Detailed Description
-
class TK_PolyCylinder : public TK_Polyhedron
Handles the TKE_PolyCylinder opcode.
TK_PolyCylinder provides support for writing/reading the TKE_PolyCylinder opcode object to/from an HSF file.
The HOOPS/3dGS scene-graph can contain ‘polycylinder’ primitives which are defined by a series of points representing the centerline, radius at each point, and flags indicating which ends are ‘capped’.
Subclassed by HTK_PolyCylinder

Public Functions
-
inline TK_PolyCylinder()
constructor
-
~TK_PolyCylinder()
-
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.
-
void SetPoints(int count, float const points[] = 0)
Sets the point array. Allocates a buffer which will hold ‘count’ float triplets, and if specified, copies the ‘points’ into the buffer
-
inline float const *GetPoints() const
Returns the address of the point buffer
-
inline float *GetPoints()
Returns the address of the point buffer, which may be modified directly
-
void SetRadii(int count, float const radii[] = 0)
Sets the radius array. Allocates a buffer which will hold ‘count’ floats, and if specified, copies the ‘radii’ into the buffer
-
inline void SetRadius(float radius)
Convenience function to set a single radius
-
inline float const *GetRadii() const
Returns the address of the point buffer
-
inline float *GetRadii()
Returns the address of the point buffer, which may be modified directly
-
void SetDPoints(int count, double const points[] = 0)
Sets the point array. Allocates a buffer which will hold ‘count’ double triplets, and if specified, copies the ‘points’ into the buffer
-
inline double const *GetDPoints() const
Returns the address of the point buffer
-
inline double *GetDPoints()
Returns the address of the point buffer, which may be modified directly
-
void SetDRadii(int count, double const radii[] = 0)
Sets the radius array. Allocates a buffer which will hold ‘count’ double, and if specified, copies the ‘radii’ into the buffer
-
inline void SetDRadius(double radius)
Convenience function to set a single radius
-
inline double const *GetDRadii() const
Returns the address of the point buffer
-
inline double *GetDRadii()
Returns the address of the point buffer, which may be modified directly
-
inline int GetCount() const
Returns the number of points in the buffer
-
inline int GetRadiusCount() const
Returns the number of radii in the buffer
-
inline void SetCaps(int f)
Sets the capping options of the cylinder
-
inline int GetCaps() const
Returns the capping options of the cylinder
-
inline void SetEndNormal(int index, float const normal[] = 0)
Sets (or clears) the normal associated with an end of the polycylinder
-
inline float const *GetEndNormal(int index) const
Returns the normal associated with an end of the polycylinder (0 if none)
-
