It's more accurate. I probably will add these animations to the Wiki.

P.S. Some men told me that they don't understand what are those red lines. I suppose it's obviously for me only that these are the same torus that is included in this tiger. Tiger in these three animations is the same, but it's rotated at different angles.

And now I need to know how to make those http://hi.gher.space/dl/EEWRMK20J64PJM8K47DT05W9V1.png cross-sections using a parametric surface (that consist of X equation, Y equation and Z equation with u, v parameters)

I made the third variant of cross-sections and net of a cubinder. Is it more felicitous than previous ones?

P.S. According to some people, I understood that these net and cross-sections are not clear and obvious for beginners. The first variant of these ones (with red and blue lines only) they liked more. I think that I should make one more variant.

Slices of a spheritorus. Сompare these ones with the cross-sections of a tiger.

P.S. The red lines on these animations are the same sphere that is included in the same spheritorus which is rotated at different angles.

Cross-sections of a torisphere.

P.S. The red lines are the same torus that is included in this torisphere.

Slices of a ditorus.

P.S. I think it's clear that the red lines are the same torus that is included in this ditorus.
