This has led to a higher learning curve than other comparable tools. Houdini's set of tools are mostly implemented as operators. In this way Houdini can be regarded as a highly interactive visual programming toolkit which makes programming more accessible to artists. In this way users can create their own sophisticated tools without the need for programming. This node graph architecture is similar to that employed in node-based compositors such as Shake or Nuke.Ĭomplex networks can be grouped into a single meta-operator node which behaves like a class definition, and can be instantiated in other networks like any compiled node. This data could represent 3D geometry, bitmap images, particles, dynamics, shader algorithms, animation, audio, or a combination of these. Data flows through, manipulated by each operator in turn.

Operators are connected together in networks.

LOPs - Lighting Operators - for generating USD describing characters, props, lighting, and rendering.

VOPs – VEX operators – for building nodes of any of the above types using a highly optimized SIMD architecture.

ROPs – render operators – for building networks to represent different render passes and render dependencies.

SHOPs – Shading Operator – for representing a dozen or more different shading types for several different renderers.

DOPs – Dynamic Operators – for dynamic simulations for fluids, cloth, rigid body interaction etc.

COPs – Composite Operators – used to perform compositing on footages.

CHOPs – Channel Operators – for procedural animation and audio manipulation.

POPs – Particle Operators – used to manipulate particles systems.

SOPs – Surface Operators – for procedural modelling.

OBJs – nodes that pass transform information (Traditionally these contain SOPs.).

Houdini's operator-based structure is divided into several main groups: Houdini uses this procedural generation in production of textures, shaders, particles, "channel data" (data used to drive animation), rendering and compositing. This proceduralism has several advantages: it allows users to construct highly detailed geometric or organic objects in comparatively very few steps it enables and encourages non-linear development and new operators can be created in terms of existing operators, a flexible alternative to non-procedural scripting often relied on in other packages for customisation. Digital assets are generally constructed by connecting sequences of operators (or OPs). Houdini's procedural nature is found in its operators. However, any major scripting languages which support socket communication can interface with Houdini. Python is increasingly the scripting language of choice for the package, and is intended to substitute its original CShell-like scripting language, Hscript. Houdini is an open environment and supports a variety of scripting APIs.

Plugin Development – development libraries for user extensibility.

SideFX also publishes Houdini Apprentice, a limited version of the software that is free of charge for non-commercial use. It has been used in many feature animation productions, including Disney's feature films Fantasia 2000, Frozen, and Zootopia the Blue Sky Studios film Rio, and DNA Productions' Ant Bully. It is used by major VFX companies such as Walt Disney Animation Studios, Pixar, DreamWorks Animation, Double Negative, ILM, MPC, Framestore, Sony Pictures Imageworks, Method Studios and The Mill.

Houdini is most commonly used for the creation of visual effects in film and games. Some of its procedural features have been in existence since 1987. The procedural tools are used to produce different effects such as complex reflections, animations and particles system. Houdini is a 3D animation software application developed by Toronto-based SideFX, who adapted it from the PRISMS suite of procedural generation software tools.
