3D status map in nagios 3.2.1


Hello Folks,

I am new for nagios and this forum.

My previous nagios server is 3.0b6. There is one option for 3d status map.I upgrade nagios server to 3.2.1.
I installed fresh copy of nagios 3.2.1 on Ubuntu server.All other thing is working fine but there is no option of 3D status map in web interface.

So i want to know where i make mistake or is there any additional configuration in nagios 3.2.1 for 3D status map ??

Any suggestion highly appreciated.
