Overview of The Software
Autodesk Softimage is a 3D animation application that contains tools for a wide range of production steps.
Modeling tools allow the generation of polygonal or NURBS models. Subdivision modeling requires no additional operators and works directly on the polygonal geometry. Each modeling operation is tracked by a construction history stack, which enables artists to work non-destructively. Operators in history stacks can be re-ordered, removed or changed at any time, and all adjustments propagate to the final model.
Control rigs are created using bones with automatic IK, constraints and specialized solvers like spine or tail. Optionally, the ICE system can be used to create light-weight rigs in a node-based environment. The rigging process can be sped up through the use of adaptable biped and quadruped rigs, FaceRobot for facial rigs and automatic lip syncing.
Animation features include layers and a mixer, which allows combining animation clips non-linearly. Animation operators are tracked in a construction history stack that is separate from the modeling stack, enabling users to change the underlying geometry of already animated characters and objects. MOTOR is a feature that transfers animation between characters, regardless of their size or proportions. GATOR can transfer attributes such as textures, UVs, weight maps or envelopes between different models. Softimage also contains tools to simulate particles, particle strands, rigid body dynamics, soft body dynamics, cloth, hair and fluids.
The default and tightly integrated rendering engine in Softimage is mental ray. Materials and shaders are built in a node-based fashion. When users activate a so-called render region in a camera view, it will render this section of the scene using the specified rendering engine and update completely interactively. A secondary rendering mode is available for rendering real-time GPU shaders written in either the Cg or HLSL languages.
Also included is the FX Tree, which is a built-in node-based compositor that has direct access to image clips used in the scene. It can thus not only be used to finalize and composite rendered frames, but also as an integral part of scene creation. The FX Tree can be used to apply compositing effects to image clips being used in the fully rendered scene, allowing Softimage to render scenes using textures authored or modified in various ways within the same scene.
In addition to the node-based ICE platform described below, Softimage has an extensive API and scripting environment that can be used to extend the software. The available scripting languages include C#, Python, VBScript and JScript. A C++ SDK is also available for plug-in developers, with online documentation available to the public.
