Renderizacion con RenderMan

RenderMan is actually a technical specification for interfacing between modeling and rendering programs. From 1998 until 2000 the published RenderMan Interface Specification was known as Version 3.1. In 2000 Pixar published a new specification, Version 3.2.

There are a lot of people when you hear them talking about RenderMan and how great the images are from it, etc. They are most likely really talking about Pixar's PhotoRealistic RenderMan® (PRMan).

So the reasons for this confusion between RenderMan the spec and PRMan the renderer are:

  1. Pixar publishes and owns the RenderMan Interface Specification
2. RenderMan is a registered trademark of Pixar.
3. Pixar had the first implementation (PRMan).
4. PRMan has been used in a lot of movies.
5. Not only was PRMan the first implementation of the RenderMan


Specification, it was for many years the only implementation.
RenderMan Interface Bytestream (RIB), very simply, is the file format used to pass scene information (model data, lights, camera, shaders, attributes, and options) to a RenderMan renderer to control image that it will render. At the 2003 SIGGRAPH, Dana Batali (Director or RenderMan Product Development at Pixar) shared an interesting historical slide showing some of the major milestones on evolution of RIB. (which has been around publicly for 15+ years)



Es interesante todo esto que lei y aprendi de la pagina oficial www.renderman.org

RenderMan & Motion Builder

Es curioso ver que software usado para renderizar y crear animaciones usa algoritmos muy parecidos a los que yo uso comunmente en mis simulaciones matematicas, algo que para mi es comun como transformada de fourier, wavelets, conceptos sobre procesamiento de video y todo lo referente a DSP o procesamiento digital de señales.

Tal vez tenga que redirigir mis objetivos por motivos economicos, pero podria ser un buen cambio y eso me permitira explorar las artes graficas un poco mejor.
