If you're using 3.5, include the transforms.inc file and then use the
Center_Trans macro to center your object (actually its bounding box so it may
not look like you want it to look) around the origin.

#include "transforms.inc"
#declare MyPrism=prism{...}

object {MyPrism
    Center_Trans(MyPrism, x+y+z)
}
