Step 1. Make CUBE  .
Step 2. Set all cube and write //g 0
- //g 0 x^2 + y ^2 + z^2 +cos(4*x)+cos(4*y)+cos(4*z)-0.2 (Blobs)
- //g 0 x*x + y - z*z (HyperBolic)
- //g 0 x^2 + y^2 - z^2 -0.3 (HyperBoloid)
- //g 0 abs(x)+abs(y)+abs(z) - 1 (Octahedron)
- //g 0 x^4 + y^4 + z^4 - (x^2 + y^2 + z^2-0.3) (Chmutov)
- //g 0 2*(x^2*(3-4*x^2)^2+y^2*(3-4*y^2)^2+z^2*(3-4*z^2)^2) -3 (Chmutov2)
- //g 0 x^2 +y^2 -(1-z)*z^2 (DingDong)
- //g 0 ((x^2 + y^2 - 1)^2 + z^2)* ((y^2 + z^2 - 1)^2 + x^2)* ((z^2 + x^2 - 1)^2 + y^2) - 0.075^2 *(1 + 3* (x^2 + y^2 + z^2)) (OrthoCicle)
- //g 0 4*x^2*(x^2+y^2+z^2+z)+y^2*(y^2+z^2-1) (Leminescape)
