Bouncing Ball Tutorial Pt. 2

So the new assignment was to recreate the bouncing ball tutorial and change some things, or add some things, and play with the system. I did just that, by adding some ball rotation and and some other extras.

That is a rendered screen from the animation, with lights and shadows added. I have two spotlights in place from two exact opposite views that cross on the hoop. For things that you can't actually see from a still, the green/red fire is a normal fire effect. Also, the ball has a cat face that says "meow" under it.

The hoop is rotating 90 degrees every ten seconds, and is placed so that the ball still goes through it without touching the hoop. Also, the ball rotates forward 90 degrees every few seconds at a rate that looks natural. At the end of the animation, the ball hits the wall and begins spinning back the other way, rolling towards the hoop, with the correct direction of spin. Also not seen in this shot is the ramp that the ball starts on. Instead of simply a bouncing character like the original tutorial gives, this is a normal ball that rolls off of a ramp into the scene. The whole scene can be seen here:




The first screen shot is without the effect of lighting, so the whole setup is visible, while the second shows the scene with the lighting effects.

Bouncing Ball Tutorial

So the first assignment we had to do was make a bouncing ball that went through a static hoop. Since we did it in class, the tutorial was pretty easy. Making the ball and such was simple enough, and the animation using keyframes is a relatively easy concept to grasp once you have a handle on the idea.

After I was done, I decided to continue playing with the program, and added a few more things. To start, rather than have the ball begin on the ground, I added a ramp that it roles off of, onto the floor to begin the bounce. Then, I gave the hoop keyframes to rotate around. Then, to keep a bit of realism, the bouncing of the ball fades into a roll. I also added a wall at the end that the ball runs into and bounces back the other way.

Around this point, the lack of rotation of the ball bugged me, so I added in keyframes to make the ball rotate. I made sure to make the ball rotate back the other way once it ran into the wall. The rotation, however, screwed up the deformer, so I took it out. Here are some screen shots from different angles of the finished product.
