3D OBJECTS AND DIGITAL GOBOS
About 3D Models and Digital Gobos (Objects)
3D Model and Digital Gobo files are arranged into individual folders within the /Mbox/Models folder.
Lighting
All 3D models and digital gobos require some amount of lighting to be properly visible. If the object file is used without
turning on one of the Mbox lighting fixtures or without using Drawmode 1 (Light), then the object will appear on the
screen as a black silhouette.
Guidelines:
+ 3D models respond best to the spotlight fixtures. The resulting shadows help enhance the 3D nature of the model.
+ Digital gobos respond best to the ambient light fixture or to Drawmode 1.
Vertex Array Files (Compiling)
When displaying a 3D model or digital gobo file on the screen, that file is read from the hard-drive just like the 2D
content. But loading model and digital gobo files in their original format (.obj, .svg) and converting them to be used
within the Mbox environment can be a slow process. Instead, Mbox Designer generates a new version of these files in
the
Mbox/Models folder using a proprietary format. The resulting vertex array files have been optimized to allow for
shorter load times when the files are requested for display. The process of creating the vertex array files is called
"compiling."
