Click the Vrml 2.0 tab to display the VRML 2.0 Preferences panel of CosmoPackage. This panel is present only if you have Cosmo Worlds installed on your system. You can set preferences only before the discovery stage. If you need to change any preferences after discovery, you'll need to restart the packaging process.
The Floating Point Precision pulldown menu allows you to specify the maximum number of significant digits to be used for the decimal part of floating point values in VRML files. Decimal values are rounded to the specified number of digits. Since shorter files download more quickly, you want to specify the minimum floating point precision necessary to render your scene accurately.
The default is to write out all significant digits that are stored for each value.
By default, CosmoPackage adds a .wrl suffix to all VRML files that don't already have one. Note that Netscape does not recognize a file as VRML without the .wrl extension. To disable this feature, click the box to remove the check.
By default, VRML files are compressed using gzip before they are packaged. Compressed files download faster and use less disk space, so use of this feature is recommended. Most browsers automatically decompress files that have been compressed. To disable this feature, click the box to remove the check.
Check the Optimize Textures box if you want CosmoPackage to optimize textures automatically. When this feature is enabled, CosmoPackage performs the following optimizations:
If a texture node has routes connected to it, no optimizations are performed.
The Media Conversion panel allows you to specify the file format of your packaged images, movie textures, and audio clips. Since browsers are not required to support all possible formats, you'll want to convert your files to the formats required by the VRML 2.0 Specification. Note that this panel operates only on local files; remote URLs and trusted references are untouched. By default, no file conversion occurs.
In this panel, an asterisk next to the file format indicates that this format may not be supported by all browsers. The VRML 2.0 Specification requires support for PNG and JPEG image formats, MPEG1 movie texture format, MPEG1 audio clip format, and WAV audio format. Support for the GIF image format and MIDI file type 1 audio format is recommended but not required.
The utility used for image conversion is imgcopy. The utility used for converting movies and sounds is dmconvert. These utilities are not a standard part of your operating system. If they are not installed, an error message will appear on your screen. Obtain the utilities from the CD or Web site where you obtained Cosmo Worlds, if they are not already on your system.
