John, I haven't had direct experience with DTK, but I've heard good things about it. I came _CLOSE_ to getting one, from my regular supplier, when I ordered my 286 board. When it arrived, it turned out to be an ELT, which he said was a little better. Anyhow, I…
OK, Joe. Looks like we do agree. Peace. Jack
#C to Pascal
Message #24444
"Because some people don't think like you do." Nice, Joe, very nice. Real friendly, too. It's been said that, to a man whose only tool is a hammer, every problem looks like a nail. I get that impression that to some folks, every problem looks like a job for malloc.…
Good question: why _ARE_ they so enamored of structures, pointers, and malloc. Granted, they are wonderful features and have their uses. But there's no law that says that you _HAVE_ to use chained pointers as the solution to every problem. Sometimes a good ol' static array works just as well,…
Mike, Bezier won't do what Aaron wants, since he wants a curve passing through specific intermediate points. Splines are the right answer. Jack
I don't know of such a routine on CIS, but see if you can get a copy of the book "Numerical Recipes in C." It has the spline fit that you're looking for. Jack

No, what I meant was: that convention center is very near the area of greatest damage in the last quake. BTW, I've been meaning to report to the folks over on CLM: The quake was detected by our inertial lab tiltmeters here in Clearwater, Fla. Remember, these are not seismometers,…
Well, I guess a "whole lot" is in the eye of the beholder, but to me 360K, which is the RAM required to digitize an Amiga screen, is a whole lot. Jack

If you have an exp and ln function (and don't mind the time it takes to use them) then the problem is much easier than you say: sqrt(x) = exp( ln(x) / 2.0). But then, if you have a language that has exp and ln, it also has sqrt! You…

#Three-Dee graphics
Message #34217
The classic way is the Newton iteration approach. Given a number A and an estimate R of its root, the next estimate is given by R' = 1/2 (R + A / R). You can use some kind of test on the difference, to decide when to quit, but it's…

John, not sure I got what you were saying but seems to me it's not as easy as you seemed to be saying. You said _EACH_ projected point. Does that mean each _PIXEL_??? If so, I agree that the approach is simple and works, but I also agree that'll take…

Jez: I also would use matrix math. I was trying to make it simple for Jeric. Too late, though … he's already slithered away in embarrassment, or something. Took a short course some years ago on Computer Graphics, and learned that all the hot dogs use a 4 x 4…

Modula-2
Message #13838
Oops! Pardon me! If you've been running on Pinnacle and Stride, I guess it was a real slap in the face to accuse you of being Mac-based. Anyhow, it's apparent that the compiler's been running on _SOMEBODY's_ 68K for long enough to get all the kinks worked out. The quality…

The answers to your questions are yes, yes, and yes. Address is: TDI Software, Inc. 10410 Markison Rd. Dallas, TX 75238 (214)-340-4941 Actually our number is (214) 340-4942. The 4941 number is for another building of the Pinnacle group that is located in back of us.

Les, got my copy Friday. Haven't had much time to get familiar with it (knowing Modula 2 would help!), but so far it's all you said it is. It's much faster than Lattice C. I must admit to being blown away with the quality of the compiler, and the degree…

There was a time when I would have thought Unix on an Amiga was the ultimate dumbness. Unix is an anachronism dating back to the days of 110-baud TTY's, while AmigaDOS has many elegant and modern design features. However, as I try to actually use AmigaDOS I'm rapidly coming around…

I don't think we have a problem, Steve. As I understand it, the user of a VAX doesn't have to concern himself with the VM mapping … that gets taken care of by the operating system. The discussion was: some people seem to have interpreted the fact that the Amiga…

OK, Russ, that explains a lot. Having come from the CP/M world (plus Multics, Unix and VMS), I was not aware that the mac required PC relative code. I hear you when you say PC-relative code is fast and small. I still say that it's a dumb restriction to place…

Scott, we certainly agree on one thing: the point _IS_ moot. I'm not sure the MMU has a lot to do with it. An MMU lets you map a large logical memory space onto a small physical space. Here we're just talking about putting program fragments into different addresses than…

We seem to be having a little semantics problem here, and I suspect it's the problem that's been permeating discussions of this subject everytime it comes up. That's why I brought it up this time. The semantics problem has to do with the term "relocatable code". As far back as…

Dave, I've heard this comment before, that you can't do absolute code on the Amiga. I don't claim to be an expert on the AMiga … I didn't get a developer's kit, so don't have all the facts, but I simply can't believe it's true. I realize that the Amiga…
