s

a Sphere

Returns

the type of intersection

t_out

Checks whether the given Ray self intersects the given Box b.

See also: intersect_box()

b

a Box

Returns

true if the ray intersects the box

source

pub fn intersects_sphere(&self, s: &Sphere) -> bool

Checks if the given Ray self intersects the given Sphere s.

See also: intersect_sphere()

source

pub fn intersects_triangle(&self, t: &Triangle) -> bool

Checks whether the given Ray self intersects the given Triangle b.

origin

the origin of the ray

direction

the direction vector

Returns

the initialized ray

source

pub fn from_vec3(origin: Option<&Vec3>, direction: Option<&Vec3>) -> Self
