Stylized Caustics: Progressive Rendering of Animated Caustics
In recent years, much work was devoted to the design of light editing methods such as relighting and light path editing. So far, little work addressed the target-based manipulation and animation of caustics, for instance to a differently-shaped caustic, text or an image. The aim of this work is the animation of caustics by blending towards a given target irradiance distribution. This enables an...
متن کامل106: Caustics
As early as 1927, legislation in the United States governing the packaging of lyeand acidcontaining products mandated that warning labels be placed on these products. In response to the recognition that caustic exposures were more frequent in children, the Federal Hazardous Substances Act and Poison Prevention Packaging Act were passed in 1970; these acts mandated that all caustics with a conce...
متن کاملOn nonconvex caustics of convex billiards
Oliver Knill July 29, 1996 Abstract There are billiard tables of constant width, for which the billiard map has invariant curves in the phase space which belong to continuous but nowhere di erentiable caustics. We apply this to construct ruled surfaces which have a nowhere di erentiable lines of striction. We use it also to get Riemannian metrics on the sphere such that the caustic belonging at...
متن کاملInteractively Rendering Dynamic Caustics on GPU
In this paper, a new technique is presented for interactive rendering of caustics fully processed on GPU. Without any pre-computation required, the algorithm can directly render refractive caustics from complex deformable transparent objects onto an opaque receiver surface. By the technique we accurately trace the path of the photons and calculate the energy carried by the photons emitted from ...
متن کاملRendering Caustics on Non-Lambertian Surfaces
This paper presents a new technique for rendering caustics on non Lambertian surfaces The method is based on an extension of the photon map which removes previous restrictions limiting the usage to Lambertian surfaces We add information about the incoming direction to the photons and this allows us to combine the photon map with arbitrary re ectance functions Furthermore we introduce ba lancing...
