// LFSGlass.cxx - Network interface program to send data to display processor over LAN
|
||
|
|
//
|
||
|
|
// Created by: J. Wojnaroski -- castle@mminternet.com
|
||
|
|
// Date: 21 Nov 2001
|
||
|
|
//
|
||
|
|
// Extended from original network code developed by C. Olson
|
||
|
|
//
|
||
|
|
// Modified 12/02/01 - Update engine structure for multi-engine models
|
||
|
|
// - Added data preamble to id msg types
|
||
|
|
//
|
||
|
|
// Modified 01/23/02 - Converted portions of the Engine and Gear accesssors to properties
|
||
|
|
// - Removed data from navigation functions. Glass provides own nav functions
|
||
|
|
//
|
||
|
|
// Modified 03/05/03 - Modified to reduce need to search property tree for each node per frame
