Couldn't stop tinkering

I couldn't stop tinkering with the root basin program.

New features:
All mouse control: no keyboard means no illegal input to crash program.
Reset coordinates button: returns bounds of image to initial values
Save image: save the basin image as a JPEG.

I may do the same for the Mandelbrot program sometime. I've been in hardcore geek mode the past few days. I even started to re-read "The Fractal Geometry of Nature" by Benoit Mandelbrot. Yes, I own a copy. I've had it since high school.

I told you, I'm a geek.

Perfected

I've perfected both the Root Basin and Mandelbrot programs to my satisfaction.

I got rid of the black specks completely in the Root Basin Program.

I added a feature to both that lets you select the zoom area with the mouse.

They're pretty cool now.

I found the problem

The black specks showed up because I was too precise in my routine to determine which color the pixel should be.

I am not sure what caused the overflow error, but I can avoid it by offsetting 0+j0 from the exact center of the image.

Check these out:




















Oh yeah, I solved the slowness problem, too.

Those black specks are actually kind of cool. I may put them back in.

Ooh, pretty...

Here's an enlargement ot the corner I posted yesterday.

You can really see the fractal nature of the bounadry between basins.


















I still don't know why I'm getting those black specks.

Programming

I've been trying to rewrite my old root basin program in Borland C++ Builder 6.

Right now it sort-of works. It's slow as hell, I get floating point overflow errors, and for some reason some points don't compute right (the black specks in the image). I'll keep working on it off and on.
Here's what I managed to get so far: (it would take days for the entire image to draw, so this is just one corner)

















Here's a sort of extrapolated image:

















I got frustrated and wrote a Mandelbrot program instead. It was easy. Here's the result:












I once wrote a Mandelbrot program for my HP-20S graphing calculator, because I was bored in class. It isn't that I'm all that good, it's just that a Mandelbrot program is that easy.

Atheist video

I came across a link to this video while reading the commentaries on the JREF site. (see sidebar)

There are also two responses.
I didn't see much sense in them. The bad grammar is entirely within expectations.

For example there was that old chestnut, "Well, those people aren't real Christians ^TM."
From an atheist viewpoint, there is no substantial difference between a nut who actually believes, and a nut who only claims to believe. We aren't psychic, we can only go by the stated motives.

Am I the only one who finds the accusations of quote mining to be highly ironic?


However, neither "Atheist" or "Re: Atheist" (either of them) are going to have an effect on anyone not already in agreement. There is no common ground to bridge the gap. Theists will say, "So what." to the information presented in "Atheist." Atheists will say the same to the response videos.

Still, it was pretty cool to learn about famous atheists.
Not that a "Who's Who" list of atheists really matters.
It isn't what you believe that counts; it's what you do.

And, as "Re: Atheist (2)" ends: "For more information on Christians, see the Bible in its entirety." Yes, please do, just don't forget the "in its entirety" part.

This is hilarious!
