SDF Renderer

Interactive rendering framework for distance function representations. Sphere tracing, introduced by {it J. C. Hart.} [Sphere tracing: A geometric method for the antialiased ray tracing of implicit surfaces. The Visual Computer, 12, 527--545 (1994)], is an efficient method to find raysurface intersections, provided the surface is represented by a signed distance function (SDF) or a lower estimate of it.par This paper presents an interactive rendering framework for visualising exact and estimate SDF representations. We demonstrate the performance of the system by visualising 3D fractals and its modularity by rendering algebraic and meta surfaces. In addition, we discuss SDF estimation of algebraic surfaces.
