Constructor & Destructor Documentation

SphericalSector() [1/3]

template<typename T , index_t N>

SphericalSector ( )

inlineconstexpr

Construct a spherical sector at the origin with radius 1 and an opening half-angle of 45 degrees.

SphericalSector() [2/3]

template<typename T , index_t N>

SphericalSector ( const Sphere< T, N > & s, Vec< T, N > v, T cos_a )

inlineconstexpr

Construct a spherical sector with center at the origin, having radius r.

Parameters

r	Radius of spehre.

SphericalSector() [3/3]

template<typename T , index_t N>

SphericalSector ( const point_t & c, T r, Vec< T, N > v, T cos_a )

inlineconstexpr

r	Radius of spehre.

Member Function Documentation

clip()

Vec< T, N > clip ( Vec< T, N > p ) const

inlineinherited

Nearest point on the interior of the shape.

If p is on the interior of the shape, return p unaltered; otherwise orthogonally project p to the shape's surface.

intersect()

template<typename T , index_t N>

Rect< T, 1 > intersect ( const Ray< T, N > & ray ) const

inline

xxx todo Shape-ray intersection test.

intersects()

bool intersects ( const Convex< T, N, Shape > & other ) const

inlineinherited

Convex shape overlap test.

Returns

True if and only if this convex shape overlaps other; false otherwise.

normal()

template<typename T , index_t N>

point_t normal ( point_t p ) const

inline

xxx todo Outward-facing direction.

project()

template<typename T , index_t N>

point_t project ( point_t p ) const

inline

xxx todo

Return the point p orthogonally projected onto the surface of the shape.

sdf()

template<typename T , index_t N>

T sdf ( point_t p ) const

inline

xxx todo Signed distance function.
