Code Box Test

Just found this which might help writing blocks of code in my posts...

Let's see;

#include "allegro5/allegro.h"
#include "allegro5/allegro_opengl.h"
#include "allegro5/allegro_image.h"
#include "GL/glu.h"


int main()
{
 ALLEGRO_DISPLAY *display = NULL;
 ALLEGRO_BITMAP *bmp = NULL;

 GLuint ogl_tex; // The OpenGL texture id.

 al_init();
 al_init_image_addon();

 al_set_new_display_flags(ALLEGRO_OPENGL);
 display = al_create_display(800, 600);

 // Load a bitmap to use as a texture
 bmp = al_load_bitmap("texture.jpg"); // 256 x 256 pixels
 ogl_tex = al_get_opengl_texture(bmp);

 glMatrixMode(GL_PROJECTION);
 glLoadIdentity();
 gluPerspective(35.0, 800.0 / 600.0, 1.0, 400.0);

 glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

 glMatrixMode(GL_MODELVIEW);
 glLoadIdentity();
 glTranslatef(0.0f, 0.0f, -15.0f);

 glEnable(GL_DEPTH_TEST);

 glEnable(GL_TEXTURE_2D);
 glBindTexture(GL_TEXTURE_2D, ogl_tex);

 glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
 glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);

 glBegin(GL_QUADS);

 glNormal3f(0.0, 0.0, 1.0);

 glTexCoord2f(0.0, 0.0); // Bottom left hand corner
 glVertex3f(-1.5, -1.5, 0.0); // X,Y,Z
 glTexCoord2f(2.0, 0.0); // Bottom right hand corner
 glVertex3f(1.5, -1.5, 0.0); // X,Y,Z
 glTexCoord2f(2.0, 2.0); // Top right hand corner
 glVertex3f(1.5, 1.5, 0.0); // X,Y,Z
 glTexCoord2f(0.0, 2.0); // Top left hand corner
 glVertex3f(-1.5, 1.5, 0.0); // X,Y,Z

 glEnd();

 glDisable(GL_TEXTURE_2D);
 glDisable(GL_DEPTH_TEST);

 al_flip_display();

 al_rest(10.0);

 glDeleteTextures(1, &ogl_tex);
 al_destroy_bitmap(bmp);
 al_destroy_display(display);
 return 0;
}

How does that look?

Yeah, not too bad. I am learning something about blogging, after all. I'll use that from now on. The font size is 80%.

As for the listing in the test example, well, that will be the subject of my next series of posts here.
