Global lighting technology, is currently leading the game most of the lighting way he and light track different from the unit they are more subject to the buffer size limit.

Light-tracking or tracing computer graphics is one of the core algorithm. In the algorithm, the light from the light source was projectile out, when they surface after the time of their applications with all the laws of physics optical transform. Ultimately, light to enter the virtual camera film, the image was generated from. As the algorithm is the complete imaging system simulation, the simulation can generate very complex picture.

Tracking the light comes from its popular than other methods such as scanning lines rendering or rendering of light to project a more realistic simulation of light, reflection and shadow like this for some other method, it is very difficult to achieve the effect, it is the light tracking algorithm A natural result. Track lighting and visual effects easier to achieve good, so it is usually graphical programming in the areas of the first attempt.

Half-Life 3 to the images become more real, delicate, but he also has drawbacks: track lighting one of the greatest shortcomings of the performance, scanning algorithm, and other algorithms using the data to the consistency between pixels in total Enjoy, but is usually light track will be independent of each light as the light, each must be recalculated. However, this independent approach there are also some other advantages, for example, can use more light to anti-aliasing phenomenon, and when needed can improve image quality.

Although it has the right to deal with the phenomenon of mutual reflection and refraction, and other optical effects, but the traditional track lighting is not necessarily true image effect, only in very Jinsi or rendering the full realization of the equation can be achieved when the real effect of the true image. As rendering the equations describing the physical effects of each beam, so rendering equation can achieve genuine results of the true, but, taking into account the needs of computing resources, often can not be achieved.
