IDV releases SpeedTree 9.5
IDV has released SpeedTree 9.5, the latest version of its line of software for generating 3D trees.
The update makes it possible to manipulate parts of a leaf individually, adds a new Projectors system for adding details like moss or snow, and extends support for height maps.
A production-proven toolset for authoring 3D trees for games and visual effects
Released over two decades ago, and now owned by Unity, SpeedTree generates textured, wind-animated 3D trees for real-time and offline work, using a combination of procedural generation and manual editing.
Both include SpeedTree Modeler, the actual plant-authoring software, and SpeedTree Library, a library of readymade 3D plants. SpeedTree Games also includes the SpeedTree SDK.
SpeedTree 9.5: new Frond editing workflow lets you adjust parts of a leaf individually
New features in SpeedTree 9.5 include the option to manipulate sections of Fronds individually.
Users can now isolate parts of a leaf, like individual leaflets in compound leaves, by masking them in the Cutout Editor, then apply procedural changes.
Suggested use cases include randomising the look of leaves by curling sections, or having forces like wind and gravity affect sections differently.
SpeedTree 9.5: add moss or snow to trees with Projectors
Other new features include Projectors, a new system for adding procedural details to models.
It uses ray casting to create the distribution pattern, projecting light rays into the scene, and generating details wherever the rays strike a surface.
On trees themselves, that makes it possible to create natural-looking directional effects, like moss only growing up one side of the trunk, or snow settling on branches from above.
It can also be used to scatter objects on the ground surrounding a tree, as shown in the video above.
SpeedTree 9.5: greater support for height maps and updates to the paint tools
Other changes include support for height maps in the Leaf, Batched leaf and Frond generators.
As well as being a way of adding detail to parts of a tree, IDV says that the change “allows you to identify subsections on a mesh via … the Cutout editor, eliminating the need for external modeling software”.
The paint tools have also been improved, with new options including brush size, falloff, and opacity margin.
SpeedTree 9.1 to 9.4: global lighting properties and new Decal and Mesh detail generators
Since we last wrote about SpeedTree, IDV has also added a number of other features.
Other changes since SpeedTree 9.0 include new Decal and Mesh detail generators, for generating surface details, and the option to add perspective and orthographic cameras and save them as part of a scene.
