GLUItem Class Reference

#include <GLItems.h>

Inheritance diagram for GLUItem:

List of all members.

Detailed Description

a generic glu object.

Its drawGLDef() does nothing, but it does allow you to draw various items. A concrete subclass should implement "drawGLDef()" and call one or more of the draw-shape functions. You can also create a GLUItem and just call the draw-shape functions.

Definition at line 97 of file GLItems.h.

Slices & Stacks.

These define the subdivisions used to tesselate the quadric to a polygon.

int getSlice () const

void setSlice (int slice)

int getStack () const

void setStack (int stack)

Draw-shape, creates the geometry for a shape

void drawSphere (const gutz::vec3f &pos, float rad)

GLUItem :: draw sphere.

void drawBar (const gutz::vec3f &start, const gutz::vec3f &end, float rad)

GLUItem :: draw bar.

compile to a display list?

bool compiles () const

void setCompile (bool yes)

Public Member Functions

GLUItem (int slice=20, int stack=20)

GLUItem :: construct.

GLUItem (const GLUItem &gi)

GLUItem & operator= (const GLUItem &gi)

assign

virtual ~GLUItem ()

GLUItem :: destruct.

GLUquadricObj * getObj () const

void drawGL ()

drawGL handles some display list stuff for you, you have to call "setUP()" if the object changes and needs to have the disp list re-compiled.

void setUp (bool yes=true)

object needs update? something changed, for display lists mostly

void initNames (unsigned int name1, unsigned int name2)

gl name for picking + push "this pointer" as second name be sure to call "popNames when you are through" ...

void pushName (unsigned int name)

push a name on the pick stack, keeps track of how many you pushed so that when you call popNames() they all come off

void popNames ()

pop all names pushed on stack

void GLItem::drawGL ( ) [inherited]

drawGL handles some display list stuff for you, you have to call "setUP()" if the object changes and needs to have the disp list re-compiled.
drawGL() only calls "drawGLDef()" if the display list is being recompiled or you turn compilation off.
