Detailed Description

Section made up of bezier curves.

Section defined as a series bezier curves, the class takes points as input. Four consecutive points describe a bezier curve, the fourth point of the current bezier curve and first point of the following bezier curve are shared. This ensures 0th order continuity of the section. Thus the number of points specified should be a multiple of 3, the number of bezier curves created is the number of points divided by 3.

Same as CreateSection except all the points will be spaced the same distance apart.

This should work fine as long as the first derivative of the parametric equation with respect to t is continuous and the number of points making up the section is not too small

◆ GetPoint()

XY CSectionBezier::GetPoint ( double t ) const

virtual

Get a point lying on the perimeter correspending to parametric value t.

Each section should be defined as a parametric function where t varies from 0 to 1 the function should start from the positive x axis at t=0 and go counter-clockwise through 360 degrees returning to its original position at t=1. In order for the CreateEquiSpacedSection function to work correctly, the parametric equation's first derivative with respect to t should be continuous.

Implements TexGen::CSection.

◆ GetPoints()

const vector< XY > & CSection::GetPoints	(	int	iNumPoints,
		bool	bEquiSpaced = `false`
	)		const

virtualinherited

Get a section with given number of points on the perimeter.

The section is created and saved to m_EdgePoints which is then returned. If this function is called multiple times with the same parameter the section need not be recreated. Note that the returned vector is only valid until the next call to this function, a copy of the vector should be made if it needs to be kept for any period of time.

Parameters

iNumPoints	Number of points the section is made up of
bEquiSpaced	If set to true, the code will attempt to space the nodes at equal distances apart
