art and math

strange spirals, coloured areas and esthetical solids of revolution...
I use the program “mathcad” to create pictures of such matter,

there are anybodies which do similar like it?

to show what I mean I’ll present a few pictures.

they are generated by printing a mathcad-sheet as bmp and convert than in jpg.
in original (mathcad file .mcd) one can rotate the figures, change their colors and illuminate them with diverse light…..

for a few I add the formula to show, how the analytical concept for the figures

edit: the first there is in a better version
but how I can exchange the pics ?

Nice work, Ispom. I use mathcad as well (not as much as I used to though!) but I haven't really used it for producing art.

I assisted a friend doing a math project with Kosh Snowflake Fractals..although very basic i can see that they have a certain artistic symmetry.

indeed may game program writers use this type of method for rendering of backgrounds.

This would look great in Mathcad. Not so good on my TI89.

sheeny, I'm glad because not alone with my interest,
give us a sample of your activity,

I also add a few...

That 3rd one is a savage bra!!!I like the wormhole!

Most of my mathcad stuff is for calculations. I used to use it when I was at uni and for a few years afterwards. I got a copy of mathcad a year or two ago, but really haven't used it much - just played around. These days I find I've gotten so used to working out ways of solving problems in Excel, say, that I don't have much use anymore for the heavy maths and mathcad. I used to do lots of vector, matrix and eigenvectors, calculus and differential equation type stuff in the early years of my career. I don't do that stuff any more.

Its a bit sad really because it used to seem so easy, but now I'm so out of touch with REAL mathematics...

What I really need is the time to sit down and work on project with it... I have thought about doing a plot of gravitational field strength for a 2 body orbiting system - obviously to show the Lagrangian points, but I haven't had the time to really get anywhere with it.

Do you play with the animation capability at all? I don't think Mathcad had animations back in the early days (Mathcad 1 and maybe mathcad 3 I think I used). I have Mathcad 13 now... I have no idea how much it's capable of, but I would only be capable of using a fraction of a percent of what it could do!

Al.

ha! I can do that on my TI89, rotate a function about X or y axis to create a volume of revolution.

I haven't tried 3d transformation on the TI89Titanium. Apparently it can do them although from a visualization point it wouldn't be anything like Mathcad.

Great stuff Ispom, you certainly have created some fascinating images.

Well done and very enjoyable.

me too

I use the version mathcad 8, the first which make possible so many variants for colored figures.
I have buy it 6 y ago for ca 40 USD, but the new versions are exorbitant for me

animations are possible with mcd8 for 2D figures.

well, wasy, let us participate in your TI89,
I show you a few rotation figures too

Ric, for you in downunder is now midnight already, here we have daylight still.
before I will eat my lunch, I dig up any more figures from my archive, you will enjoy them not until tomorrow, I assume


the last was especially difficult like every then, if the denominator may be zero at any places

Smile Art for Art Sake...

ispom
Doing mathematical art is quite interesting, which I have been doing on and off for ages. Using the MAC OS X, I often run POV for MAC 3.6 and a little Python program called NodeBox. Although I have experimented with POV Ray on a number of occasions, NodeBox I find the most fun. I have attached some examples of these, which can generate random patterns which can be adjusted for various effects using the fairly simple language of Python.
I have used this to do all sorts of things. Ie. generate unique business cards, which can be changed randomly for various backgrounds. A sample of two of these is below, which I rework with suitable text.
Another is the MAC program I use called Grapher 1.1, which has a simple interface and can even generate Quicktime movies. The example here is a flower-shape setting the boundary conditions and generating the various iteration variables. (See Flower image)
I have also experimented some graphic artwork by combining graphic and image editors, like example of the spiral images with the mustard yellow background. (See example.)

Be interested to see what else you are doing.

AJames
