3D parametric plots - yes, we can.

[Nelson Sousa]

Hi all.

A while back there was some talk here about 3D parametric plots and
the fact that OS 3.0 doesn't allow them. Well, now it does ;) I
created a TNS file that plots up to three 3D parametric curves and
allows free rotation and graph trace.

Here's the link:
http://nelsonsousa.pt/index.php?lang=en&cat=2&subcat=3&article=61
As usual, it's available in both Portuguese and English.

It requires TI-Nspire 3.0 though, so if you didn't upgrade your
software/handheld, you'll have to wait until 3.0 is available again.

Next on my to do list: 3D parametric surfaces and 3D scatter plots. As
soon as I have enough time for it (which may or may not happen,
unfortunately).

Blatant and utterly unnecessary provocation: this is what happens when
one doesn't spend too much time complaining about what's missing on
the Nspire OS. May be slow, may be awkward, may be unnecessarily
complex. But it's definetely better than all other 3D parametric plot
tools for the Nspire available out there (which are, as far as I know,
non-existant; if you know of another one let me know, I'd like to test
it).

And it's not yet another port of Quake.

Have fun!
Nelson

What? No doc player??? Great work, Nelson!

Naaaa... I was going to until I read here that the doc player only
shows computer view and I optimized it for handheld view. :)

[Sean Bird]

Well done Nelson! I appreciate how it looks like it is in the default 3D environment.

[John Hanna]

It looks great in computer view, too, Nelson.

[Luke Setzer]

Nelson, I just want to thank you personally for all you do for this
group. You are a tremendous value to the advancement of the
technology. I know it can be a thankless job. So thank you. Your
contributions to the calculator community are, well, incalculable.

[Jimmy Fullerenex]

Can't agree with you more. In fact, Nelson's awesome website and downloads provided me with the very first inspiration on my journey with Nspire.

 

P.S. The only downside of this non-built-in plotter is that the "CPU-intensive" issue is quite serious on my hh. I still hope TI company can build the functionality into later OS. But right now, Nelson's creation serves as the best remedy (and inspiration), of course.

Cheers,

[Nelson Sousa]

Thanks all for your kind words.
Unfortunately I don't have much time to develop nowadays, so a lot of
projects are halted indefinetely :(

When OS 3.0 is out again I'll upgrade one of my handhelds and try to
improve performance, but I make no promises ;)

Cheers,
Nelson

[Jimmy Fullerenex]

Hi Nelson,

Just out of curiosity, will you buy the CX handhelds when they're available? Besides, is it true that the CX student software will be included in a single retail along with the hh?

Cheers,

Jimmy Fullerenex

2011/5/4 Nelson Sousa <nso...@gmail.com>

[Andy Kemp]

Yes, since 2.0 the student software has been included with the handheld.

[Nelson Sousa]

I don't think I'll buy the CX handheld. I'm not involved in teaching
or training anymore (TI-Nspire development is just a hobby), my
clickpad and touchpad are more than enough for my needs. I'll keep
updating the software though :)

Cheers,
Nelson

[lee kucera]

I have touchpad and clickpad units also, both CAS and Numeric, that I rarely use--preferring the software for ease of reading, etc. The CX resolution, backlighting, whatever, is so much better. I actually use my CX hh to try out tns file, etc. I put the teacher and student documents up on my laptop, load the file on my hh, and work through it. I never did that with the grayscale units. It is a vast improvement in visibility--especially for us with non-teenage eyes.

So Lee, you mean CX hh is already available? (the website never says anything other than "coming soon")

[Lana Golembeski]

no. He probably has a beta test calculator. We just have to wait!!

[Jimmy Fullerenex]

Oh yes. I wish I have a beta-testing version too! I can't wait for CX to come. ; )

[Lana Golembeski]

Me too! I have had the chance to work with one and they are awesome!

[Jimmy Fullerenex]

Gray scale is now coloured---- judging from the momentum of this giant leap, I feel for sure that TI will introduce Nspire touch-screen sooner or later. (since some of Casio calcs already do)

[Jimmy Fullerenex]

Lee: are you now still participating in devising newer OS?

If so, I wish TI math development team will incorporate more Statistical tools into later OS. (MANOVA; ANCOVA; non-parametric inference methods such as Mann-Whitney U, Wilcoxon signed-rank test, etc., should be present :-D) I'll probably choose to major in statistics. Nspire also lacks several important math functions(which seem to be present in Casio CAS), like gamma, zeta, beta functions and Laplace transformation.

I'll really appreciate it if you could propose my suggestion to the team. THX

Cheers,

It is my understanding that touch screen is under development and not too far out.  I overhead an ETC tell a good customer at T3 International that holding off on purchasing a class set of CS might be OK.  But any time line is a well guarded secret to which I am not privy.

[lee kucera]

Jimmy:

I'll be happy to pass your thoughts on.  TI has people monitoring this Nspire list so post your requests for statistics functions here.

lk

[Jimmy Fullerenex]

THX Lee. But what do you mean by  "TI has people monitoring this Nspire list so post your requests for statistics functions here."?

So TI officials also visit Nspire googlegroup and will actually adopt my suggestions here?

[Joe]

"So TI officials also visit Nspire googlegroup and will actually adopt
my suggestions here?"

No, not exactly Jimmy. People have been asking ti to add the missing
functionality that other calcs have, like the missing Laplace
capability that you mention, since nspire was introduced about 4 years
ago but ti has ignored those requests. It is not clear, at least not
to me, why ti doesn't feel that their product has to be mathematically
competitive.

Huge distortion of facts there Joe, even for you.

Yes, there are people at TI that read (and sometimes reply) to
messages posted here.
Yes, TI has implemented features that were first suggested here (or
were suggested here as well as in other places).

And yes, despite Joe asking for Laplace transforms since pre-historic
ages, it wasn't implemented on the Nspire CAS so far. What this means
is that opinions expressed here are taken into account. They may or
may not be implemented, I don't know which criteria are behind such
decision (and therefore, I don't try to guess).

[Joe]

Nice job on that program to plot 3d curves Nelson. To come out with
that so quickly was awesome.

[Nelson Sousa]

Thanks.

It's not as much a matter of complexity or effort, but more of having
the right ideas to solve a specific problem.

Cheers,
Nelson

[Jimmy Fullerenex]

Hi Nelson, have you ever worked with Lua? if your 3D curve plotter is written in Lua, I'm sure it'll function much quicker (and more awesome) (I understand you're really busy... but this can well be a possibility for future consideration ;-) )
