We often focus on calculator games, disasters, hardware, programming and discoveries-oriented news here, but it is always positive news when great educational tools makes it to newly-released calculator models, as most people buy calcs for school, after all.

Tonight is the case, as 3D graphing arrives on the TI-84 Plus C Silver Edition!

Back in 2003, KermMartian released Graph3D, a TI-BASIC 3D grapher, which he updated over the years. Tonight, 84+CSE users will now be able to experience it in color, with Graph 3D v4.1 Color 3D Grapher! You can basically use it like any other calculator 3D grapher, without having to buy another calc like the expensive TI-89 or the TI-Nspire CX. Of course the speed might not be as fast as on higher-end calculator models, but it still seems to do the job pretty well and this version even features some speed improvements over the past version, as the news attached above reports.

This tool comes 1 year after Graph3DP 1.0 for the Casio PRIZM came out, meaning that every color-screen calculator model now has its own 3D grapher, two being courtesy of Cemetech, where you can report any bug or feature suggestions if any!

Thanks for the article, DJ_O. Graph3DP actually helped me make this version, as the 3D rotation code I spend weeks hashing out for Graph3DP found its way into this new program. I was able to apply it to the entire lists of X, Y, and Z coordinates at once, eliminating the need to iterate to rotate points and contributing to the significant speedup over the old version.

To my surprise, Pt-On/Off and very small lines were really fast on the 84+CSE (I tried displaying sprites using them), so that alone probably won't impact speed much for a 3D Grapher. The speed gain is most likely from BASIC maths, right?

Kerm is awesome!  Although I don't plan on getting an 84PCSE I'm sure the people that are sure appreciate it.

The way that you guys talk, I wouldn't be surprised if you could write an optimized TIOS lol

Hasn't TIOS 1.19 been completely disassembled? In such a way that people could grab the computer generated source and modify it?

Even if people could, it would then be illegal to distribute the modified OS, so I guess nobody really bothers doing so. But if you want a better OS, try thepegenguin's patch (check his signature). They allow you to archive faster, etc... And zStart (still by thepenguin77) is awesome too, letting you run program even if they are archived (you'll say "a lot of shells do that") and reinstalling itself by itself after a RAM Clear (you'll say "ah" ).

I'm quite familiar with both. I just wish Ti-Basic were faster or math was..
Oh, I'm still wondering if anyone knows enough about the Basic interpreter oncalc to see if they can write a Basic compiler

BASIC is interpreted tho...
Anyway, this looks like a nice prog! If I get a CSE this will be on it.

ik, but interpreted languages can be compiled if you write a compiler for it
