It is also useful to set only one of the rotation angles to a non-zero value and watch the rotation around a line parallel to that axis take place.

Figure 4 shows a screen shot of the disk in motion somewhere between the beginning and the end of its very complex trajectory forone particular set of rotation and anchor point parameters.

Exercises

I will also provide exercises for you to complete on your own at the end of the module. The exercises will concentrate on the material that you have learnedin this and previous modules.

## The game-math library named GM01

The game-math library named GM01 has not been modified since I presented and explained it in an earlier module titled GAME 2302-0135: Venturing into a 3D World . A copy of the source code for the library is provided in Listing 30 for your convenience. Since Ihave explained the code in the library in earlier modules, I won't repeat those explanations here.

A link to a zip file containing documentation for the library was provided in the earlier module.

## The game program named GM01test08

This is an interactive 3D game program. In fact, this is the first game program that I have presented in this collection on game math. This gamesimulates a school of prey fish being attacked and eaten by a predator. The objective for the player is to cause the predator to eat all of the prey fish ina minimum amount of time. Although the story line of the game is rather simple, the math involved is not simple at all.

Player initiates attacks

The player in this game initiates a series of attacks by the predator by clicking the Attack button shown in Figure 5 . The winning strategy for the player is to time the attacks in such a way as to minimize the elapsed timerequired for the predator to eat all of the prey fish. The final elapsed time depends on both strategy and chance. In other words, as is the case in manygames, this game is part strategy and part chance.

A swirling cluster of prey fish

The prey fish, (shown in red) , tend to swim in a large swirling cluster as shown in Figure 5 when they aren't being harassed by the predator.

Figure 5 Prey fish in a large swirling cluster.

Predator behavior

The predator, (shown in blue in Figure 5 ) , swims around the cluster, darting into and through the cluster when the user clicks the Attack button. During an attack, the predator attempts to eat as many prey fish aspossible. When the predator attacks, the prey fish tend to scatter (as shown in Figure 1 ) , breaking up their tight formation and making it more difficult for the predator to catch them. If the predator is allowed to swim around themagain for a short period following an attack, they will form back into a cluster.

Proper timing is important

The attacks should be timed so that the prey fish are in a reasonably tight cluster at the beginning of each attack so that multiple prey fish will be eatenduring the attack. However, allowing too much time between attacks is detrimental because it increases the total elapsed time. Thus, the player mustmake a tradeoff between elapsed time between attacks and the tightness of the cluster at the beginning of each attack. Another disadvantage of waiting too long between attacks will be explained later.

where we get a research paper on Nano chemistry....?
what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level

I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think

Nasa has use it in the 60's, copper as water purification in the moon travel.

what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
