SpeedTree is a group of vegetation programming and modeling software products developed and sold by Interactive Data Visualization, Inc. (IDV) that generates virtual foliage for animations, architecture and in real time for video games and demanding real time simulations such as the Trainz series. It has been licensed to developers of a range of video games for PC, Xbox 360 and PlayStation 3 and has been featured in movies including 2013's Jack the Giant Slayer, 2012's Life of Pi and Snow White and the Huntsman, and 2009's Avatar.
Origins and History 
In a "Postmortem" feature on Gamasutra.com, Kevin Meredith of IDV recounted SpeedTree as originating due to their lack of satisfaction with 3rd-party plug-ins on the market. The initial version of SpeedTreeCAD (CAD standing for "computer-aided design") was developed by IDV for a real-time golf simulation. Although backers pulled out of the golf project, IDV refined the CAD software as a 3D Studio Max component for an animated architectural rendering. After refining SpeedTreeMAX for retail, IDV went on to produce the real-time version SDK version to much commercial success.
IDV released SpeedTree v5.0 in July 2009. v5.0 represented a "complete re-engineering" of the software, according to an IDV announcement in March 2009, and features a new set of components: SpeedTree Modeler (replacing SpeedTreeCAD) and SpeedTreeSDK (replacing SpeedTreeRT), as well as SpeedTree Compiler, which prepares SpeedTree files for real-time rendering. The same components are featured with Version 6 of the product, released in November 2011 and identified as SpeedTree for Games to distinguish it from other products not meant for gaming/real-time use.
Products and Components 
On August 3, 2011, IDV announced the release of SpeedTree version 6 technology and its inclusion in two products, SpeedTree Cinema and a new product SpeedTree Studio. SpeedTree Cinema was first released by IDV in 2009, based on version 5 technology, and is meant for high-end movies and animations. SpeedTree Studio licenses at a lower price and offers fewer features than SpeedTree Cinema. SpeedTree for Games, featuring version 6 technology, was released on November 7, 2011. SpeedTree Architect was released on October 15, 2012 and offers a more limited version of SpeedTree Studio for architectural stills and fly-throughs.
SpeedTree SDK is a software development kit written in C++ whose source code is available to licensees of SpeedTree for Games for use in video games and other real-time applications. It is intended to be fitted into a larger graphical engine, with the SpeedTree software handling the rendering of trees and foliage alone and the specific product's engine incorporating these into the larger environment.
SpeedTree Modeler is a Windows-based specialized modeling tool created specifically for creating and editing foliage. SpeedTree Modeler permits specification of such variables as branch length, branching angles, bark texture and gravitational influence, and then generates a tree from that information in a variety of static mesh or real-time formats. Trees created in SpeedTree Modeler can be more or less detailed, and consequently can be used for either real-time or prerendered display.
SpeedTree Compiler is a component of SpeedTree for Games used with SpeedTree SDK for real-time projects. It facilitates the creation of texture atlases and compiles and optimizes tree models for real-time use.
SpeedTreeMAX was launched in February 2002, and SpeedTreeRT was licensed for its first titles, including The Elder Scrolls IV: Oblivion, in December 2002. SpeedTree has been licensed for PC and next-generation console titles in a wide variety of genres by developers including:
SpeedTree has partnered with Epic Games in order to integrate the software with Epic's Unreal Engine 3 and the free UDK engine released in November 2009. Partnerships have also been formed between SpeedTree and BigWorld Tech, the Vision Engine by Trinigy, Multiverse Network, the Gamebryo engine by Emergent Game Technologies and the OGRE open-source rendering engine by Torus Knot.
Recent releases 
Other games 
This list is incomplete, and may never satisfy certain standards for completion, as many game developers do not reveal their use of middleware, or will not announce the tools they have used until the game is released.
Real-time non-game applications 
SpeedTree is being used in the following real-time, non-game projects and offerings:
- America's Army project, both the America's Army game and in non-public applications used for training, simulation, education, virtual prototyping and outreach
- An optional foliage module with the Vega Prime visualization product line (official announcement) developed by MultiGen-Paradigm, Inc. (now Presagis) prior to its acquisition by CAE in May 2007. Vega Prime is a 3D visual simulation software package used by the global military industry and in other game and non-game markets
