Ray Tracing of Geometric Primitives According to the RenderMan-Standard
Ray Tracing of high-quality images has two basic requirements: a renderer and a modeler. Usually , communication between those two is done by a speciied le-format. Each renderer capable of that format should produce images according to the speciication. One popular and powerful format is the RenderMan Interface Bytestream Protocol by Pixar. Unfortunately, its speciication is ambiguous in some c...
متن کاملHuygens wavefront tracing: A robust alternative to conventional ray tracing
We present a method of ray tracing that is based on a system of differential equations equivalent to the eikonal equation, but formulated in the ray coordinate system. We use a first-order discretization scheme that is interpreted very simply in terms of the Huygens’ principle. The method has proved to be a robust alternative to conventional ray tracing, while being faster and having a better a...
متن کاملA contact-tracing procedure.
The increase in the number of new cases of gonorrhoea and the apparent expansion of the reservoir of carriers of the disease have directed attention to the need for reviewing contact-tracing techniques. To obtain the opinions of others on this subject, a *questionnaire was sent to the physicians-in-charge of 205 special treatment centres in England in April 1962. From the replies received, it w...
متن کاملA Semantics for Tracing
We define a small step operational semantics for a core of Haskell. We modify this semantics to generate traces, specifically Augmented Redex Trails. This small and direct definition of Augmented Redex Trails shall improve our understanding of them and shall help to extend them systematically. 1 Hat — The Haskell Tracer Hat is a tool for viewing the computation of a Haskell program in various w...
متن کاملTracing a single user
Let g(n, r) be the maximum possible cardinality of a family F of subsets of {1, 2, . . . , n} so that given a union of at most r members of F , one can identify at least one of these members. The study of this function is motivated by questions in molecular biology. We show that g(n, r) = 2 n r , thus solving a problem of Csűrös and Ruszinkó.
