Looking for a high accuracy 3D graphing program

[Tegewaldt]

Hi PF/math !

I've been searching for a program which will draw 3d parametric curves accurately for large variables, eg. f(10^8).
Ive tried www.math.uri.edu and Ti-Nspire (the latter may or may not have a setting for the accuracy), but both tend to turn what should've been a smooth curve into an angled nightmare.

If anyone knows a decent program or how to fix the thing in Ti-Nspire, please let me know!

Thank you for your time and help

I use pocketCAS on the iPad and it seems to generate pretty smooth curves.

Can you tell us what surface you're trying to plot?

i'ts not a surface, it's a parametric curve. 3 independent functions, one for each dimension.
