Today we will talk about... How data visualization applies to physics. How animations can help physics. How we can make the animations and how we can put them on the web. Some HTML and the usefulness of JAVA Comparing Disney and me. Show some slides of what I can do.
How data visualization works Understanding of data through visualization Requires graphing and plotting software. 3D Graphs or contour plots.
How animations can help physics See physics moving in time Effects of time dependent functions Especially useful in three dimensions Many formats: gif, mpeg, and Quicktime
Making 3D images from scratch.
Some pictures of what we can do
How I make animations and how I put them on the web
Comparing Disney and Me Disney usually draws by hand. Disney puts it on a film frame. Disney puts it in a reel Disney projects it on the big screen. I draw by computer in ncgm format. I convert it into gif at this point. I animate it. I put it up on the web.
HTML The “programming language” for Internet Stands for Hyper-Text Markup Language Resembles a word processor assembly code Can be read by on any web browser
Example of HTML <HTML> <HEAD> <title><size, style>...text…<size, /style></title> <body bgcolor=“#hexdec” font, color, size> <p>…TEXT...<br> <img src =“./filename” options><br> <a href=“./link”>TEXT</a><br> <hr> …page info… </BODY> </HTML>
JAVA Made by Sun Microsystems Object oriented language Similar to Microsoft’s Visual Basic JAVA is OS independent Automatic compilation at user end.
JAVA also User dynamic language User controllability Can be linked to existing programs (even FORTAN) Home user can manipulate the initial conditions
Example of Java Program “Hello World” /** * Simple applicatin: HelloWorld.java */ public class HelloWorld { public static void main() { System.out.println("Hello, World!"); } };
