Hi there,

Thank you for a great tutorial. I have a general question about finding the intrinsic parameters, not limited to this tutorial. When you try to calibrate the camera, how do you account for any variations in focal length that happen as the camera’s focus adjusts? Or does the marker need to always be nearly a constant distance away? I’ve been combing the Internet for an answer to this but so far no one seems to have mentioned it.

I eventually can run the app without the framebuffer error and 501 error. I simply copy the initWithCoder() to initWithFrame() and fixed the 501 error with Kimmy’s suggestion. The remaining part is the camera feed. I read through the comments again and figured out that the CameraTestAppDelegate is not working for iOS 3 and later. Is there any version I can use? I’m developing it with SDK 4.

Thank you!

Hi Roy,

Thank you for your great tutorial. I managed to compile the app and get Failed to make complete framebuffer object 0″ as Roger described. I tried to get the GLGravity code to see how to correctly declare the protocol but the version on Apple is updated. Could you or Roger share how to make do this? I found a file here and tried to copy that to my code but still get the same error. I see there is an initWithFrame() function. If I put this into my 3DGraphicsView.m the framebuffer error disappeared but it’s still in blank screen. More guidance on this is highly appreciated.

Thank you for your work and everybody’s comments. It’s very useful.

I want to compile the coding. for this i downloaded the NyARtoolkit C++ and write the coding in this article. But when i compile it gives me hundreds of errors.
Now i am confused in that, What is cross-compiling and cross-compile NyARToolkit for iPhone’s CPU architecture (Arm) And how can we configure the NyARToolkit library with xcode to work properly.

Thank you

Hi! My project compiles fine and it starts running but is showing a black screen. The problem seems to be that I’m using a newer version of the EAGLView that is used in this project. Anyone can reply me with a link to the good version or send me the files or paste the code here or wathever?

Thank you very much in advance.

Hi Roy, I don’t understand how do the cross-compiling.
I have created a View-Based-Application project for IOS Application in XCode and I have imported your files using drug and drop. Then I have corrected all errors of missing files (EAGLView.h, EAGLView.m and Teapot.h), but when i built the application, Xcode return me warnings (warning: no rule to process file ‘$(PROJECT_DIR)/Classes/NyARToolkit/forLinux/libNyARToolkit/makefile’ of type sourcecode.make for architecture i386) and one error (duplicate symbol _spriteVertices in /Users/ale/NyARToolkit-iPhone/build/NyARToolkit-iPhone.build/Debug-iphonesimulator/NyARToolkit-iPhone.build/Objects-normal/i386/EAGLView.o and /Users/ale/NyARToolkit-iPhone/build/NyARToolkit-iPhone.build/Debug-iphonesimulator/NyARToolkit-iPhone.build/Objects-normal/i386/NyARToolkitCrossCompileAppDelegate.o))…
Is it depends by a wrong cross-compiling???? How i do to resolve???? It’s very important for me!!!!!
Thank you and sorry for my english!!!
