Detailed Description

The base class for OpenGL objects.

This is the base virtual class for objects which can be displayed using OpenGL.

The class contains informations regarding the color of the object and the state of the object (selected, active, displayed, hidden). It also associates a color for each state.

Information about local transformations which should be applied to the objects are also given.

Constructor & Destructor Documentation

PLib::ObjectGL::ObjectGL (    )

The basic constructor. It sets default values for the state and the colors. The default values are defined by the default global variables: objectColorDefault, selectColorDefault, currentColorDefault and objectStateDefault.

Member Function Documentation

void PLib::ObjectGL::glNewList (    )  [virtual]

generates a default call list. Generates a default call list. It generates a call list from the glObject() call using \verb.GL_COMPILE.. Returns: The call list identification number for the object if the call was succesfull, 0 otherwise. Author: Philippe Lavoie Date: 23 September 1997 Definition at line 1337 of file nurbsGL.cpp.

void PLib::ObjectGL::glTransform (    )  const [virtual]

Performs the local transformation. Performs the local transformation in this order: scaling, translation, rotation in x, rotation in y and rotation in z. Author: Philippe Lavoie Date: 20 September 1997 Definition at line 193 of file nurbsGL.cpp.

ObjectGL & PLib::ObjectGL::operator= (  const ObjectGL &    a )

Copies another ObjectGL. Copies another ObjectGL. This will not copy the prev and next pointers. Parameters: a  the object to copy Author: Philippe Lavoie Date: 6 November 1997 Definition at line 2898 of file nurbsGL.cpp.

int PLib::ObjectGL::read (  ifstream &    fin )  [virtual]

Reads the information from a stream. Parameters: fin  the input stream Returns: 1 on sucess, 0 on failure Author: Philippe Lavoie Date: 19 June 1998 Reimplemented in PLib::PointListGL. Definition at line 3837 of file nurbsGL.cpp. References setName.

int PLib::ObjectGL::read (  const char *    filename )  [virtual]

Reads the information from a stream. Parameters: filename  the input file Returns: 1 on sucess, 0 on failure Author: Philippe Lavoie Date: 19 June 1998 Reimplemented in PLib::ObjectListGL. Definition at line 3892 of file nurbsGL.cpp.

void PLib::ObjectGL::setName (  const char *    n )

Sets the name of the object. Sets the name of the object. The content of n is copied to the name. Parameters: n  the name of the object Author: Philippe Lavoie Date: 20 September 1997 Definition at line 145 of file nurbsGL.cpp. Referenced by read, PLib::HNurbsSurfaceGL::read, PLib::NurbsSurfaceGL::read, and PLib::NurbsCurveGL::read.

char * PLib::ObjectGL::typeName (    )  const

Returns the name of the type of the class. Returns: the name of the type of the class, 0 if the type is unknown Author: Philippe Lavoie Date: 20 September 1997 Definition at line 161 of file nurbsGL.cpp.

int PLib::ObjectGL::write (  ofstream &    fout )  const [virtual]

Writes a ObjectGL to a stream. Parameters: fout  the output stream Returns: 0 if an error occurs, 1 otherwise Author: Philippe Lavoie Date: 19 June 1998 Reimplemented in PLib::PointListGL. Definition at line 3876 of file nurbsGL.cpp.

int PLib::ObjectGL::write (  const char *    filename )  const [virtual]

Writes a ObjectGL to a file. Parameters: filename  the filename to write to. Returns: 0 if an error occurs, 1 otherwise Author: Philippe Lavoie Date: 19 June 1998 Reimplemented in PLib::ObjectListGL. Definition at line 3909 of file nurbsGL.cpp.
