MOVE EXAMPLES

A move consists of an equation or a set of equations with a range. From Math Moves you will remember that an equation(s) can be Cartesian(x, y, z), Spherical(r, theta, phi), or Cylindrical(r, theta, z). Here are a few examples:

1. SIMPLE CHANGES CAN HAVE COMPLEX RESULTS:
   1. Use simple cosine and sine funtions to create a circle.
   1. Click the Reset View button in the bottom of the window to clear the paths and jump to origin (this button will also quit ring tracks).
   2. Click the Move tab.
   3. Do not load a move; we are creating a new move.
   4. Enter From t = 0 to 2/3Pi (This range is necessary to make one complete circle).
   5. Select Cartesian.
   6. Enter x(t) = cos (3t).
   7. Enter y(t) = sin (3t).
   8. Enter z(t) = 0.
   9. Click Move and watch!
   10. Move your fish around the environment so you can see the trail. See Navigation for help.

   

   
   
   1. By changing the y component slightly you can break the circle.
   1. Click the Reset View button again.
   2. Enter y(t) = sin (3.2t).
   3. Leave all other entries the same.
   4. Click Move and watch!
   5. Move your fish around the environment so you can see the trail.

   

   
   
   1. By increasing the range you can make the figure much more complex.
   1. Click the Reset View button again.
   2. Enter t = 0 to 30.
   3. Leave all other entries the same.
   4. Click Move and watch!
   5. Move your fish around the environment so you can see the trail.

   

   
   
   1. By changing the equation to cylindrical you can make it look like wings.
   1. Don’t use the Reset View button this time.
   2. Move around in the world to a position looking down on the weave.
   3. Click on the weaved square - the trail you just made. It should change colors rapidly - that is how you know it is selected.
   4. Choose Cylindrical.
   5. Leave all other entries the same.
   6. Click CHANGE and watch!

   
   
   
   

   Try using the Environment Menu options to edit trails, schooling fish, and several other aspects of the environment.
