Manual of the VRML GUI for the CD Tool This manual describes in detail how to use the VRML GUI for the visualization of the results of the Cell DEVS models This GUI is developed with VRML and Java so it is platform portable and can be run on various environment JDKI l and above is necessary to run this GUI This GUI can be used to visualize the local simulation result drw file and it can be used as visualization GUI in a distributed simulation environment If used as visualization GUI in a distributed simulation environment follow the following steps 1 Open VRML GUI as indicated in this manual 2 Run client interface as indicated in Client Interface manual 3 Use the client interface to select model ma file set the time and the result format such as w5 p2 0 2 Then send to the SERVER 4 The client receives the log file and save to a local log file 5 The client creates the corresponding command such as drawlog mlineal ma clineal llineal log w1 p0 gt 0 gt output 2 and saves it in a bat file 6 The client runs the bat file and then launches the drawlog command to generate a drw file 7 Use the vrml gui to visualize the result The step 4 3 and 6 will be executed automatically by the client 1 Install CosmoPlayer To run this java applet GUI virtual reality software for example CosmoPlayer should be installed in the computer This GUI uses cosmo_win95nt_eng exe which is free and can be d
