Open GL - Practical 7

Practical 7

Practical 7 is for us to learn how to create quadratic ojects such as cylinders and disk and also to creat lighting.

These are the shapes i came up with

Cylinder

Cylinder with lighting

Disk

Sample code for the cylinder:

glPushMatrix();
glTranslatef(0, 0, -20);
cylinder = gluNewQuadric();
glColor3ub(255,0,0);
gluCylinder(cylinder,5,5,30,32,32);//bigger
gluQuadricDrawStyle(cylinder, GLU_FILL);

glPushMatrix();
glTranslatef(0, 0, -20);
glColor3ub(0,0,255);
gluCylinder(cylinder,8,8,20,32,32);//bigger
gluQuadricDrawStyle(cylinder, GLU_FILL);
glPopMatrix();

glPushMatrix();
glTranslatef(0, 0, 20);
glColor3ub(0,255,0);
gluCylinder(cylinder,2,2,40,32,32);//bigger
gluQuadricDrawStyle(cylinder, GLU_FILL);
glPopMatrix();

glPopMatrix();
