ray tracing in a sentence

Examples

1. Interference of spherical waves is usually not combined with ray tracing, thus diffraction at an aperture cannot be calculated.
2. It uses the GPU-accelerated ray tracing engine developed by the NVIDIA Advanced Rendering Center to provide interactive product visualisations.
3. Clipping ray tracing to determine with 100 % accuracy which polygons are not within the camera's field of view.
4. Deterministic methods based on the physical laws of wave propagation are also used; ray tracing is one such method.
5. Radio communicators use ray tracing to help determine the precise behavior of radio signals as they propagate through the ionosphere.
6. The ray tracing algorithm is inherently suitable for scaling by physically correct effects, providing much more realistic impression than rasterization.
7. Distributed ray tracing samples the integrand at many randomly chosen points and averages the results to obtain a better approximation.
8. Although it does handle interreflection and optical effects such as refraction accurately, traditional ray tracing is also not necessarily photorealistic.
9. It is also a useful reference for those wanting to learn how ray tracing and related geometry and graphics algorithms work.
10. Scenes in ray tracing are described mathematically by a programmer or by a visual artist ( typically using intermediary tools ).
