Art of Illusion is a software package used for 3D modeling, texturing, ray tracing, and otherwise rendering computer generated imagery stills or animations (movies).

The goal of Art of Illusion is to provide powerful 3D modeling tools with a user interface that improves on those found in other 3D software packages. Though its interface is simple, Art of Illusion contains many features found in high-end commercial graphics software. Some of its features, like the use of online repositories and a built-in downloading tool for installing extensions, are not found in similar proprietary software.

The primary creator and maintainer of the software is Peter Eastman.

Art of Illusion is written in the Java programming language. Distributed under the GNU General Public License, [cite web

] it is free software.

Software Features

*Interface
**Object list, scene layout windows, and animation score
**Tooltips and explanatory icons
**Bundled documentation and help interface
**Built-in "live help" chat client for connecting to the freenode Art of Illusion support channel
**Extensions available as scripts or plugins with automated installation and update from online repository (requires internet connection)
**Grid view and realtime display modes including Wireframe, Smooth, Textured.

*Modeling
**Primitives: cube, sphere, cone, tube, curve, triangle mesh, spline mesh
**Boolean modeling operations
**Lathe, sweep, extrude (straight or along a curve)
**Subdivision surfaces (smoothing) with edge creasing available for triangle meshes.
**Mesh editor featuring adjustable mesh tension, bevel, taper, various selection methods (including select edge loop/strip), etc.
**Object array tool (multidimensional arrays or arrays along a curve)
**Isosurface modeling (via procedural nodes or direct numeric input)

*Animation
**Distortion tracks for effects like bend, twist, and shatter
**Skeletal animation with weighting, constraints and IK
**Poses and Gestures
**Keyframe editor with interpolating curves
**Path animation
**Animation through scripted objects, e.g. particles using Particle Jet script

*Textures
**Types: Uniform, image mapped, procedural 2D and 3D
**Mapping options: Projection, spherical, cylindrical, UV
**Per-vertex, per-face and per-face-per-vertex texture assignment (depending on textured object)
**Layered textures
**Graphical language for procedural texture/material design
**Procedural textures can be based on parameters like view angle (for fresnel-like effects), etc.
**Animateable textures via texture parameters and use of Time module
**Environment background can be mapped with any photo (HDR or RGB), as well as procedural textures
*Materials (Represent the internal properties of an object)
**Procedural and uniform materials
**Adjustable index of refraction, scattering, eccentricity
**Animatable materials via Time module
*Rendering
**Multithreading
**Global illumination rendering, along with caustics and subsurface scattering
**Global illumination methods: Monte carlo, photon mapping with final gathering, direct photon mapping, and ambient occlusion
**Light types: Point lights, spotlights (both with editable radii), and directional lights
**Soft shadows
**Light scattering for materials: Both Single Scattering and Photon Scattering (BSSRDF). User can specify either or both at rendertime.
**Raytraced depth of field
**Gloss/translucency (blurred reflections and blurry transparency)
**Motion blur
**HDRI scene illumination
**Save renders as HDRI images

*Post Processing
**Camera filters (Exposure Correction, Glow, Outline, Tint, Blur, etc.)
**Noise reduction for Global Illumination

*Scripting
**Scripting language (Beanshell) allowing development of new tools/commands
**Dynamic Scripts ("smart objects" - see [http://aoi.sourceforge.net/docs/scripttut/chapter5.html flyswatter tutorial] )

*File Handling
**3D Import: .obj natively; .dem, .dxf, .geo, .lwo, .pov, .inc, .3ds via plugins
**2D Import via scripts: .ai, .svg
**3D Export: .pov, .obj, VRML, all native; .stl via plugin
**2D Export/Save: .jpg, .bmp, .png, .tif, .hdr, all native; .svg via plugin

*Extended Functionality Through Scripts and Plugins
**Direct-to-disk rendering using presets like "Letter," "A4," with DPI and Bleed settings (Advanced Rendering plugin)
**Wireframe/polygon renders with antialiasing and SVG export ( [http://aoisp.sourceforge.net/plugins/vectorrenderer.html Vector Renderer] plugin)
**Preview renders in sidebar (Preview Plugin)
**Subdivision (Ngon) modeler with tools for both open- and closed-mesh modeling and support for Catmull-Clark subdivision surfaces ( [http://aoisp.sourceforge.net/plugins/polymesh.html Polymesh Editor] plugin)
**ABF+ UV unwrapping available through Polymesh Editor plugin
**Procedural tree and plant creator ( [http://aoisp.sourceforge.net/plugins/tapd.html Tree and Plant Designer] plugin)
**Other major features provided through script or plugin extensions such as: 3D text, mesh thickening, platonic solids, sculpt, fractal/image-based heightfields, hair, grunge, and more

Development

*Art of Illusion is a free and open source application and contributions to the source code, scripts and plugins base, and other aspects of the software are welcome.
*Art of Illusion's development cycle usually includes two builds called "Early Access" (EA) releases followed by a Beta, or "bug fix" version. However, with a recent [http://sourceforge.net/forum/forum.php?thread_id=1425763&forum_id=47782 announcement] , the bug-fixing portion of development has been shifted to make sure that more bugs are fixed in existing features.
*Developers are welcome to submit scripts and plugins via email to maintainers of the [http://aoisp.sf.net Scripts and Plugins Repository] for inclusion in the online repository. This ensures that users will be able to download scripts and plugins easily from within Art of Illusion itself.
*Developers with code to contribute to AoI itself should submit it to Peter Eastman for approval and inclusion. [http://sourceforge.net/forum/message.php?msg_id=3243782 More information]
*Non-code contributions can be made as well. [http://aoi.sourceforge.net/contribute Details] (Note that the Smartgroups link on that page is obsoleted by the Scripts and Plugins Repository)

IRTC Competition

The [http://www.irtc.org Internet Ray Tracing Competition] is an online computer graphics competition. Several Art of Illusion users have submitted entries to the competition.
*Nate Ryan's [http://www.housepixels.com/aoitiki/tiki-browse_image.php?galleryId=2&imageId=10 Fungus Dance] image won 1st place in the September - October 2003 "Decay" contest. [http://www.irtc.org/stills/2003-10-31.html link]
*Julian MacDonald's "Gladiators" animation won Honorable Mention: Artistic Merit in the July-October 2004 contest. [http://www.irtc.org/anims/2004-10-15.html link]
* [http://www.irtc.org/ftp/pub/stills/2004-10-31/jmactoys.jpg"Bathtime Fun"] , also by Julian MacDonald, won 2nd place in the September-October 2004 contest. [http://www.irtc.org/stills/2004-10-31.html link]
*Kevin Lynn's "Is Juggling a Sport?" animation won 1st place in the July-October 2005 contest. [http://www.irtc.org/anims/2005-10-15.html link]
**Kevin is continuing an Art of Illusion tradition by offering a [http://sourceforge.net/forum/message.php?msg_id=3512782 box of chocolates] to the next winner of an online graphics competition using Art of Illusion.
