I am very new on java/android, just worked with processing before. Therefore all those packages, sources, libs are really a problem for me. Right now I would like to load an .obj file using the min3d library. The problem is, that i want to display the .obj on the commmander 3d tablet. Therefore I downloaded an working example for the tablet with a stereoscopic 3d renderer class from this SDK no need to log in. In the package, where in my example cubes are generated, i would like to instead load the .obj. But I get an activity error. I am not sure, if the .obj is found, but i think it should, because if i only load it and do not parse it, i don't get an error. But if I start to parse: "parser.parse();" then the mess begins. The .obj is in this folders: SampleActivity > res > raw > camaro_obj. The next 3 lines aftzer the parse i already uncommented, because at first this should work. But i know already, that the appChild is not avaible. This will be the next problem. Below is the code of the package, the console and the logCat. THANK YOU VERY MUCH!!! best Markus!
