Collision Object
An arbitrary number of sphere and capsule collision objects can be added to a tree. The transforms of these objects can be accessed via the SpeedTree SDK and fed to a collision detection system.
Collision Object
Type
Capsule: A cylinder capped with hemispheres. The length of the cylinder is equal to the Height value while the radius of each hemisphere is equal to the 'Radius' value. (Enumeration)
Sphere: A sphere object. The size of the sphere is determined by the 'Radius' value. (Enumeration)
Radius
The radius of a sphere collision object or the hemispherical caps of a capsule collision object.
Height
The length of the cylindrical portion of a capsule collision object. (Height)
User Data
The length of the cylindrical portion of a capsule collision object. (String)
Extra Data
A custom string can be included with each collision object. (String)
Transform
Translation: X, Y, & Z
The position of the collision object along each axis. (Float)
Reset Translation
Sets the collision object back to the default position [0, 0, 0]. (Function)
Rotation: Axis: X, Y, & Z
The X,Y, and Z components of the Rotation: Angle. (Percentage)
Rotation: Angle
The amount of rotation around the rotation angle. (Degrees)
Reset Rotation
Sets the collision object back to the default angle [0, 0, 1, 90]. (Function)
