Ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images. This allows computers to accurately render things like shadows, reflections, highlights, and bounced light. The result is a scene that looks more realistic with ...
We present a method for using ray tracing to render spline surfacesone that is suitable for any object generated from control vertices via tensor-product B-splines. The method derives from kajiya's work on ray tracing procedurally defined surfaces1 and makes use of two preprocessing steps. One ...

Photorealistic ray tracing aids understanding of metamaterials Metamaterials have nanometer-sized structures that permit very unusual behavior of light. For example, they can exhibit indices of refraction (a measure of a medium's ability to bend light) below unity or even negative, which is not poss...
Ray-Tracing: Free e-books from Peter Shirley August 14, 2018, 02:53:39 PM QuoteIn celebration of the launch of @nvidia Turing ray tracing hardware, I am making my three ray tracing books are available as free pdfs. I have donated half the money people have sent to @hackthehood, ...
Introducing the Nebula Render In the process of preparing our 2019 Ray tracing and Rendering report, we have searched for all the ray tracing programs and suppliers we could find. The report is about geometry-based ray tracing and does not embrace field,
The difficulty of ray tracing shadows increases with the number and type of the light sources, and also the complexity of the objects causing the shadow. Even for a single point, light sources at different angles must be traced separately to show the right shadow: the more angles and lights...
Ray-tracing model for the stretching calculation of the new type aberration-free stretcher We calculated the group velocity dispersion (GVD) of the stretcher by ray-tracing model. Supposing that the distance between the grating and the center of curvature is a variable l, we obtained the variety...
