Detailed Description

This class draws markers at trajectory points.

The MarkerArtist is a type of TrajectoryArtist that draws markers at points of a trajectory. Markers can be standard OpenGL points or point sprites that use a specified image. Markers can be drawn at the beginning or end of a Trajectory, or at specified intermediate points.

Member Enumeration Documentation

DrawnMarkers

enum OpenFrames::MarkerArtist::DrawnMarkers

Indicates which data points should be drawn as markers.

IntermediateType

enum OpenFrames::MarkerArtist::IntermediateType

Indicates how intermediate marker spacing is determined.
