31. Important topics in computer graphics include user interface design, ray tracing , and computer vision, among others. 32. They do use ray tracing for acoustics sometimes; see Ray tracing ( physics ) # Ocean acoustics. 33. For a recent broad discussion on ray tracing in the ionosphere see Bennett " et al ". 34. They do use ray tracing for acoustics sometimes; see Ray tracing ( physics ) # Ocean acoustics. 35. A notable example is highly optimized ray with axis aligned box intersection code in ray tracing ). 36. Another way of computing the propagation of waves in the plasma medium is by using Ray tracing method. 37. For example, ray tracing involves performing the same task over and over on a large set of numbers. 38. It's an open-source ray tracing program. 39. Before the advent of the computer, ray tracing calculations were performed by hand using trigonometry and logarithmic tables. 40. Tachyon was shown as a demo performing interactive ray tracing on DEC Alpha workstations using KCC and OpenMP.
