GEAR3D GUI example of 3D gear.
GEAR3D will pop up a GUI example of 3D gear. The gear rolls on a geared ground based on the mouse location. It uses the x-location of the mouse pointer for the gear location. Use the arrow keys to change the view. Press SPACEBAR to reset the view. This was inspired by Mike Agostini's 3D Clock submission in FEX:
The gear is made of 2 surface objects, and the ground is a single surface object. Since the moving part (gear) only contains 2 objects, the animation update is quite smooth. It uses OpenGL rendering.
GEAR3D accepts 3 optional arguments that specify the number of teeth on the gear, number of spokes, and the gear ratio between the ground and the gear.
GEAR3D('teeth', 30) - default is 50.
GEAR3D('spokes', 4) - default is 8.
GEAR3D('ratio', 2) - default is 3. This also determines how big the ground radius is.
Only positive integers are allowed.
This was created in R13SP1, so nested function is not utilized. Nested function will improve how surface data are passed between functions.
