程序：void CMyWaveView::DrawWave(void)
{

glNewList (listName, GL_COMPILE_AND_EXECUTE); GLfloat x;
glBegin(GL_LINE_STRIP);
glColor3f(0.0,0.0,0.0);
for(x=-1.0f; x<=-0.875f; x+=0.001f)
{
glVertex2f(x,/* random()**/0.5*sin(8.0*Pi*x));
}
glEnd();

glBegin(GL_LINES);
glVertex2f(-0.875f,0.2*sin(4*Pi*(-0.75f)));
glVertex2f(-0.70,0.1f/*0.4*sin((double)4*Pi*(-0.75f))*/);
glEnd();

glBegin(GL_LINES);
glVertex2f(-0.70f,0.1f/*0.5*sin((double)4*Pi*(-0.75f))*/);
glVertex2f(-0.65f,0.2*sin(4*Pi*(-0.75f)));
glEnd();

glBegin(GL_LINES);
glVertex2f(-0.65f,0.2*sin(4*Pi*(-0.75f)));
glVertex2f(-0.60,0.1f/*0.4*sin((double)4*Pi*(-0.75f))*/);
glEnd();

glBegin(GL_LINES);
glVertex2f(-0.60f,0.1f/*0.5*sin((double)4*Pi*(-0.75f))*/);
glVertex2f(-0.55f,
