CS 1025 01 - Week #5 (Sep 22-26)


Monday, September 22nd


  1. NetLogo turtle graphics and x-y position indicator fun.

  2. Modeling a MUSHROOM HUNT in NetLOGO.

  3. The SHODOR Data Flyer tool.

  4. Finding the slope of a line: Rise over the Run. It is wise to remember the rise is the y's. The runner looks like an x, perhaps.

  5. Adobe Flash Bouncing Ball for comparing Ease In and Ease Out and no easing...

  1. Gravity and Flash: Modeling the effect of gravity.

  2. Getting the ball to bounce. physicsBounce.txt...

  3. The Flash application: GravityWithBounce.fla to look at and use if needed.

  4. Microsoft Excel slope for Classic Tween without Ease In and with Ease In.

    Without Easing and With Ease In data for the Data Flyer tool.
    Animation with No Ease In... Animated to Ease In at 100% Flash custom setting...

  5. Plot this set of numbers (from Maya 3D Graphics planet orbit animation).

    Here is the absolutely best fitting linear equation y = mx + b, for the
    above data.  The slope of the straight line is m and the intercept is b.
    
                 When x is equal to 0, the equation becomes y = m*0 + b, or
                                                            y = 0 + b = b.
    
      y = f(x) = 3.104 * x - 6.090  or  y = 3.1 * x - 6.1
    
    The best CURVE fitting quadratic equation for the above set of 
    8 points, i.e. (x, y) pairs is:
    
        f(x)  =  y = 0.416 * x*x  -  0.641 * x  +  0.152
         
                              2
           or    y  =  0.416 x   -  0.641 x  +  0.152
