Member Function Documentation

virtual void Track::EditAssist::ControlPoint::draw

(

)

const [pure virtual]

Draw the control point for the editor.

May draw additional lines to show bounds or to indicate what it relates to.

Uses OpenGL commands. It expects the modelview matrix to translate points from world space. Point and line primitives may be drawn. After calling, the current OpenGL colour could be anything.

Implemented in Track::EditAssist::EdgeStrengthHandle, Track::EditAssist::LineConstrainedControlPoint, Track::EditAssist::RotationHandle, Track::EditAssist::SegmentConnectionHandle, Track::EditAssist::TrackAttachmentHandle, and Track::EditAssist::VertexRotationHandle.

const btVector3 & Track::EditAssist::ControlPoint::get_position

(

)

const

Get the posistion of the point.

The handle should be drawn here for is_here to match up.

Definition at line 38 of file ControlPoint.cpp.

bool Track::EditAssist::ControlPoint::is_here	(	btVector3	start,
		btVector3	stop,
		btScalar	radius
	)			const [virtual]

Check if the object lies along a given line segment.

Parameters:

	start	The start position of the line in world space.
	stop	The end position of the line in world space
	radius	to consider points near the line

Returns:

true if it is on or near the line, false otherwise.

Implements Track::EditAssist::Selectable.

void Track::EditAssist::ControlPoint::set_position

(

const btVector3 &

new_position

)

[virtual]
