Detailed Description

template<size_t N>
struct lagrange::raycasting::HitBaseN< N >

Shared base struct for multi-ray and multi-point hits.

Template Parameters

N	Number of rays/points in the packet (e.g., 4, 8, or 16).

Member Data Documentation

mesh_indices

template<size_t N>

Eigen::Vector<uint32_t, N> mesh_indices

Initial value:

=
        Eigen::Vector<uint32_t, N>::Constant(invalid<uint32_t>())

Index of the mesh that was hit.

instance_indices

template<size_t N>

Eigen::Vector<uint32_t, N> instance_indices

Initial value:

=
        Eigen::Vector<uint32_t, N>::Constant(invalid<uint32_t>())

Index of the instance that was hit (relative to the source mesh).

facet_indices

template<size_t N>

Eigen::Vector<uint32_t, N> facet_indices

Initial value:

=
        Eigen::Vector<uint32_t, N>::Constant(invalid<uint32_t>())

Index of the facet that was hit.

barycentric_coords

template<size_t N>

Eigen::Matrix<float, 2, N> barycentric_coords = Eigen::Matrix<float, 2, N>::Zero()

Barycentric coordinates of the hit points within the hit facets.

Given a triangle (p1, p2, p3), the barycentric coordinates (u, v) are such that the surface point is represented by p = (1 - u - v) * p1 + u * p2 + v * p3.
