[osg-users] Obj model visualization using osg

[Christian Buchner]

What you are describing is a highly specialized application, not a generic
3D model viewer.

This application also has a lot of requirements concerning the 3D model
itself. All parts must be explicitly modeled. Most 3D models of cars do not
fulfill this requirement as these would simply consist of a single mesh for
the car's body to speed up rendering. Hidden parts (like the engine) are
not modeled for rendering performance reasons and often back faces of said
mesh are culled.

Furthermore the logic to decide in which order to explode the parts, and in
what direction they need to move in order to not intersect with other parts
is quite complex. It's probably best if this is done manually for each 3D
model.

As one example for such an exploded view of a model, the Steam VR Lab demo
"Robot Repair" comes into my mind. It's fun to look at, as parts are moving
and rotating in exploded view.
