引用一下
#!/usr/local/bin/perl -w
use strict;
use OpenGL qw(:all :old);
require "OpenGLTools.pl";
sub triangle
{
glBegin (GL_TRIANGLES);
glColor3f (0.0, 0.0, 0.0);
glVertex2f(0.0, 0.0);
glColor3f (0.5, 0.5, 0.5);
glVertex2f(30.0, 0.0);
glColor3f (1.0, 1.0, 1.0);
glVertex2f(0.0, 30.0);
glEnd ();
}
glpOpenWindow (width => 250, height => 250);
glLoadIdentity();
gluOrtho2D (0.0, 30.0, 0.0, 30.0);
glClearColor (1.0, 1.0, 1.0, 0.0);
glClear (GL_COLOR_BUFFER_BIT);
triangle();
gltIMCapture("OpenGLcap1.png", 50, 50, 100, 100);
gltIMCapture("OpenGLcap2.png");
This is a basic OpenGL application that draws a triangle, filled with a smooth grayscale
gradient. Once the drawing is finished, it captures part of the window, and the
whole window with the previously discussed gltIMCapture() function, and saves
these captures to files which can be seen in figure 9.1.
