Lesson1- The Bouncing Ball

Here, you will start your journey through the wonderful world of computer animation.
1). Open a new 3D file in your keyframing capable
software, for example, we used Microstation.
2). Create a ground surface for the sphere to bounce on.
3). Create a sphere
4). Apply materials to sphere and slab - You can use a
home page background, or something that is symmetrical.
5). Put in a light source. This creates a shadow and realistic
appearance, but is not necessary.
6). Open your animation palette, also put in a background if desired.
7). Define actors under animation, this is what moves
(the ball in this case).
8). Open key framing under animation.
9). Select a start location for the ball, in the air,
above the platform is preferable.
10). Now save that position as start under keyframing
. *Give the keyframe positions names that will hint
the posititon of the ball.
11). When the ball hits the surface, it changes shape.
To modify your actor (ball), select manipulate
actor under your animation palette.
12). Now scale the ball, to make it appear squished.
Since it is bouncing on the ground, use stretch z-axis.
13). Move the ball near the surface of the ground,
so that it appears to touch the ground. Save
this as a key frame.
14). Now use stretch z-axis to stretch the ball and
move it back to its original location. Save this
as a keyframe.
15). Now you will use the script command to
set the speeds of the keyframes and the
frames between each keyframe.
16). Now use your movie recording
command to record the sequence as a movie.
