Overview

Packaging is the final step in the creation of our Synthetic Environment. Packaging brings together all the components of your world (models, textures, sounds, scripts etc), compresses, optimises and copies the resulting files to a directory which can then be uploaded or integrated into a web page.

Packaging will fail if any resources (textures etc) are missing so these errors have to be corrected before packaging can be completed successfully.

Tutorial

Launch Cosmo Worlds and Open the file camera_hud.wrl
Select File Menu > Publish.
Enter a name and location for your package directory.
Click Next all the way through, leaving all settings at their default values.

When prompted click Finish.

The folder you specified should now exist containing all the files that comprise your world.

Notice how the VRML (.wrl) files are about five times smaller than the files we were developing with. This is because the Publishing Wizard compressed them with gzip. They still operate exactly as intended.

Our total filesize for the camera project came in at 266Kb comprising:

  • VRML 50Kb
  • Textures 138Kb
  • Sounds 77Kb

The main VRML file would download in roughly 7 seconds on a 56kbps modem with everything downloaded within 40 seconds.
To preview your work simply double click on the file camera_hud.wrl.
