Utility functions
The following utility functions are available
void GLwBeginProjection (Widget w)
void GLwEndProjection (void)
The following code snippet selects perspective
projection for the workstation ws:
GLwBeginProjection (ws);
glFrustum (-1.0, 1.0, -1.0, 1.0, 1.0, 10.0);
GLwEndProjection ();
During redisplay, this will be executed as a display
list with the matrix mode set to GL_PROJECTION and an
identity matrix on top of the projection matrix stack.
void GLwPostProjectionList (Widget w, GLuint p)
void GLwPostProjectionMatrix (Widget w, GLdouble *m)
void GLwPostCurrentProjection (Widget w)
void GLwUnpostProjection (Widget w)
GLuint GLwGetProjectionList (Widget w)
int GLwGetProjectionMatrix (Widget w, GLdouble *m)
void GLwSetFrustumProjection (Widget w, GLdouble left,
GLdouble right, GLdouble bottom, GLdouble top,
GLdouble near, GLdouble far)
GLdouble right, GLdouble bottom, GLdouble top,
GLdouble near, GLdouble far)
void GLwBeginView (Widget w)
void GLwEndView (void)
The following code snippet selects a view from the z-
axis for the workstation ws:
GLwBeginView (ws);
gluLookAt (0.0, 0.0, 3.0,
0.0, 0.0, 0.0,
0.0, 1.0, 0.0);
GLwEndView ();
During redisplay, this will be executed as a display
list with the matrix mode set to GL_MODELVIEW and an
identity matrix on top of the model view matrix stack.
void GLwPostViewList (Widget w, GLuint v)
void GLwPostViewMatrix (Widget w, GLdouble *m)
void GLwPostCurrentView (Widget w)
void GLwUnpostView (Widget w)
GLuint GLwGetViewList (Widget w)
int GLwGetViewMatrix (Widget w, GLdouble *m)
void GLwSetPolarView (Widget w, GLdouble r, GLdouble
theta, GLdouble phi)
void GLwPostObject (Widget w, GLuint o)
posts object to w.
void GLwUnpostObject (Widget w, GLuint o)
void GLwUnpostAllObjects (Widget w)
void GLwRedrawObjects (Widget w)
force a redraw of all objects posted to w.
