Detailed Description

p_curve: a parametric curve to plot

This class takes two functions that accept doubles and return a double. It then samples t in [0,1] and connects the dots with straight lines

Constructor & Destructor Documentation

glot::p_curve::p_curve	(	const function &	x_f,
		const function &	y_f,
		const color &	col,
		double	t0 = 0,
		double	tf = 1
	)			[inline]

Constructor.

Parameters:

	x_f	- the parametric definition of x
	y_f	- the parametric definition of y
	col	- the color of the curve
	t0	- the beginning of the parameterization
	tf	- the end of the parameterization

glot::p_curve::p_curve	(	function::double_function	x_f,
		function::double_function	y_f,
		const color &	col,
		double	t0 = 0,
		double	tf = 1
	)			[inline]

Constructor.

Parameters:

	x_f	- the parametric definition of x
	y_f	- the parametric definition of y
	col	- the color of the curve
	t0	- the beginning of the parameterization
	tf	- the end of the parameterization

Instead of declaring functions and a curve, we anticipate it being useful to just declare a curve with the functions you've already defined

Member Function Documentation

void glot::p_curve::dl_gen

(

const screen &

s

)

[virtual]

Display-list generator.

Parameters:

s

- the screen specs

The screen stores the dimensions of the plot, etc. and based on that information, this function generates the geometry for the primitive. Typically this might be stored in a display list, but that is up to the container class, grapher

Implements glot::primitive.
