Detailed Description

gobjContainer is a generic graphics object container which can write itself out as a display list

OpenGL's display list functions can be tested. A gobjContainer can be written out as static geometry by a call to displaylistcreatenew(). This simplifies the use of display lists as the client only needs to create it and draw as any other gobj.

The example shows how parameter driven geometry like the glutWireTorus function need not be computed everytime but used to build variable geometry that is then compiled.

void test07::display

(

)

[virtual]

Derived classes define display.

Implements myglutgui.

Definition at line 34 of file test07.cpp.

References gobjContainer::draw(), and glerrordisplay().

{
  glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

  xGraphics.draw();

//cout << "drawing" << endl;
//cout << SHOW(xGraphics.vg.size()) << endl;

  glerrordisplay();
  glutSwapBuffers();
}

void test07::eval

(

)

[virtual]

Generally responsible for graphics initialization.

Not useful for classes with multiple initializations and hence this function is not abstract.

Reimplemented from myglutgui.

Definition at line 107 of file test07.cpp.

References gobjContainer::set().

{
  OpenGLinitialisation();
  
  glEnable(GL_DEPTH_TEST);
  glEnable(GL_CULL_FACE);

  //zpr::init();

  xGraphics.set();

  f1();

  glutPostRedisplay();
}

void test07::keyboard	(	unsigned char	key,
		int	x,
		int	y
	)			[virtual]

Derived classes define keyboard.

Reimplemented from myglutgui.
