示例1: setViewport
/* function to reset our viewport after a window resize
*/
int setViewport(int width, int height)
{
/* Height / width ration */
GLfloat ratio;
/* Protect against a divide by zero */
if (height == 0) height = 1;
ratio = (GLfloat)width / (GLfloat)height;
/* Setup our viewport. */
GL(glViewport, (0, 0, (GLsizei)width, (GLsizei)height));
/* change to the projection matrix and set our viewing volume. */
GL(glMatrixMode, (GL_PROJECTION));
GL(glLoadIdentity, ());
/* Set our perspective */
//GL(gluPerspective, (45.0f, ratio, 0.1f, 100.0f));
GL(glOrtho, (0, (GLdouble)width, 0, (GLdouble)height, -1, 1));
/* Make sure we're chaning the model view and not the projection */
GL(glMatrixMode, (GL_MODELVIEW));
/* Reset The View */
GL(glLoadIdentity, ());
text_renderer.setViewportSize(width, height);
return 1;
