Member Function Documentation

◆ getDistance2FromPoint()

float DriveNode2D::getDistance2FromPoint ( const Vec3 & xyz ) const

virtual

Returns the square of the distance between the given point and any point on the 'centre' line, i.e.

the finite line from the middle point of the lower end of the node to the middle point of the upper end of the node which belongs to this graph node. The value is computed in 2d only!

Parameters

xyz	The point for which the distance to the line is computed.

Reimplemented from Quad.

◆ getDistances()

void DriveNode2D::getDistances	(	const Vec3 &	xyz,
		Vec3 *	result
	)		const

virtual

Returns the distance a point has from this node in forward and sidewards direction, i.e.

how far forwards the point is from the beginning of the node, and how far to the side from the line connecting the center points is it. All these computations are done in 2D only.

Parameters

xyz	The coordinates of the point.
result	The X coordinate contains the sidewards distance, the Z coordinate the forward distance.

Implements DriveNode.

◆ m_line

core::line2df DriveNode2D::m_line

private

Line between lower and upper center, saves computation in getDistance() later.

The line is 2d only since otherwise taller karts would have a larger distance from the center. It also saves computation, and it is only needed to determine the distance from the center of the drivelines anyway.

◆ m_lower_center_2d

core::vector2df DriveNode2D::m_lower_center_2d

private

The center point of the lower two points (e.g.

points 0 and 1). This saves some computations in getDistances later. Only the start point is needed, and only in 2d.
