As the title says, the cube isn't rendered correctly (you see these holes?)
Here is the code:
GL11.glMatrixMode(GL11.GL_PROJECTION);
GL11.glLoadIdentity();
GL11.glOrtho(-5, 5, -5, 5, -1, 5);
GL11.glMatrixMode(GL11.GL_MODELVIEW);
float x = 0;
while (!Display.isCloseRequested())
{
Display.update();
GL11.glClear(GL11.GL_DEPTH_BUFFER_BIT|GL11.GL_COLOR_BUFFER_BIT);
GL11.glEnable(GL11.GL_DEPTH_TEST);
GL11.glColor3f(1, 0, 0);
GL11.glRotatef(x+=0.01f, 1, 1, 1);
GL11.glBegin(GL11.GL_QUADS);
GL11.glColor3f(0.0f,1.0f,0.0f); // Set The Color To Green
GL11.glVertex3f( 1.0f, 1.0f,-1.0f); // Top Right Of The Quad (Top)
GL11.glVertex3f(-1.0f, 1.0f,-1.0f); // Top Left Of The Quad (Top)
GL11.glVertex3f(-1.0f, 1.0f, 1.0f); // Bottom Left Of The Quad (Top)
GL11.glVertex3f( 1.0f, 1.0f, 1.0f); // Bottom Right Of The Quad (Top)
GL11.glColor3f(1.0f,0.5f,0.0f); // Set The Color To Orange
GL11.glVertex3f( 1.0f,-1.0f, 1.0f); // Top Right Of The Quad (Bottom)
GL11.glVertex3f(-1.0f,-1.0f, 1.0f); // Top Left Of The Quad (Bottom)
GL11.glVertex3f(-1.0f,-1.0f,-1.0f); // Bottom Left Of The Quad (Bottom)
GL11.glVertex3f( 1.0f,-1.0f,-1.0f); // Bottom Right Of The Quad (Bottom)
GL11.glColor3f(1.0f,0.0f,0.0f); // Set The Color To Red
GL11.glVertex3f( 1.0f, 1.0f, 1.0f); // Top Right Of The Quad (Front)
GL11.glVertex3f(-1.0f, 1.0f, 1.0f); // Top Left Of The Quad (Front)
GL11.glVertex3f(-1.0f,-1.0f, 1.0f); // Bottom Left Of The Quad (Front)
GL11.glVertex3f( 1.0f,-1.0f, 1.0f); // Bottom Right Of The Quad (Front)
GL11.glColor3f(1.0f,1.0f,0.0f); // Set The Color To Yellow
GL11.glVertex3f( 1.0f,-1.0f,-1.0f); // Bottom Left Of The Quad (Back)
GL11.glVertex3f(-1.0f,-1.0f,-1.0f); // Bottom Right Of The Quad (Back)
GL11.glVertex3f(-1.0f, 1.0f,-1.0f); // Top Right Of The Quad (Back)
GL11.glVertex3f( 1.0f, 1.0f,-1.0f); // Top Left Of The Quad (Back)
GL11.glColor3f(0.0f,0.0f,1.0f); // Set The Color To Blue
GL11.glVertex3f(-1.0f, 1.0f, 1.0f); // Top Right Of The Quad (Left)
GL11.glVertex3f(-1.0f, 1.0f,-1.0f); // Top Left Of The Quad (Left)
GL11.glVertex3f(-1.0f,-1.0f,-1.0f); // Bottom Left Of The Quad (Left)
GL11.glVertex3f(-1.0f,-1.0f, 1.0f); // Bottom Right Of The Quad (Left)
GL11.glColor3f(1.0f,0.0f,1.0f); // Set The Color To Violet
GL11.glVertex3f( 1.0f, 1.0f,-1.0f); // Top Right Of The Quad (Right)

GL11.glVertex3f( 1.0f,-1.0f, 1.0f); // Bottom Left Of The Quad (Right)
GL11.glVertex3f( 1.0f,-1.0f,-1.0f); // Bottom Right Of The Quad (Right)
GL11.glEnd();
GL11.glLoadIdentity();
}
That is viewport clipping. Your view is too close to the cube so anything outside the viewing volume (in this case behind the camera) gets clipped. Set the near value in glOrtho to -2 or -3 instead.
Ah ok thanks ;D
