示例1: display
//glut display function
void display(void)
{
glClear(GL_COLOR_BUFFER_BIT);
// Draw all the points
glColor3f(1.0, 0.0, 0.0);
for (int x=0; x<numPoints; x++)
polyPoint[x].draw();
// Draw the polgon
if (initializeComplete)
{
glColor3f(0.0, 0.0, 1.0);
glBegin(GL_LINE_LOOP);
for (int x=0; x<numPoints; x++)
glVertex2f(polyPoint[x].getX(), polyPoint[x].getY());
glEnd();
}
// Draw the test point, and the text saying whether it's inside or outside.
if (firstPointDrawn)
{
char inside[] = "The point drawn is INSIDE the polygon.";
char outside[] = "The point drawn is OUTSIDE the polygon.";
glColor3f(0.0, 1.0, 0.0);
