class ads_t

Generic accelerating data structure (ADS) interface.

Subclassed by wt::ads::bvh8w_t

Public Functions

ads_t() noexcept = default
inline ads_t(std::vector<tri_t> tris) noexcept
ads_t(ads_t&&) = default
virtual ~ads_t() noexcept = default
inline const tri_t &tri(tuid_t tuid) const noexcept
inline const edge_t &edge(std::uint32_t euid) const noexcept
inline auto triangles_count() const noexcept

virtual const aabb_t &V() const noexcept = 0
virtual intersection_record_t intersect(const ball_t &ball, const intersect_opts_t &opts = intersect_opts_t::defaults()) const noexcept = 0

Intersects the ADS with ball, returning the intersection record and contained primitives.

virtual intersection_record_t intersect(const ray_t &ray, const pqrange_t<> range = {0 * u::m, limits<length_t>::infinity()}) const noexcept = 0

Intersects the ADS with a ray, returning the intersection record with the intersected primitive.

Parameters:

  • range – traversal bounds

  • z_search_range_scale – scaler for z-axis search range

virtual intersection_record_t intersect(const elliptic_cone_t &cone, const pqrange_t<> range = {0 * u::m, limits<length_t>::infinity()}, const intersect_opts_t &opts = intersect_opts_t::defaults()) const noexcept = 0

Intersects the ADS with an elliptic cone, returning the intersection record and contained primitives. Once the closest intersection is found, looks for triangles within a z distance from the closest point. This distance is computed as the cone major axis length time ‘z_search_range_scale’.

Parameters:

  • range – traversal bounds

  • z_search_range_scale – scaler for z-axis search range

virtual bool shadow(const ray_t &ray, const pqrange_t<> range) const noexcept = 0

Intersects the ADS with a ray. Returns TRUE if a hit was found.

Parameters:

range – traversal bounds

virtual bool shadow(const elliptic_cone_t &cone, const pqrange_t<> range) const noexcept = 0

Intersects the ADS with an elliptical cone. Returns TRUE if a hit was found.

Parameters:

range – traversal bounds

virtual scene::element::info_t description() const = 0
