sphere.c

gcc -o sphere sphere.c

./sphere

All except following features are same as the donut.

1. I made a sphere of radius R from the point (RS, RS, 0). Refer to sphere.c for variable descriptions.
2. Then I rotated the sphere about x-axis and z-axis.
3. Each coordinate (x, y, z) is obtained by the parametric equation of sphere * parallel translation matrix * rotation matrix.
