Inspector used to rotate a Model based on where it is "grabbed" in screen coordinates (e.g., from a mouse click) Evaluator that moves a Camera and modifies is attributes so that the Camera's view frustum is shaped to fit only the given target's boundingBox Effector that modifes vertices and normals n order to create jointed movement for a Bone Simulator that mimics basic flight Evaluator that shades vertices (set vertexColors) by isolating a scalar value and interpolating between points Effector that modifies the vertices and normals of a non-indexed Geometry such that it morphs from one form to another form having the same number of vertices Evaluator that clamps the heading and/or pitch of one or more ParentableMotionElements such that they are always facing the target Evaluator that clamps the heading and/or pitch of a moving ParentableMotionElement to the heading and/or pitch of a motion path (i.e., cancels object-relative heading) Inspector used to pan, zoom, and rotate a Camera Evaluator that outputs an interval of system time in milliseconds between calls to Evaluate Evaluator that updates the position and rotation of a ParentableMotionElement given an elapsed time, a linear velocity value, and angular velocity values for degrees of rotation about an axis Simulator that jitters the camera as if it were hand-held
