Foil 21 What does Sharing Mean in Tango?

From Pictorial View of Tango Features with tutorial SIGGRAPH 98 Orlando -- July 19-23 98. by Geoffrey C. Fox


1 For a chat, sharing is clear -- one shares the text typed in by the different users.
2 Now start and share in the same way, one or more of the simple physics applets -- spring or cross-product.
3 The teacher (deemed the master if he or she started it) can move the Position of the spring and the Force and Energy change in response.
  • All applets in the same session follow the behavior of the master
  • Maybe your spring does not follow? Did you join this session or another one? Perhaps you started a new session by clicking on spring icon rather than by highlighting spring session and clicking on join!
  • Note that "slaves" cannot move spring position -- they are meant to gaze in wonder and growing understanding as teacher moves spring and uses video conferencing to wax eloquent about the physical principles
4 In spring case, Tango shares state defining applet -- here the position of the Spring.
