Pixar’s RenderMan has been specifically engineered to meet the demanding challenges of rendering 3D animation and visual effects. This means RenderMan is fast, efficient, and able to handle an astonishing amount of geometric complexity along with offering cutting-edge effects. Critically, Pixar’s RenderMan has been developed to deliver outstanding imagery during the stresses of real-world productions. This means that in your own 3D work, you can trust that RenderMan is ready for the job … with not only outstanding features, but the power to deliver.
Introduction: Renderman@ is a specification, prman is the software : a brief history of this 20 years old software – quick tour of the prman software package and the various utilities – “hello sphere” : write a simple RIB to render a sphere – overview of the structure of a RIB – context stacks.
RIB structure : creating a scene – basic transformations (and matrix concatenation) – positioning the camera – basic geometric primitives – parenting – options & attributes.
REYES: in-depth look at the REYES algorithm, does it really Render Everything You Ever Saw ? – core concepts : splitting, dicing, micropolygons and shaders – render options : taking control of your memory, speed and image quality
Custom Shaders: introduction to the shading language grammar, syntax & data types, compilation – implementation of a simple plastic shader – implementation of a simple light shader – attaching the shaders to the geometry.
ImageFeatures: motion blur, motion samples, multi-segment blur, limitations – depth of field – uniform / varying – flow control – fBm
Passing Data: coordinate systems, space transformations
Shading, texture maps: txmake and texture( ) – geometric primitives – texture coordinates
Shading, Illumination: Illuminance, Illuminate : diffuse & specular reflections
Bump & Displacement: bump mapping – displacement mapping – displacement bounds – practical application of sub-pixel displacement
Shadows: shadow maps – bias – blur – samples – workflow in Maya / Slim
