  10. void CChildView::OnGLDraw(CDC *pDC) { glClearColor(0.0f, 0.0f, 0.0f, 0.0f) ; glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); // Set up the camera glMatrixMode(GL_PROJECTION); glLoadIdentity(); // Determine the screen size so we can determine the aspect ratio int width, height; GetSize(width, height); // Set the camera parameters gluPerspective(25., // Vertical field of view in degrees. GLdouble(width) / GLdouble(height), // The aspect ratio. 10., // Near clipping 200.); // Far clipping // Set the camera location glMatrixMode(GL_MODELVIEW); glLoadIdentity(); gluLookAt(20., 10., 50., // eye x,y,z 0., 0., 0., // center x,y,z 0., 1., 0.); // Up direction

  11. // Enable depth test glEnable(GL_DEPTH_TEST); // Cull backfacing polygons glCullFace(GL_BACK); glEnable(GL_CULL_FACE); // Enable lighting glEnable(GL_LIGHTING); glEnable(GL_LIGHT0); GLfloat lightpos[] = {.5, 1, 1, 0.}; // GLfloat lightpos[] = {10., 10., 10., 1.}; glLightfv(GL_LIGHT0, GL_POSITION, lightpos);

  12. glPushMatrix(); GLfloat white[] = {0.8f, 0.8f, 0.8f, 1.0f}; GLfloat cyan[] = {0.f, .8f, .8f, 1.f}; glMaterialfv(GL_FRONT, GL_DIFFUSE, cyan); glMaterialfv(GL_FRONT, GL_SPECULAR, white); GLfloat shininess[] = {100}; glMaterialfv(GL_FRONT, GL_SHININESS, shininess); glRotated(m_spinangle, 1, .5, .7); Box(5, 5, 5); glPopMatrix(); glFlush();

  13. void CChildView::Box(GLdouble p_x, GLdouble p_y, GLdouble p_z) { GLdouble a[] = {0., 0., p_z}; GLdouble e[] = {0., 0., 0.}; GLdouble b[] = {p_x, 0., p_z}; GLdouble f[] = {p_x, 0., 0.}; GLdouble c[] = {p_x, p_y, p_z}; GLdouble g[] = {p_x, p_y, 0.}; GLdouble d[] = {0., p_y, p_z}; GLdouble h[] = {0., p_y, 0.}; // Front glBegin(GL_QUADS); glNormal3d(0, 0, 1); glVertex3dv(a); glVertex3dv(b); glVertex3dv(c); glVertex3dv(d); glEnd(); // Right glBegin(GL_QUADS); glNormal3d(1, 0, 0); glVertex3dv(c); glVertex3dv(b); glVertex3dv(f); glVertex3dv(g); glEnd();
