  \class SoMotion3Event SoMotion3Event.h Inventor/events/SoMotion3Event.h
  \brief The SoMotion3Event class contains information about 3D movement
  events.
  \ingroup events

  Motion3 events are generated by devices capable of "3D motion", for
  instance spaceballs. Instances of this class contains information about
  these devices' translations and rotations in all 3 dimensions.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
