Typedef Documentation

VecType

template<typename T, index_t N>

using VecType = typename PointType<T,N>::point_t

The type of a vector in N dimensions with elements of type T.

VecType<T,N> is a Vec<T,N> in dimension > 1, otherwise a T.

Function Documentation

from_rgb()

template<typename T>

Vec< T, 3 > from_rgb

(

int

aRGB

)

Parameters

aRGB	A packed 8-bit per channel RGB color value (with alpha or irrelevant data in the eight high order bits).

Returns

An (r,g,b) tuple extracted from aRGB.

permutation_apply()

template<typename RandomAccessIterator>

void permutation_apply	(	index_t *	p,
		index_t	n,
		RandomAccessIterator	v )

Apply a permutation in-place, resetting the permutation to identity in the process.

Parameters

p	An array of n indecies representing the sources of elements in the permuted sequence; i.e. output[i] = input[p[i]]. p will contain the identity permutation after the function returns.
n	The number of elements in the permutation. @v A random access iterator containing the sequence to be permuted.

permutation_sign()

index_t permutation_sign ( index_t * p, index_t n )

inline

Compute the sign of a permutation, resetting the permutation to identity in the process.

Parameters

p	An array of n indecies representing the permutation mapping. p will contain the identity permutation after the function returns.
n	The number of elements in the permutation.

rainbow()

template<typename T>

Vec< T, 3 > rainbow

(

double

s

)

An (r,g,b) color tuple representing a hue selected by s, with 0 being red, progressing in rainbow order through the colors before returning to red at 1. The cycle is extended similarly outside of (0, 1).

Parameters

s	Rainbow parameter between 0 and 1.

Returns

An (r,g,b) color tuple.

triangle_normal()

template<typename T>

Vec< T, 3 > triangle_normal	(	const Vec< T, 3 >	p1,
		const Vec< T, 3 >	p2,
		const Vec< T, 3 >	p3 )

Returns

The normal of the triangle formed by p1, p2, and p3.
