Detailed Description

Shared base struct for ray and closest point hits.

Member Data Documentation

barycentric_coord

Eigen::Vector2f barycentric_coord = Eigen::Vector2f::Zero()

Barycentric coordinates of the hit point within the hit facet.

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.
