Hello all,

In my server-client application(C++) I use VTK for streamline creating. I use UDP for server-client communication due to broadcasting reasong. However, since vtk files are more than 65 kb. I cant send them at once.

What is the best practice to send a vtk file from server to client.

This is a shared memory application. The clients have the same memory access. Currently I write VTK out and read back but its inefficient.
