Spur gear set

Finally, not perfect at all but working gear set in 3D. Thanks to asplech's blog about involute gear and this Spur Gear document, I finally get to know better about these cogged wheels.

It turned out that producing a set of involute gears requires quite a bit of geometry in addition to involutes.

Ripple test

This is my first water ripple experiment. I found a function on Youtube and had a quick experiment. The ripple effect is not perfect but could be a good start for whoever is interested to refine it.

Bouncing spring

Bouncing Spring

Bouncing is fun. A spring has potential (elastic?) energy that has many uses in our life. Can you think of any uses? I just had a front suspesion replace in my old car. There are two big springs (or perhaps 4, I did not check back wheels) on top of the two front wheels. The two springs make sitting in the car comfortable by obsorbing forces and only bouncing slightly when driving (on rocky road).

Analog clock

Analog clock

The TIMESENSOR of X3D is quite a complicated time mechanism to understand. As I have created some commands for easy animation, I thought that it would be interesting to test the TIMESENSOR with an analog clock.

Light with switch

Light with switch

After much thinking and planning, I have finally implemented an initial behaviour framework. Behaviour is different to animation. But it may also have effect of animation. In this blog, I have programmed a desk lamp -- a spotlight with a switch. You can click on the switch to switch on and off the light. When you do, you can also hear a switch sound, so have your speakers turned on to enjoy the virtual simulation of light, shadow and sound.
