Detailed Description

An infinite cone.

Constructor & Destructor Documentation

Cone() [1/2]

G3D::Cone::Cone	(	const Vector3 &	tip,
		const Vector3 &	direction,
		float	angle
	)

Parameters

angle

Angle from the center line to the edge, in radians

Cone() [2/2]

G3D::Cone::Cone	(	const Vector3 &	tip,
		const class Box &	box
	)

Forms the smallest cone that contains the box.

Undefined if the tip is inside or on the box.

Member Function Documentation

contains()

bool G3D::Cone::contains

(

const class Vector3 &

v

)

const

True if v is a point inside the cone.

halfAngleFromSolidAngle() [1/2]

static float G3D::Cone::halfAngleFromSolidAngle ( float  solidAngle )

static

Returns the half-angle (in radians) of a cone that subtends solidAngle (in steradians)

halfAngleFromSolidAngle() [2/2]

static double G3D::Cone::halfAngleFromSolidAngle ( double  solidAngle )

static

intersects()

bool G3D::Cone::intersects

(

const class Sphere &

s

)

const

Returns true if the cone touches, intersects, or contains b.

If c.intersects(s) and c.intersects(Sphere(s.center, s.radius * 2) then the sphere s is entirely within cone c.

randomDirectionInCone()

Vector3 G3D::Cone::randomDirectionInCone

(

Random &

rng

)

const

solidAngleFromHalfAngle() [1/2]

static float G3D::Cone::solidAngleFromHalfAngle ( float  halfAngle )

static

Returns the solid angle (in steradians) subtended by a cone with half-angle halfAngle.

solidAngleFromHalfAngle() [2/2]

static double G3D::Cone::solidAngleFromHalfAngle ( double  halfAngle )
