From Solid Graphics Wiki
The ObjectPosInfo class is a class used in SolidKit Library to specify an 3D object position. This and the ObjectPosInfoList class are the only types required to "connect" nonSolidKitLibrary datamodel objects with the Control3D class, so the Control3D object can be used to manipulate the "outside datamodel" objects.
Fields
Field name
 Type
 Description

Translation
 SolidKit3D.Vector
 position of the object described by this ObjectPosInfo class instance

Rotation
 SolidKit3D.Vector
 rotation of the object

CenterPoint
 SolidKit3D.Point
 center point of the object rotation

BoundingSphereRadius
 float
 bounding sphere radius of the object. This field must be set by the calling application before pasing the object position/rotation for manipulation to the Control3D class.

Tag
 object
 Custom data pointer which can be set by an aplication to anything

Methods
Note: Most of the below methods have two versions  one version uses the .NET math floating point operations to perform calculations. The second version uses method name postfix OGL and uses OpenGL functions to perform the calculations  which potentially allows graphics card hardware acceleration for the calculations.
Initialize
 Initialize the field values.

ObjectToWorld
 Depending on the used parameter type  the method translates a point coordinates from coordinate system relative to the object to world (scene) coordinates, or modifies given matrix so it can be used to perform such translation later on.

WorldToObject
 Depending on the used parameter type  the method translates a point coordinates from world (scene) coordinates to coordinate system relative to the object, or modifies given matrix so it can be used to perform such translation later on.

ObjectVectorToWorldVector
 Transforms a rotation vector from coordinate system relative to the object to rotation in world (scene) coordinate system.

WorldVectorToObjectVector
 Transforms a rotation vector from world (scene) coordinate system to rotation in coordinate system relative to the object.

ObjectRotationToWorldRotation
 Modifies given matrix so it can be used for transforming a rotation vector from coordinate system relative to the object to rotation in world (scene) coordinate system.

WorldRotationToObjectRotation
 Modifies given matrix so it can be used to transform a rotation vector from world (scene) coordinate system to rotation in coordinate system relative to the object.

MatchPoint
 Changes translation of the object so it's specified point moves to another point specified on another object.

MatchDirection
 Changes rotation of the object so it's specified vector matches direction of another vector specified on another ObjectPosInfo object

RotateAroundAxis
 Changes rotation of the object by rotating it by specified angle around specified axis vector.

RotateAroundAxisUsingAxisAngles
 Changes rotation of the object by rotating it by specified angle around specified axis vector. The axis vector is specified by it's angles relative to coordinate system, rather than by vector values.

BoundingBox
 Returns bounding box of a 3D object which position is specified by the ObjectPosInfo instance. The instance's boundingSphereRadius field value must be provided by the application in order to calculate the bounding box correctly.

Scale
 Scales the instance's Translation, CenterPoint and BoundingSphereRadius fields by given factor.

SetCenterPoint
 Set's new centerPoint for an object and recalculates the object's translation so the 3D object position relative to world/scene will remain unchanged.

LoadFromXML
 Loads ObjectPosInfo instance's fields from given XmlReader.

SaveToXML
 Saves ObjectPosInfo instance's fields to given XmlWriter object.

Operators
The ObjectPosInfo class type has no operators.
