Download and Render Time Most of the VRML files will take a while to download. In total, each world, including images, is approximately 200K. This would take about a minute to download on a 28.8 Kbps modem. Double the time for a 14.4 Kbps modem. In addition to this, it takes a lot of time to render and display the VRML world. Because of this, we suggest a Pentium with at least 16 megabytes of RAM. If you have a Macintosh, then we suggest a at least a Powermac. Some of the worlds take longer to render than others, so please be patient. The first world is the biggest and takes about five minutes to render. How can I tell if it is done rendering? If you are using Live3d, you will see the structure of the building displayed first. It is not done yet. You need to wait until you see ALL of the building's textures, such as stone or wood, before you start to move around. Also, we UNIX GNUzipped all of the VRML files, so unless you have created that as a helper, you will get an "Unrecognized encoding method: g-zip" when you try to download a VRML file. There is nothing abnormal about this, so just click yes, and all will be well. You computer will understand it, it has just not been told it always has your permession to.

Movement: If you are using Netscape Live3d, then you can move around using the mouse or arrow keys. Using the mouse, you can left click (click with a macintosh) on a point on the screen, hold the button down, and then move the mouse up, down, left, or right. Your view on the screen will change accordingly. Additionally, we have created what are called viewpoints. These are a set of predetermined views of the scene. You can acces these by pulling up the right click menu. To do this on a PC you can right click. Then select the viewpoints menu and then the viewpoint you want to look at. If you are using a Macintosh, click somewhere in the VRML world and hold your mouse button down WITHOUT moving it for about five seconds. The menu will pop up and you can then select the viewpoint. You can practice these techniques on the VRML file to the right. It is a red box that has several viewpoints. Have fun! Happy exploring!
