# Object sample atom

An atom that describes a single object.

## Overview

Overview An object sample atom describes a single object, including information about the default viewing angles and the view settings. The structure of an object sample atom is defined by the QTVRObjectSampleAtom data type: typedef struct VRObjectSampleAtom {     UInt16                              majorVersion;     UInt16                              minorVersion;     UInt16                              movieType;     UInt16                              viewStateCount;     UInt16                              defaultViewState;     UInt16                              mouseDownViewState;     UInt32                              viewDuration;     UInt32                              columns;     UInt32                              rows;     Float32                             mouseMotionScale;     Float32                             minPan;     Float32                             maxPan;     Float32                             defaultPan;     Float32                             minTilt;     Float32                             maxTilt;     Float32                             defaultTilt;     Float32                             minFieldOfView;     Float32                             fieldOfView;     Float32                             defaultFieldOfView;     Float32                             defaultViewCenterH;     Float32                             defaultViewCenterV;     Float32                             viewRate;     Float32                             frameRate;     UInt32                              animationSettings;     UInt32                              controlSettings; } VRObjectSampleAtom, *VRObjectSampleAtomPtr; QT QT QT
