##### 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 SpeedTreeRT API and fed to a collision detection system.

# Collision Object

## enumeration 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.

### Sphere

A sphere object. The size of the sphere is determined by the Radius value.

## float Radius

The radius of a sphere collision object or the hemispherical caps of a capsule collision object.

## height Height

The length of the cylindrical portion of a capsule collision object.

## string 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.

# Transform

## float Translation: X, Y, & Z

The position of the collision object along each axis.

## percentage Rotation: Axis: X, Y, & Z

The X,Y, and Z components of the Rotation: Angle.

## degrees Rotation: Angle

The amount of rotation around the rotation angle.
