Detailed Description

This class is used for debugging.

It allows to show an arbitrary curve in the race. The curve is shown as a 'tunnel', i.e. in the constructor you can specify the width and height of this tunnel. Each point then adds 4 vertices: point + (+- width/2, +- height2, 0). That's not exact (if the curve is not parallel to the z axis), but good enough for debugging.

Constructor & Destructor Documentation

ShowCurve()

ShowCurve::ShowCurve	(	float	width,
		float	height,
		const irr::video::SColor &	color = irr::video::SColor(77, 0, 179, 0)
	)

ShowCurve constructor.

It just creates an empty dynamic draw call.

Member Function Documentation

addPoint()

void ShowCurve::addPoint

(

const Vec3 &

pnt

)

Adds a point to the curve ('tunnel').

This adds 4 vertices, and it creates the triangles to connect it to the previous point.

Parameters

pnt	The new point to add.

makeCircle()

void ShowCurve::makeCircle	(	const Vec3 &	center,
		float	radius
	)

Makes this curve to show a circle with given center point and radius.

Parameters

center	Center point of the circle.
radius	Radius of the circle.

setHeading()

void ShowCurve::setHeading

(

float

heading

)

Sets the heading for the curve.

Parameters

heading

The heading (in rad).
