Massive is the premier simulation and visualization solution system for generating and visualizing realistic crowd behaviors and autonomous agent driven animation for a variety of industries, including film, games, television, architecture, transportation, engineering, and robotics. Using Massive, an animator, engineer or robot developer designs characters with a set of actions and reactions to what is going on around them.
The installation manual that comes along with massive is sufficient for a noob to get massive running on your machine. But if you are planning to run massive on a Linux machine, you better go through the Troubleshooting section too. Even after getting the mhost server running you may still get an error “could not open connection” while executing massive from the shell. If u are using Fedora, you will be happy to see the following section under the Troubleshooting section
I am on Fedora and get a “could not open connection” error message when trying to start Massive.
The “could not open connection” error you’re getting is because the X server on Fedora has TCP connections disabled by default. Massive is trying to connect to the X server over TCP and failing. If you add the following line to the [security] section of your /etc/X11/gdm/gdm.conf it should remedy the problem.
But under openSUSE running on KDE, you wont find a gdm installation at all. Hence in order to enable TCP/IP sockets for X11, you need to follow the instructions below.
- Set DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN=”yes” in the /etc/sysconfig/displaymanager file
- Running /sbin/SuSEconfig to propagate that setting
- Restart your display manager through /usr/sbin/rcxdm restart
