Member Function Documentation

◆ getDistance2FromPoint()

float DriveNode3D::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 node.

Parameters
xyzThe point for which the distance to the line is computed.

Reimplemented from Quad.

◆ getDistances()

void DriveNode3D::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.

Parameters
xyzThe coordinates of the point.
resultThe X coordinate contains the sidewards distance, the Z coordinate the forward distance.

Implements DriveNode.

◆ is3DQuad()

virtual bool DriveNode3D::is3DQuad ( ) const
inlinevirtual

Returns true if this quad is 3D, which additional 3D testing is used in pointInside.

Reimplemented from Quad.

◆ pointInside()

virtual bool DriveNode3D::pointInside ( const Vec3 p,
bool  ignore_vertical = false 
) const
inlinevirtual

Returns true if a point is inside this quad.

Reimplemented from Quad.
