Original sentence: "Bending" of objects cannot be done without resorting to exotic techniques, such as tesselation.- International Raytracing Competition, where POV-Ray artists have submitted many outstanding images.A Turing-complete C-like scene description language that supports macros and loops.According to the documentation for the Windows version:.From our website alone we see well over 100,000 downloads per year, and this of course doesn't count the copies that are obtained from our mirror sites, other internet sites, on CD-ROM, or from persons sharing their copies.Functions that, among other things, can be used for generating new patterns for isosurfaces, for parametric surfaces etc.Isosurfaces, which directly render surfaces defined by a mathematical function.It is possible to easily convert files from other 3D formats for use in POV-Ray, but conversion in the other direction is almost impossible.Objects that can be described in terms of spheres, boxes, and tori, etc.POV-Ray internally represents objects by their mathematical definitions instead of as triangles or other simple primitives, like most renders.POV-Ray, in addition to ordinary shapes like tori, spheres and heightfields supports exotic mathematically defined primitives such as the isosurface (a finite approximation of an arbitrary function), the polynomial primitive (an infinite object defined by a 7th order or lower polynomial), the julia fractal (a 3-dimensional slice of a 4-dimensional fractal), the superquadratic elipsoid (a cross between a sphere and a square), and the parametric primitive (using equations that represent its surface, rather than its interior).Some features, like radiosity and splines are still in development and may be subject to syntactical change.This has several effects:.Without a doubt, POV-Ray is the world's most popular raytracer.are perfectly smooth and accurate
