Hi, All, This not exactly a Java 3D problem but I am hoping somebody will have some solution:
We tried the following command on Windows XP machines with 2G memory: java ..... -Xmx1500 but got the error: Error occurred during initialization of VM Could not reserve enough space for object heap But the same command works on Windows 2000 machines with 1.5 G memory. Do we have to call microsoft to get any hint?
