[Q] Surface tessellation bounding the original surface?

[Young J. Kim]

Dear comp geometers:

Is there anybody who has heard about a surface tessellation method that
bounds the given, parametric surface? In other words, the given surface
should be always enclosed inside the tessellation. Moreover, my surface
can include non-rational terms including trigonometric functions.

I will appreciate it if somebody can tell me any pointers to earlier
work on this issue.

Thanks in advance.

Young.
