Function Documentation

template<typename T>

T geom::computeArea

(

const ads::FixedArray< 3, ads::FixedArray< 3, T > > &

p

)

Return the area of the triangle with points p[0], p[1] and p[2].

In 3-D the area is unsigned.

template<typename T>

T geom::computeArea	(	const ads::FixedArray< 3, T > &	a,
		const ads::FixedArray< 3, T > &	b,
		const ads::FixedArray< 3, T > &	c
	)

Return the area of the triangle with points a, b and c.

In 3-D the area is unsigned.

template<typename T>

T geom::computeArea

(

const ads::FixedArray< 3, ads::FixedArray< 2, T > > &

p

)

Return the area of the triangle with points p[0], p[1] and p[2].

In 2-D the area is signed.

template<typename T>

T geom::computeArea	(	const ads::FixedArray< 2, T > &	a,
		const ads::FixedArray< 2, T > &	b,
		const ads::FixedArray< 2, T > &	c
	)

Return the area of the triangle with points a, b and c.

In 2-D the area is signed.

template<int N, typename T>

T geom::computeContent	(	const ads::FixedArray< N, T > &	a,
		const ads::FixedArray< N, T > &	b,
		const ads::FixedArray< N, T > &	c
	)

Return the area of the triangle with points a, b and c.

In 2-D the area is signed. In N-D the area is unsigned for N > 2.

template<int N, typename T>

void geom::computeGradientOfContent	(	const ads::FixedArray< 3, ads::FixedArray< N, T > > &	p,
		ads::FixedArray< N, T > *	gradient
	)			[inline]

Calculate the gradient (with respect to a) of the area of the triangle with points p[0], p[1] and p[2].

This is simply a wrapper for computeGradientOfArea.

template<int N, typename T>

void geom::computeGradientOfContent	(	const ads::FixedArray< N, T > &	a,
		const ads::FixedArray< N, T > &	b,
		const ads::FixedArray< N, T > &	c,
		ads::FixedArray< N, T > *	gradient
	)			[inline]

Calculate the gradient (with respect to a) of the area of the triangle with points a, b and c.

This is simply a wrapper for computeGradientOfArea.
