    <p>I have written the following program to display a teapot on a table in a room with 2side walls and a floor.</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;glut.h&gt; void wall1(float thickness) { glPushMatrix(); glTranslatef(100,100,0); glRotatef(90,1,0,0); glScalef(thickness,1,1); glutSolidCube(100); glPopMatrix(); } void wall2(float thickness) { glPushMatrix(); glTranslatef(150,100,-50); glScalef(1,1,thickness); glutSolidCube(100); glPopMatrix(); } void floor(float thickness) { glPushMatrix(); glTranslatef(150,50,0); glScalef(1,thickness,1); glutSolidCube(100); glPopMatrix(); } void leg(float thickness) { glPushMatrix(); glScalef(thickness,.5,thickness); glutSolidCube(100); glPopMatrix(); } void tableTop(float thickess) { glPushMatrix(); glTranslatef(150,100,0); glScalef(.5,thickess,.5); glutSolidCube(100); glPopMatrix(); } void table() { tableTop(.05); glPushMatrix(); glTranslatef(125,75,-25); leg(.05); glPopMatrix(); glPushMatrix(); glTranslatef(175,75,-25); leg(.05); glPopMatrix(); glPushMatrix(); glTranslatef(175,75,25); leg(.05); glPopMatrix(); glPushMatrix(); glTranslatef(125,75,25); leg(.05); glPopMatrix(); glPushMatrix(); glTranslatef(150,110,0); glScalef(.1,.1,.1); glutSolidTeapot(100); glPopMatrix(); } void display() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); float pos[] = {200,200,0}; float dif[] = {.3,.3,.3,3}; float spe[] = {1,1,1,1}; float amb[] = {1,1,1,0}; glLightfv(GL_LIGHT0,GL_POSITION,pos); glLightfv(GL_LIGHT0,GL_DIFFUSE,dif); glLightfv(GL_LIGHT0,GL_AMBIENT,amb); glLightfv(GL_LIGHT0,GL_SPECULAR,spe); glTranslatef(50,50,0); glRotatef(30,1,0,0); glRotatef(-30,0,1,0); wall1(.05); wall2(.05); floor(0.05); table(); glFlush(); } void reshape(int w,int h) { glViewport(0,0,w,h); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(0,400,0,400,-400,400); glMatrixMode(GL_MODELVIEW); } void main(int argc,char** argv) { glutInit(&amp;argc,argv); glutInitDisplayMode(GLUT_RGB | GLUT_SINGLE | GLUT_DEPTH); glutInitWindowPosition(100,100); glutInitWindowSize(400,400); glutCreateWindow("woot"); glClearColor(1,1,1,1); glEnable(GL_DEPTH_TEST); glEnable(GL_LIGHTING); glEnable(GL_LIGHT0); glShadeModel(GL_SMOOTH); glutReshapeFunc(reshape); glutDisplayFunc(display); glutMainLoop(); } </code></pre> <p>The problem with this is my lighting part is not working as expected. Its not illuminating <strong>evenly</strong> all my objects... What am i missing? This making even the teapot hard to sea. My lighting part is in display function.</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
