Simple 3D graphics using Java

Isometric or Orthogonal 3D views In this article, I demonstrate 3D Graphics showing you how to project a surface in 3D using 3 modes for drawing the surface. There is a left-hand mode, a center mode, and a right-hand mode. This same transformation math works for 3D polyhedron objects as well and you could use if for voxel type games. I show some effects you can use on the surface such as zoom, pan, skew etc. This is entirely wire frame. I do not remove hidden lines. I do not fill or texture map. And I do not rotate. I may do all this in future versions of this article. 90-degree rotation is very easy to do. Using basic trigonometry math more fine rotation is not difficult. The Iso3D class I did not have to put this code in its own class. As a matter of fact, in such a simple demo applicati...

Database: H2 (formerly HypersonicSQL)

H2 Database and Java When I began using Java years ago I heard of a database that was being coded entirely using Java. This was HypersonicSQL and you can still download it at Sourceforge. The author working on it decided it needed a rewrite and he began H2 database. First download H2 installer at H2 download.  Get the stable version 1.4.195 as the h2 jar file for the last version .196 gave a class not found exception on startup looking for the driver. And the tutorial can be found here H2 Tutorial.  Next look at your install and find the H2/bin folder. Here you find the jar file needed h2-some-version.jar i.e. h2-1.4.195.jar. Most if not all databases now create the database when you connect to it. All we need to do is make the JDBC connection and create a table, add some records with SQL ...

Javascript Language

Javascript Javascript is not Java In the beginning, it was called Live Script. Its name was changed to Javascript or Microsoft JScript as a marketing ploy. The language is based on the EMCA script standard and specifications. Basically, Microsoft and Netscape invented Javascript. Javascript is similar in syntax to C or Java. Many Java concepts and standards are also part of Javascript. However, Javascript is not Java. Inline Javascript example. <html> <head> <title>JavaScript Hello World</title> <script> alert('Hello, World!); </script> </head> <body> Main body text goes here. </body> </html>   DHTML Now some years back there was this concept of DHTML.  DHTML was merely a combination of HTML, CSS, and Javascript along with th...

CSS: Cascading Style Sheets

CSS Explained What is CSS? It stands for Cascading Style Sheets. CSS is a style sheet language which is used to enhance or describe how a document written using a markup language is presented on a web browser. Basically, HTML or any other markup language should contain the content for the web page or view and CSS would do all the formatting and layout control. So all the fonts, positioning and decorating of all the elements on a web page is done using Cascading Style Sheets. Also, see HTML HyperText Markup Language,  w3.org Page body {     background-color: lightblue; } h1 {     color: white;     text-align: center; } p {     font-family: verdana;     font-size: 20px; } Even though CSS is used more commonly with markup languages such as HTML and XHTML, it can be used with XML documents as ...

HTML stands for HyperText Markup Language. In fact, it's the markup language which is used to create web pages and applications which you view every day on the internet. Its pretty much what began the internet as most people know it.
