## Detailed Description

class `TK_Sphere` : public BBaseOpcodeHandler

  Handles the TKE_Sphere opcode.

  TK_Sphere provides support for writing/reading the TKE_Sphere opcode object to/from an HSF file.

  The HOOPS/3dGS scene-graph can contain ‘sphere’ primitives which are defined by the center point the radius, two vectors to dictate where tessellation should begin.

  Public Types

  enum `Flags`

    Defines various capping options

    Values:

    enumerator `TKSPH_NONE`

      no special handling

    enumerator `TKSPH_NULL_AXIS`

      omit axis and ortho, in favor of default values of <0,1,0>,<1,0,0>

  Public Functions

  inline `TK_Sphere`()

    constructor

  virtual TK_Status `Read`(BStreamFileToolkit &tk)

    Reads data from the toolkit buffer, decodes/decompresses it, and maps it to the opcode handlers data members. User-defined classes which need to write out custom data should utilize one of the available GetData() methods.

    Parameters: | tk – A reference to the BStreamFileToolkit object.
    Returns: | The result of the function call.

  virtual TK_Status `Write`(BStreamFileToolkit &tk)

    Encodes/compresses data and writes data to the toolkit buffer. User-defined classes which need to write out custom data should utilize one of the available PutData() methods, and first write out the opcode associated with the group of binary data followed by the data itself.

    Parameters: | tk – A reference to the BStreamFileToolkit object.
    Returns: | The result of the function call.

  virtual TK_Status `Clone`(BStreamFileToolkit &tk, BBaseOpcodeHandler **handler) const

    Copies the opcode handler

    Parameters: | tk – A reference to the BStreamFileToolkit object. handler – A pointer to the opcode handler object. Passed by reference.
    Returns: | The result of the function call.

  TK_Status `ReadAscii`(BStreamFileToolkit &tk)

    Deprecated.

  TK_Status `WriteAscii`(BStreamFileToolkit &tk)

    Deprecated.

  virtual void `Reset`()

    Resets the current opcode handler. This is called by the toolkit when it is done processing an opcode. This method reinitializes any opcode handler variables and frees up temporary data.

  inline void `SetCenter`(float x, float y, float z)

    Sets the center of the sphere using discrete float values

  inline void `SetCenter`(float const s[])

    Sets the center of the sphere using a float array

  inline float const *`GetCenter`() const

    Returns the center as the address of a float array

  inline void `SetRadius`(float r)

    Sets the radius of the sphere

  inline float `GetRadius`() const

    Returns the radius of the sphere

  inline void `SetAxis`(float x, float y, float z)

    Sets the axis of the sphere using discrete float values

  inline void `SetAxis`(float const s[])

    Sets the axis of the sphere using a float array

  inline float const *`GetAxis`() const

    Returns the axis as the address of a float array

  inline void `SetOrtho`(float x, float y, float z)

    Sets the ortho of the sphere using discrete float values

  inline void `SetOrtho`(float const s[])

    Sets the ortho of the sphere using a float array

  inline float const *`GetOrtho`() const

    Returns the ortho as the address of a float array

  inline void `SetDCenter`(double x, double y, double z)

    Sets the center of the sphere using discrete double values

  inline void `SetDCenter`(double const s[])

    Sets the center of the sphere using a float array

  inline double const *`GetDCenter`() const

    Returns the center as the address of a float array

  inline void `SetDRadius`(double r)

    Sets the radius of the sphere

  inline double `GetDRadius`() const

    Returns the radius of the sphere

  inline void `SetDAxis`(double x, double y, double z)

    Sets the axis of the sphere using discrete double values

  inline void `SetDAxis`(double const s[])

    Sets the axis of the sphere using a double array

  inline double const *`GetDAxis`() const

    Returns the axis as the address of a double array

  inline void `SetDOrtho`(double x, double y, double z)

    Sets the ortho of the sphere using discrete double values

  inline void `SetDOrtho`(double const s[])

    Sets the ortho of the sphere using a double array

  inline double const *`GetDOrtho`() const

    Returns the ortho as the address of a double array
