const ray3 &  ray,
const hermes::vec3 &  inv_dir,
const i32  dir_is_neg[3],
real_t  max_t = Constants::real_infinity 
)
static
Parameters
bounds
ray
inv_dir
dir_is_neg
max_t
Returns

◆ intersect() [2/5]

Result< real_t > hermes::GeometricPredicates::intersect ( const hermes::bbox3 &  bounds,
const ray3 &  ray,
real_t *  second_hit = nullptr 
)
static
Parameters
bounds
ray
second_hit
Returns

◆ intersect() [3/5]

Result< real_t > hermes::GeometricPredicates::intersect ( const hermes::Line2 &  line,
const ray2 &  ray 
)
static

Intersects a line by a ray.

Parameters
line
ray
Returns
the ray parametric coordinate of the intersection

◆ intersect() [4/5]

Result< real_t > hermes::GeometricPredicates::intersect ( const Plane &  plane,
const Ray3 &  ray 
)
static
Parameters
plane
ray
Returns

◆ intersect() [5/5]

Result< real_t > hermes::GeometricPredicates::intersect ( const point3 &  p1,
const point3 &  p2,
const point3 &  p3,
const Ray3 &  ray,
real_t *  b1 = nullptr,
real_t *  b2 = nullptr 
)
static

BBox / Ray3 intersection test. b1 and b2, if not null, receive the barycentric coordinates of the intersection point.

Parameters
p1[in] first triangle's vertex
p2[in] second triangle's vertex
p3[in] third triangle's vertex
ray[in]
tHit[out] intersection (parametric coordinate)
b1[out] barycentric coordinate
b2[out] barycentric coordinate return true if intersection exists
