The .m3g file that you will need is called pogoroo.m3g . You can find it at the following path:
<WTK 2.2 inst. dir.>/apps/Demo3D/res/com/superscape/m3g/wtksamples/pogoroo/content
Copy this .m3g file to the res directory of the RMMIDlet project.
Now build and run the MIDlet. You will see a 3D kangaroo jumping up and down in front
of you. Use the navigation keys on the phone emulator to move the camera around the kangaroo's
world. Figure 15-10 shows the RMMIDlet in action.
Figure 15-10. Interacting with a retained mode 3D world
The custom GameCanvas subclass in this MIDlet is called RetainedCanvas . The source code
for RetainedCanvas is shown in Listing 15-4.
