Opegl Cube (Blank Screen)

Allright so after failing at rotating my own cube i decided to go with a cube tutorial to see if it was the problem and

I found this code on NeHe’s site but it doesnt work…

glMatrixMode(GL_MODELVIEW);
 glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
 glPushMatrix();
 glOrtho(0,600,400,0,-1,1);
 
 
 glBegin(GL_QUADS);                  // Start Drawing The Cube
 glTranslatef(1.5f,0.0f,-7.0f);  
 glColor3f(0.0f,1.0f,0.0f);          // Set The Color To Green
 glVertex3f( 1.0f, 1.0f,-1.0f);          // Top Right Of The Quad (Top)
 glVertex3f(-1.0f, 1.0f,-1.0f);          // Top Left Of The Quad (Top)
 glVertex3f(-1.0f, 1.0f, 1.0f);          // Bottom Left Of The Quad (Top)
 glVertex3f( 1.0f, 1.0f, 1.0f);          // Bottom Right Of The Quad (Top)

 glColor3f(1.0f,0.5f,0.0f);          // Set The Color To Orange
 glVertex3f( 1.0f,-1.0f, 1.0f);          // Top Right Of The Quad (Bottom)
 glVertex3f(-1.0f,-1.0f, 1.0f);          // Top Left Of The Quad (Bottom)
 glVertex3f(-1.0f,-1.0f,-1.0f);          // Bottom Left Of The Quad (Bottom)
 glVertex3f( 1.0f,-1.0f,-1.0f);          // Bottom Right Of The Quad (Bottom)

 glColor3f(1.0f,0.0f,0.0f);          // Set The Color To Red
 glVertex3f( 1.0f, 1.0f, 1.0f);          // Top Right Of The Quad (Front)
 glVertex3f(-1.0f, 1.0f, 1.0f);          // Top Left Of The Quad (Front)
 glVertex3f(-1.0f,-1.0f, 1.0f);          // Bottom Left Of The Quad (Front)
 glVertex3f( 1.0f,-1.0f, 1.0f);          // Bottom Right Of The Quad (Front)


 glColor3f(1.0f,1.0f,0.0f);          // Set The Color To Yellow
 glVertex3f( 1.0f,-1.0f,-1.0f);          // Bottom Left Of The Quad (Back)
 glVertex3f(-1.0f,-1.0f,-1.0f);          // Bottom Right Of The Quad (Back)
 glVertex3f(-1.0f, 1.0f,-1.0f);          // Top Right Of The Quad (Back)
 glVertex3f( 1.0f, 1.0f,-1.0f);          // Top Left Of The Quad (Back)

 glColor3f(0.0f,0.0f,1.0f);          // Set The Color To Blue
 glVertex3f(-1.0f, 1.0f, 1.0f);          // Top Right Of The Quad (Left)
 glVertex3f(-1.0f, 1.0f,-1.0f);          // Top Left Of The Quad (Left)
 glVertex3f(-1.0f,-1.0f,-1.0f);          // Bottom Left Of The Quad (Left)
 glVertex3f(-1.0f,-1.0f, 1.0f);          // Bottom Right Of The Quad (Left) 
 
 glColor3f(1.0f,0.0f,1.0f);          // Set The Color To Violet
 glVertex3f( 1.0f, 1.0f,-1.0f);          // Top Right Of The Quad (Right)
 glVertex3f( 1.0f, 1.0f, 1.0f);          // Top Left Of The Quad (Right)
 glVertex3f( 1.0f,-1.0f, 1.0f);          // Bottom Left Of The Quad (Right)
 glVertex3f( 1.0f,-1.0f,-1.0f);          // Bottom Right Of The Quad (Right)

I cant see anything IDK if it too small and why every tutorial about this make’s it invisible but

IDK how to correct this values without messing the cube

*Sigh…

Sometimes its very frustrating

OH i must add Quite not have same setup cause im using SDL for screen and events…

NVM Solved few… it was very thought
