I have a simple sketch using Open3D and when I export as applet I just get a white rectangle. I changed it to P3D and it still doesn't work. I can, however, get a really simple test sketch working as an applet. So my question is, how do I go about debugging? What do I need to look out for with 3D as an applet? Is there anything I shouldn't be using? I'm using 2 dimensional String arrays and a lot of calls to translate() to create my 3D sketch. Is that likely to be an issue?
