The Birth of a New Security Systemr light not only on their boundary, but anywhere inside their volume. Such phenomena are often called .,or .. Participating media can be imagined as some material that does not completely fill the space. Thus, the photons have the chance to go into it and to travel a random distance before collision

The dependence of the radiance of a point on all other points can be eliminated if we recognize that the illumination influence of a unit area surfa

The radiance at a given wavelength is a floating point value, and at least three wavelengths are needed to render a color image. Radiance values may differ by many orders of magnitude, i.e. they have . However, the frame buffer containing the displayed image
