Houdini is a 3D animation application software developed by Side Effects Software.
Houdini covers all the major areas of 3D production, including these:
Modeling - All standard geometry entities including Polygons, (Hierarchical) NURBs/Bézier Curves/Patches & Trims, Metaballs
Animation - Keyframed animation and raw channel manipulation (CHOPs), motion capture support
Particles
Dynamics - Rigid Body Dynamics, Computational Fluid Dynamics, Wire (Curve) Dynamics, Cloth Simulation
Lighting - node-based shader authoring, lighting and re-lighting in an IPR viewer
Rendering - supporting a variety of renderers; besides Mantra: Renderman, mental ray and various 3rd party support
Volumetrics - generations/population/manipulation/rendering of scalar- and vectorfields
Compositing - full compositor of floating-point deep (layered) images
Plugin Development - development libraries for user extensibility
Houdini is an open environment and supports a variety of scripting APIs.
Python is increasingly the scripting language of choice for the package, and is intended to substitute its original CShell-like scripting language, Hscript. However, any major scripting languages which support socket communication can interface with Houdini.
Houdini is bundled with a production-class renderer, Mantra, which has many similarities to Pixar's RenderMan (also included in Houdini 15) in its scope and application. Micropolygon rendering is supported, allowing high-quality displacement operations as well as traditional scan-line and raytracing modes.
Shaders are scriptable and composed in their VEX language, or by using VOPs; their node-based interface to programming VEX. Mantra (as does Houdini itself) also supports point-clouds, which can be similar in application as brickmaps in Renderman. This allows more complicated light interactions, such as sub-surface scattering and ambient occlusion, to be produced with lower computational overhead.
Mantra can perform extremely fast volume rendering, and also Physically Based Rendering - a technique which attempts to more accurately model the interactions of light.
