    <p>i really want to draw a cube with balls bouncing on the walls of the cube but i can not get any further than this code below which is just a cube rotating im a newbie and i just started learning about opengl last week,if somebody can help me with the required info i will greatly appreciate,i want the ball to be bouncing upside down without them touching each other and thier radius should be the same</p> <pre><code>#include &lt;GL\glut.h&gt; GLfloat xRotated, yRotated, zRotated; void init(void) { glClearColor(0,0,0,0); } void DrawCube(void) { glMatrixMode(GL_MODELVIEW); // clear the drawing buffer. glClear(GL_COLOR_BUFFER_BIT); glLoadIdentity(); glTranslatef(0.0,0.0,-10.5); glRotatef(xRotated,1.0,0.0,0.0); // rotation about Y axis glRotatef(yRotated,0.0,1.0,0.0); // rotation about Z axis glRotatef(zRotated,0.0,0.0,1.0); glBegin(GL_QUADS); // Draw The Cube Using quads glColor3f(0.0f,1.0f,0.0f); // Color Blue 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); // Color 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); // Color 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); // Color Yellow 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) 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) glColor3f(0.0f,0.0f,1.0f); // Color 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); // Color 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) glEnd(); // End Drawing The Cube glFlush(); } void animation(void) { yRotated += 0.01; xRotated += 0.02; DrawCube(); } void reshape(int x, int y) { if (y == 0 || x == 0) return; //Nothing is visible then, so return //Set a new projection matrix glMatrixMode(GL_PROJECTION); glLoadIdentity(); //Angle of view:40 degrees //Near clipping plane distance: 0.5 //Far clipping plane distance: 20.0 gluPerspective(40.0,(GLdouble)x/(GLdouble)y,0.5,20.0); glMatrixMode(GL_MODELVIEW); glViewport(0,0,x,y); //Use the whole window for rendering } int main(int argc, char** argv){ glutInit(&amp;argc, argv); //we initizlilze the glut. functions glutInitDisplayMode(GLUT_SINGLE|GLUT_RGB); glutInitWindowPosition(100, 100); glutCreateWindow(argv[0]); init(); glutDisplayFunc(DrawCube); glutReshapeFunc(reshape); //Set the function for the animation. glutIdleFunc(animation); glutMainLoop(); return 0; } </code></pre>

    1. COStackOverflow is not intended for "tell me how to write my entire program"-type questions. Just keep learning with the help of tutorials and/or some books - there's a lot of material available about OpenGL. While you do so you might want to ditch immediate mode, since it's [obsolete](http://www.opengl.org/wiki/Legacy_OpenGL).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
