Detailed Description

Power ellipse section.

Power ellipse is equivalent to an ellipse where the y coordinate has a power applied to it before scaling to given height. With a power lower than 1 the section resembles a rectangle with rounded edges, with a greater than 1 the section resembles a lenticular section. When power = 1 the section is an ellipse The X offset moves the maximum height to the given offset from the centre

◆ GetPoint()

XY CSectionPowerEllipse::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.
