Speedtree是一款专门的三维树木建模软件，支持大片的树木的快速建立和渲染，而且它本身还带有强大的树木库，软件是由美国IDV公司研发制作的。不仅可以通过插件将树木导入到其他的三维建模软件中使用，也可以为游戏引擎提供强大的树库支持，目前已经成为著名游戏引擎Unreal的御用树木生成软件。
SpeedTree因为它的实时几何体建模技术而在游戏行业闻名，并且因为树叶的制作而成为了电影与电视行业的主要工具。虽然这个程序对电影与广播行业来说还是个新的品牌，但这个工具在游戏行业已经是反复使用了，从而能够制作出各种丰富成熟的功能。SpeedTree被认为是电影阿凡达中不可或缺的一个工具。
工业光魔采用SpeedTree Cinema软件来制作电影《阿凡达》中潘朵拉星球上的树木场景。IDV的新版本软件SpeedTree Studio已经上市，售价895美元。
IDV已经推出了Speed Tree Studio，这是SpeedTree Cinema树木制作软件的实惠版本，价格会有所下降。新产品将这项技术的价格从4995美元降到895美元。
SpeedTree Studio有许多SpeedTree Cinema中的功能，包括用程序或是手绘来制作树木的选项，还有模拟风的效果的选项；但是缺少浮动许可证，世界的构建，直接研发支持和64-bit版本。
产品中附带了5个树木模型，但是您可以在网上从SpeedTree Model Library中购买更多的模型。
新功能包括：
•风效向导
根据用户的最低限度，自动计算风的参数。
•属性类别
类别按钮位于复杂对象属性的顶端，用于加速属性编辑。
•网格简单化以及材料导入
在任何地方，只要能将网格和材料分配到树组件上，那么就可以实现一步导入、创建和分配属性；同时可将网格和材料的导入选项加到“文件”菜单上。
•导出时结构的转换
在导出时可将结构转换成用户选择的格式。
•对安全框的截图
现在通过“树窗口”属性可以实现对要截图的“安全框”进行渲染。该功能还可以显示，应用在下一张图像上的区域或材料的导出。

SpeedTree is a suite of 3D-modeling tools that combines the efficiency of procedural modeling with the flexibility of hand modeling. Since its launch in 2001, SpeedTree has been used in hundreds of AAA and indie games and more than a hundred movies and television episodes. The software has earned a Scientific and Technical Academy Award and an Engineering Emmy, both in 2015.
New Features
Mesh-Based Smooth Normals
Leaf and frond meshes have new lighting properties allowing them to compute smooth normals based on the mesh after procedural deformation has been applied (this was only approximated in previous versions).
Improved Quadification
Quad indices for triangle only meshes are computed with a new, faster algorithm that creates more evenly distributed quads. This is particularly noticeable on high poly meshes.
Bug Fixes
File Dialog Crash
The crash associated with previously available drives no longer being accessible has been fixed.
Lumberyard Face Winding
The face winding for Lumberyard exports has been modified to work with both the vegetation shaders (this always worked) and non two-sided shaders.
Unwrapping Fixes
A bug where shell generators could be mapped incorrectly during unwrapped exports has been corrected. Small items that were scaled up could cause overlapping in the atlas – this issue has also been corrected. In addition, an improvement has been made in the algorithm to prevent the unwanted expansion of tiny details.
