Been a while since I last used AppGameKit so am a bit rusty. Here is AppGameKit code for Mandelbulb (arrow keys at moment). Camera needs more work. DIMEN of 128 causes program to bomb out unlike DBPro, but is ok with values 32 and 64. [edit]- DIMEN 128 works better in x64 AGKStudio, but unable to move camera around , lots of "not responding"

SetWindowTitle( "MandelBulb v0.1" )

// set display properties
SetVirtualResolution( 1024, 768 ) // doesn't have to match the window
SetOrientationAllowed( 1, 1, 1, 1 ) // allow both portrait and landscape on mobile devices
