Advantages
One of the advantages of the Radiosity algorithm is that it is relatively simple to explain and implement. This makes it a useful algorithm for teaching students about global illumination algorithms. A typical direct illumination renderer already contains nearly all of the algorithms (perspective transformations, texture mapping, hidden surface removal) required to implement radiosity. A strong grasp of mathematics is not required to understand or implement this algorithm.

Famous quotes containing the word advantages:
“Men hear gladly of the power of blood or race. Every body likes to know that his advantages cannot be attributed to air, soil, sea, or to local wealth, as mines and quarries, nor to laws and traditions, nor to fortune, but to superior brain, as it makes the praise more personal to him.”
—Ralph Waldo Emerson (1803–1882)
“... is it not clear that to give to such women as desire it and can devote themselves to literary and scientific pursuits all the advantages enjoyed by men of the same class will lessen essentially the number of thoughtless, idle, vain and frivolous women and thus secure the [sic] society the services of those who now hang as dead weight?”
—Sarah M. Grimke (1792–1873)
“[T]here is no Part of the World where Servants have those Privileges and Advantages as in England: They have no where else such plentiful Diet, large Wages, or indulgent Liberty: There is no place wherein they labour less, and yet where they are so little respectful, more wasteful, more negligent, or where they so frequently change their Masters.”
—Richard Steele (1672–1729)
