WebRay tracing directly samples the implicit surface by computing the intersection point along a ray. In this paper, we focus on ray-tracing implicit surfaces using the Sphere Tracing algorithm proposed in [Har96]. This conceptually simple and general algorithm adaptively marches along the ray to ﬁnd the ﬁrst ray-object intersection. WebSphere tracing is a new technique for rendering implicit surfaces using geometric distance. Distance-based models are common in computer-aided geometric design and in the … can you play splatoon 2 offline
