A survey of implicit surface rendering methods, and a proposal for a common sampling framework
We consider several applications of implicit surfaces in visualization, and methods for rendering them. In particular we focus on geometry processing techniques for mesh extraction; and ray casting methods for direct rendering of implicits. Given that both methods rely on sampling the implicit function in question, we design a software framework that could accomodate both algorithms. We conclude by evaluating the time complexity and performance of existing systems, and discuss the long-term potential of both methods for rendering and computational goals.
