Interactive Ray Tracing of 3D Indoor Scanned Point Clouds

We present an approach to render complex point cloud data using ray tracing, allowing us to render big 3D scanned scenes by proposing a framework that will allow realistic lighting effects. In particular, we address the main problem of robustly solving the ray-point intersection problem and suitable for high-quality recursive ray tracing. Our solution is based on intersecting the surface represented by points by defining so-called convex hull splat primitives, which support the effective use of common ray-tracing acceleration structures, limit the complexity of point intersection and interpolation operations, and can reduce point-splat artifacts near boundaries.
