how to load a model
- select a model name from the "load model..." drop down menu
- the simulation will start automatically
- press "clear" to erase the model
how to build your own models
- select "construct" mode from drop down menu
- select free mass or fixed mass (fixed masses can be dragged but do
not move due to other forces)
- click in main window to create masses or points
- click once on a mass to start drawing a line, click on a second mass
to make a link
- drag to move masses
- to delete masses or links select "delete" from drop down
menu and click on masses or links
how to animate models
- select "simulate" from drop down menu
- you can drag masses while the simulation is running, warning: it can
be tricky to catch a moving mass with the mouse, once caught move the mouse
gently
- modify gravity, friction and strength of springs using the G, F &
K sliders
how to use muscles (see key to the right)
- select the link you want to turn into a muscle by clicking on it in
the main window (a black blob on its mid point shows if it is selected)
- its correspond muscle control bar in the control panel will go black
- drag this bar up to the wave portion to make it expand and contract
according to its position on the wave
- to make the wave move select "forward" "reverse"
or "auto reverse" from the drop down menu while in "simulate"
mode
- by placing muscles at different points along on the wave you can make
walking models (it's rather tricky though)
