I believe that many people are familiar with the word Renderman, every time you see a Hollywood movie, wherever there is premium animation design, it is almost inseparable from Renderman, especially in the movie that has large investment. Technically often highlight what they resolve as they faced production problems with Renderman. Such as the human realistic skin in “Final Fantasy”, the water scene in “Finding Dory”,the hair used in “Stuart Little”, etc.
So what is Renderman? RenderMan is a product that was launched by Pixar company in 19s. After several years of application, it has been increasingly favored by them. Many large animation companies have adopted it and used in their production , such as Walt Disney and Warner Pictures Corporation. The completed works that used it is everywhere now. Such as the famous world’s first three-dimensional animated film – “Toy Story”, and “Ant”, “Star Wars”, “Monster University” … …and many more.
Pixar is undoubtedly one of the world’s leading animation production company, The large part of the credit of its leading position is brought by PhotoRealistic Renderman (Prman) And the selling of Prman, bring it a lot of profit as well.
The original intention of Prman is “PhotoRealistic”, which means there is a level of accuracy of the photo. If the rendering setup is setting properly, the render output of Prman will really won’t have any jagged.
To do a the movie, the speed is a critical factor. Prman focus on the combination of speed and precision, rendering it truly be called Nurbs seamless, speed is the fastest in many renderers.Another important factor is the relation of the film production costs and profits. If the investor spend money on rendering invisible polygons, or experiment on new technologies that is not yet mature, the next time you will find no one will make movie with you. So Prman the REYES algorithm is optimized,the mission os it is render whatever you seen. Prman will ensure that it will only rendering polygon that can be seen on the screen. And never wasting time on rendering non-meeting polygons.
Pixar RenderMan is a standard graphic film industry integration (synthesis) software. It win its reputation through his fast, powerful, variable settings and programmable features, it is a powerful rendering tool using in film and generating image.
