Looking for a high accuracy 3D graphing program

Click For Summary

Discussion Overview

The discussion centers on finding a high-accuracy program for drawing 3D parametric curves, particularly for large variable inputs. Participants share their experiences with different software and seek recommendations for alternatives or solutions to issues encountered.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses frustration with existing programs, specifically mentioning issues with accuracy in rendering smooth curves in Ti-Nspire and another online tool.
  • Another participant suggests using pocketCAS on the iPad, claiming it generates smooth curves, and inquires about the specific surface the original poster is trying to plot.
  • A clarification is provided that the focus is on a parametric curve defined by three independent functions, rather than a surface.
  • A different participant recommends SciLab as a free alternative to MatLab, expressing satisfaction with its capabilities.

Areas of Agreement / Disagreement

Participants have not reached a consensus on a single recommended program, and multiple software options are being discussed without agreement on their effectiveness for the specific needs outlined.

Contextual Notes

There is a lack of detailed information on the specific requirements for accuracy and the nature of the parametric curves being plotted, which may affect the suitability of the suggested programs.

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.

SciLab? It's like MatLab... but it's free. I love SciLab...
