3D Graphing Package, Microsoft Mathematics
-
First glance, gorgeous. Will it allow me to export a nice JPEG or PNG file ?
-
Second glance; uh-oh, learning curve, big time. I want to plug in my Z = f(x,y) equation (which is a bit complex) press a button and see the graph ready for my use. The equation has sums, differences, two levels of division operations, a max, a min, and an abs function vicariously scattered within those operations. Can Octave take an equation and derive the 3D graph with the push of a button ?

I'm trying to get a 3D graph prepared. I just wasted two days on this app, Graphing Calculator 3D[^] but the author decided on some sort of copy protection or cripple ware or whatever you want to call it. i.e., It makes an excellent graph of Z = f(x,y) but then you can't use that image; e.g., no JPEG, no PNG, in fact, you can't even do a screen print. My motto is: Just say no to any and all such apps. So I came across an app from Microsoft, Mathematics 4.0[^] Before I go wasting another two days on a freeware app that isn't free, can anyone tell me if Microsoft Mathematics will... -1- Generate a good looking graph, Z = f(x,y) -2- Save that image in a file for use by other apps
I remember a similar problem with a graphics app some years back (Xera? Xara? something like that). It turned out that, because any graphics file produced by such an has to be updated frequently, and disabling such an integrated/complicated part of the app would not have nice results, it actually created the graphics file in their temp storage, but with an unknown file extension. Take a poke around; your work might be there (rename any "suspect" files as jpg/gif/whatever, and open them with IrfanView, which will tell you if they're graphics files with the wrong extension).

That's the guy! It was pretty damned cool, in the day. [edit] Holy cr@p! It used to be pretty damned cool and easy to use, but they've made real improvements! But they're not paying me for this, so I'll shut up.

Not quite "push of a button" but the mesh function is what you need. You can try something like this:
function meshFunction(tx, ty, Z)
ltx = length(tx);
lty = length(ty);
tz = zeros(ltx, lty);
for xx = 1:ltx
for yy = 1:lty
tz(xx,yy) = feval(Z, tx(xx), ty(yy));
endfor
endfor
mesh(tx, ty, tz);
endfunctionwith
tx = ty = linspace (-8, 8, 41)’;
and defining a function "hat":
function z=hat(x,y)
r = sqrt(x.^2 + y.^2) + eps;
z = sin(r) ./ r;
endfunctionthen
meshFunction(tx,ty,"hat");
should give you a simple 3d plot. the
txandtyare the values over the x and y ranges, respectively. The 3rd parameter is the name (as a string) of the function of x and y that returns z.A positive attitude may not solve every problem, but it will annoy enough people to be worth the effort.

Hi, I'm the author of Graphing Calculator 3D. Although exporting image to JPEG is disabled in free edition the screen capture should work (ie. using PrtScn button in keyboard). I'm not using any copy protection or cripple ware. I used screen capture myself many times without any issues. Have you tried PrtScn keyboard button in Windows? I understand that not everyone can afford the paid software so I tried to leave as much of the main features available in the free edition as possible.

You definitely should grab the professional edition ;P

I think words like 'destiny' are a way of trying to find order where none exists. - Christian Graus Entropy isn't what it used to.

Why no screen print? Try Greenshot[^] awesome, free screen grabber. If the graph can be seen on the screen I don't understand why you can't get a screen print?
New version: WinHeist Version 2.1.0 Beta Have you ever just looked at someone and knew the wheel was turning but the hamster was dead? Trying to understand the behavior of some people is like trying to smell the color 9. I'm not crazy, my reality is just different than yours!

I can't figure out what you're struggling with. Graphing Calculator looks like a pretty cool tool. I just gave it a try for the first time (used the online version) and it seems very intuitive. I only played around with it for about 10 minutes, but I made some pretty cool looking 3D graphs -- z=.5sin(y^2+6) + 2cos(x^4) -- (I call that one "The Frozen Ice Tunnel of Mordec"). My screenshot tool (Snagit) had no problem taking a pic of it. I'd say @runiter has made a pretty slick tool that I'll definitely be bookmarking. Thanks for the link!

Hey runiter, welcome to CP Lounge! I for one am quite impressed with your app. And kudos for coming online to discuss it. Hope you stick around -- this place needs more people like you.

I wholehearted support Octave, but seeing your needs I suggest the following. If you need a free option, you can screencap, but preferably say you can spare $6/month (or between $45-$65/year) for WolframAlpha. Either way, you can get WAlpha output. Here's a sample. I asked WAlpha: (x^2)+(min(x,y))-abs(y)+(xy+y^2)[^] Hope that helps.

Nor do I, but that's what happens. If you want to see an example, just waste your time like I did :-D :laugh: :(( :omg: It's some sort of anti-user thing, the freeware isn't really free, and that biz.
Have you tried window's snipping tool instead of a screen print? What's nice about that is that you don't have to use a tool like paint to cut down the amount of screen you want. Your "freeware" may not thought of that tool or may not be able to protect against it's working.

YES !!! PAY DIRT !!! You sir, are a real friend. Thank you. If you know of a similar app that will capture moving images with equal simplicity and detail, post it. This is the way it's supposed to be: click, click, drag, drag, zip, zap, I have my image Nice, I never knew this existed before your suggestion.

You do realize (yes?) that you can download a a limited freebie version for your machine.

For some reason, PrintScreen plus your package hates me, but I did find a screen shot that works. Thanks. Oh, and I fully concur with others, your stuff is absolutely fantastic.
