Space Time Ray Tracing using Ray Classification
Throughout the history of computer graphics, a very active area of research has been the attempt to create convincing, life-like images. Ray tracing is a technique for generating photorealistic images, and can easily support a wide range of natural phenomenon. However, producing a ray traced image is very expensive; and producing a ray traced animation is often prohibitively expensive. This the...

متن کاملTime and Space Efficient Grids for Ray Tracing
The focus of research in acceleration structures for ray tracing recently shifted from render time to time to image, the sum of build time and render time, and also the memory footprint of acceleration structures now receives more attention. In this paper we revisit the grid acceleration structure in this setting. We present two efficient methods for representing and building a grid. The minimu...
متن کاملAcoustic Ray-Tracing on Unstructured Adaptive Grids
A computationally efficient acoustic ray-tracing code based on unstructured adaptive grids is described in detail. The use of unstructured grids allows wave propagation simulations on complex computational domains. Detailed surface layer physics is included to take into account the atmospheric variability under different stability conditions and landuse inhomogeneities. The ray-tracing model ha...
متن کاملRay Tracing for Ocean Acoustic Tomography
This report describes a new, flexible computer code in the FORTRAN computer language to make ray calculations for ocean acoustic tomography. The Numerical Recipes software package provided the basis for much of this computer code. The ray equations are reviewed, and ray equations that include the effects of ocean current are derived. Methods are derived for rapidly integrating those equations t...
