Member Function Documentation

void GreatCircleArc::LineSegment::doGL	(	double	width,
		VisualizationState *	state,
		GreatCircleArc::LineSegment *	preceding = NULL,
		GreatCircleArc::LineSegment *	proceeding = NULL
	)		const

Draw a meshed line.

Parameters

width	the width of the line
state	The visualization state needed to obtain final 3D coordinates and the scale for the visualization
preceding	the line segment before this line segment, needed to calculate the right begining slope
proceeding	the line segment after this line segment, needed to calculate the right ending slope
