QuickDraw(TM) 3D Version 1.5.3 was released on September 4, 1997. This software requires a Pentium or Pentium Pro based computer with a minimum of 16 megabytes of memory (RAM), Windows 95 or Windows NT (3.51 or 4.0), and a video board providing 256 colors (8-bit) at 640x480 resolution. High Color (16-bit) or True Color (24-bit or 32-bit) video highly recommended.

Description:

QuickDraw 3D enables your computer to display three-dimensional graphics using applications designed to take advantage of QuickDraw 3D. It also provides a common file format, called QuickDraw 3D Metafile (or 3DMF for short), for exchanging 3D documents. QuickDraw 3D also provides acceleration services which support plug-and-play accelerator cards. Version 1.5.3 contains miscellaneous bug fixes and optimizations.

This software consists of a .ZIP archive of QuickDraw 3D for Windows. To use, download it to your hard drive and then "unzip" to decompress the software.

Using QuickDraw 3D

The QuickDraw 3D folder includes the following applications, 3D models, and textures that allow you to explore the 3D capabilities of your computer:


• SimpleText version 1.4 and Scrapbook version 7.5.2. These applications allow you to open and interact with 3DMF models.
• A new Scrapbook File with sample 3DMF models.
• A number of 3DMF models provided by Model Masters
( www.viewpoint.com ), and Zygote ( www.zygote.com ).

If you are using a localized system, and you install this U.S. software, you will need to copy the Scrapbook File in the QuickDraw 3D Folder to the System Folder on your computer. Otherwise, when you choose Scrapbook from the Apple menu, you will get an empty scrapbook. Note that this operation will replace any existing Scrapbook File in the System Folder, thus erasing any previously stored contents.
