Interface Marker

All Known Implementing Classes:

BasicMarker, ExtrudedPolygonEditor.ControlPointMarker, MarkersOrder.AppFrame.TimedMarker, RigidShapeEditor.ControlPointMarker, SurfaceImageEditor.ControlPointMarker

public interface Marker

A visual marker with position and orientation. The marker can be oriented in 3D space with a heading, pitch, and roll. However, not all implementations apply the orientation to the rendered marker. An implementation may apply any or none or the orientation parameters. For example, an implementation that renders the marker as a cone may ignore roll, because the cone is symmetric along its axis.

Method Detail

getAttributes

MarkerAttributes getAttributes()

getHeading

Angle getHeading()

Indicates heading of this marker. Not all implementations support heading. If the implementation does not support heading, the heading will be ignored.

Returns:

The marker heading in degrees clockwise from North. May be null, in which case no heading is applied.

getPitch

Angle getPitch()

Indicates pitch this marker. Not all implementations support pitch. If the implementation does not support pitch, the pitch will be ignored.

Returns:

The marker pitch in degrees from a surface normal. May be null, in which case no heading is applied.

getPosition

Position getPosition()

getRoll

Angle getRoll()

Indicates the roll of this marker. Not all implementations support roll. If the implementation does not support roll, the roll will be ignored.

Returns:

The marker roll in degrees clockwise. May be null, in which case no roll is applied.

render

void render(DrawContext dc,
            Vec4 point,
            double radius)

render

void render(DrawContext dc,
            Vec4 point,
            double radius,
            boolean isRelative)

setAttributes

void setAttributes(MarkerAttributes attributes)

setHeading

void setHeading(Angle heading)

Specifies the heading of this marker.

Parameters:

heading - the marker heading in degrees clockwise from North. May be null, in which case no heading is applied.

setPitch

void setPitch(Angle pitch)

Specifies the pitch of this marker. Not all implementations support pitch. If the implementation does not support pitch, the pitch will be ignored.

Parameters:

pitch - the marker pitch in degrees from a surface normal. Positive values result in a rotation toward the marker heading, or toward North if there is no heading. May be null, in which case no pitch is applied.

setPosition

void setPosition(Position position)

setRoll

void setRoll(Angle roll)

Specifies the roll of this marker. Not all implementations support roll. If the implementation does not support roll, the roll will be ignored.

Parameters:

roll - the marker roll in degrees clockwise. May be null, in which case no roll is applied.
