TI Calculators / Re: Is it possible to run a TI-84+ OS on a TI-84+CSE?
« on: January 26, 2014, 07:55:41 pm »
I wouldn't call it greedy so much as doing business. They know the customer is willing to pay these prices for outdated hardware because of their near-monopoly in schools, so they can get away with it. Yes, the cost of production might not be much higher to add more flash memory, but like any sensible business, they set their prices to make the most profit. We will only see change if there is more significant competition from other companies.

You don't need a CSE (It won't work at all on it), just an 84+ SE. (Or if you would like to be the first one to try it, an 83+ SE.)

Casio Calculators / Re: [C] Minesweeper

I don't know much about Casio hardware, but would it be possible to add grayscale? It would look a lot better than the dithering in those unrevealed tiles.

I was in middle school when I joined. Needless to say, I posted like one back then. :P Anyways, I think we need to give the new users a chance. They will no doubt make mistakes, but we should politely point them out/correct them instead of responding with hostility, and they will soon pick up on proper forum etiquette.

I actually use IE11 sometimes, since Youtube upload is broken in Chrome/Opera/Firefox/Safari it seems, and some sites are IE-only. However, it's slow-ish D:
IE isn't that bad performance-wise nowadays. It also has low memory usage, so I find it useful when I'm on a machine with only 2GB of RAM. Otherwise, I just use Firefox because it has extensions.

Axe / Re: [Axe] Plane deformations are fun

If you need help wrapping your head around Mode 7, just ask. None of the explanations I found on the internet made sense to me, so I struggled with it for a while.

That's what I initially used for my Nspire Mode 7 engine, but I moved on to faster methods. For the mode 7-type plane, the derivative of the coordinates between pixels on the same row of the screen is constant, so you can just add a constant vector to the coordinates for a pixel to get the coordinates for the next. It's not as easy when you get into using trig functions, but you could keep the values of sine and cosine, and add them to each other to quickly and dynamically compute their values, though this probably won't work out so well with the limited precision you have.

Forum Arcade Games / Re: Final Omni Arcade highscores (top 3)
« on: January 23, 2014, 12:52:33 am »
To make it unique, games for a new arcade could be written in TI-BASIC and run in a JavaScript interpreter.

Shifting left always inserts zeros, while rotating left inserts the same bit that was removed on the other side.

And you can expect to see big improvements in the Linux driver now that there are Steamboxes.

Changed some things around and now only one timer is used, removing the overhead from the interrupt checking which timer was triggered. Because of this, I can run the interrupt slightly faster, hopefully pushing the high pitched noise out of the range of hearing for some more people. I also halved the frequency of one channel, allowing for the more of the lower pitched notes used in the original version of the arrangement I was given.

TI-Nspire / Re: nGL - a fast (enough) 3D engine for the nspire

Sorry, I meant raycasting for block picking. Not for rendering. :P

Definitely raycasting. Since everything is cubes, digital differential analysis will be perfect.

calc84maniac, I finally implemented that suggestion you made to me on IRC a while back, with accumulating an error based on the fractional part of the period of the tone, and using that to toggle between two values of the period. It sounds much better in tune now.
