abecedarian 330 Posted November 28, 2012 Share Posted November 28, 2012 I know I've "proposed" some projects in the forums, and I've come to realize that pretty much a ALL of that is over my head. Blinking lights at a Dragon's breath, using someone else's code isn't exactly something to rejoice over. Granted, it looks cool and I may be even able to claim a bit of pride since I did tweak the code a little for some added drama, but that is just added drama, and it isn't getting me closer to the RFID car security system, simulating an engine... or even fuel injection. I find myself playing more with the variables than trying something new. I'm having issues making the jump from "this" to "that", so, I'm hoping someone with a good grasp on things may be willing to waste a bit of thought with me. Mind you, nearly everyone here seems to have few issues moving back and forth between architecture or capability, primarily because "you" have a grasp on it. Back in the day, I may have animated the MCP (from Tron, and it sucked and was a hobby) and such, but an Apple computer is a bit different than what I'm looking at. I see the benefits of doing things like LED cubes and such- they are "cubes' and all the math and such fits in to shift registers and like. I've 50 74HC595 shift registers on order (sucker changed my bid from $1 for 5 to $10 for 50, but it's okay: I can afford it, and I'll dispense a few if anyone needs). I bought them because my nephew and a few others like the cube displays, and those are easy-enough to build... though it also means I need to buy more MSP's. >sigh< However, a cube is a nice ^2 thing, no matter which way you slice it, so it makes sense using shift registers: shift bits and instantly things change to the next line, row, column.... But, what caught my eye, was why there aren't any pyramids or any other complex shapes out there. I mean, other than the spinning LED's for POV and such, it's 3x3x3, 4x4x4, 8x8x8 et cerebral. I immediately realized it was because the "math" doesn't work well with shapes whose sides are not a derivative from ^2. It's not fluid, per se. Though one could map a 5x5 array to a solid pyramid with 25 LED's: 12 on the base, 8 at the next level, 4 at the next and one at the top, 5^2=25, being a "square", doesn't permit simple bit shifting to work since the geometry isn't "square" or "cubed". That immediately presents issues for animation. Another thing I thought of about was pulling and squishing a proper cube in to a "diamond"-like shape, but then it would only be regular cube, pulled and squished. So, maybe someone pushing me would be helpful. And given the thoughts I presented above, that may push someone else to help me? So, if interested, PM me, and we'll start the discussions. Otherwise, just reply here and we'll see where it goes. Quote Link to post Share on other sites
