3.4.6 Other Uses

Some other possibilities for the external interface have come to mind.

• VMD does not yet use Tk for building the forms interface, and there is no script level way to build a new form. Instead, a new form can be built in a remote dpwish shell and the commands sent to VMD. The version of VMD which supports Tk will be available in the summer of '97.
• VMD can be incorporated into data flow applications like Khoros and AVS by building an interface module which translates the data flow messages into VMD functions and vice versa
• VMD can be used as a remote teaching tool as it allows the teacher to view and modify the whole display environment
• Multiple VMD displays can be synchronized by having the vmdlog command   generate a remote procedure call. Assuming the remote connection already exists, this is done with the following command:

        proc vmdlog {text} {
                external send $text
        }

Remember that only the core VMD commands (see Table 11.1) can be logged, so only those are sent to the remote process.
