Photography has always inspired me, especially shots of nature and wildlife from the National Geographic magazines. I decided to use the American alligator as the subject for my project, perhaps because I’ve always been fascinated by reptiles (this species in particular has truly brilliant colors) and I really wanted to enjoy the modeling process.
Up until this point, every line of code we've shown you has done a simple task, such as performing an arithmetic operation, or checking a boolean condition, or assigning to a variable. Functions allow you to do a whole lot in one line of code. Instead of performing a simple task, a single line of code can display a menu of choices, or compute complicated three-dimensional transformations, or even...
Before reading the following article, please note: This "article" is a JOKE and has absolutely nothing to do with the real Linux XP distro. I have never used Linux XP myself and have absolutely no idea what that distro is like. I wrote this joke article many years ago, when there was no Linux distro called "Linux XP." Therefore, this article has nothing to do with that distro....
Take warnings to heart: Use your compiler's highest warning level. Require clean (warning-free) builds. Understand all warnings. Eliminate warnings by changing your code, not by reducing the warning level.
In this tutorial you will create a small application which does nothing useful, but illustrates one way the application can get input from the outside world. (Stephanie.) In a "real" application, of course, that input would cause meaningful changes in the application's behavior. In the illustrative application, the input is used merely to cause a change in the color of a rectangle on the...
So, you want to learn the Python programming language but can't find a concise and yet full-featured tutorial. This tutorial will attempt to teach you Python in 10 minutes. It's probably not so much a tutorial as it is a cross between a tutorial and a cheatsheet, so it will just show you some basic concepts to start you off. Obviously, if you want to really learn a language you need to program in...
How to use the Linux command line as a file manager. Learn how to copy, move, and delete files under Linux with the cp, mv, and rm commands.
he first step is very simple. AddressBook has an array which contains all our contacts. We will not use attr_accessor because we don't want the user to access this array directly. We will write our own access methods.
Sets are ok, arrays are great. Suppose we want to create three one-dimensional arrays for 50 members in our programming community. The first array is for names, the second for e-mails, and the third for number of uploads (components or applications) to our community. Each array (list) would have matching indexes and plenty of code to maintain all three lists in parallel. Of course, we could try...
THE ABILITY OF A COMPUTER TO PERFORM complex tasks is built on just a few ways of combining simple commands into control structures. In Java, there are just six such structures -- and, in fact, just three of them would be enough to write programs to perform any task. The six control structures are: the block, the while loop, the do..while loop, the for loop, the if statement, and the switch...
Pascal's semicolon is a bit like English's period (full stop). Because so many lines in Pascal end with a semicolon, and because putting one before an "else" causes problems, and because if...then...else statements are usually split across two (or more) lines, I still enter similar lines in my programs as follows:
This tutorial is the first in a series of "would-be" tutorials about graphical programming in the X window environment. By itself, it is useless. A real X programmer usually uses a much higher level of abstraction, such as using Motif (or its free version, lesstiff), GTK, QT and similar libraries. However, we need to start somewhere. More than this, knowing how things work down below is...
With just a circle, a few ovals and the Inner Glow effect, you can create a quick and very useful glass bowl image in Illustrator.And once you master this technique, it can be easily adapted for many different uses.
Before you can access files on a floppy, CDROM, zip drive, or any other device (including your hard drive), you need to tell Linux where in the directory tree you would like those files to appear. This process is called mounting the file system. Please note that you do not mount a device, you mount a file system that resides on the device. Also note that when you are done using it you should...
SMS (also known as text-messaging) has grown into a very popular method of communication. It has been around in Europe and Asia since the early nineties and its use is steadily increasing in the US as well. SMS stands for "Short Message Service" and uses mobile phones to transmit (surprise, surprise) short messages to and from mobile phones and whilst many of us might not know this, it...
