. There’s only a NyARToolKitCrossCompileAppDelegate , is this the file you mention or am I missing some files?

Sorry to bother with all these questions, it’s just rather important for me to get a demo of this working for my exam next week
