Friction and Electrostatics

I am as sick as a dog as I write this blog post. I woke up this morning at 5:30 with the most spectacular headache...it was like an...umm... acid trip!! I went back to sleep after taking some medication and woke up at 9, feeling a bit better, although my temperature was still high. I ate a bit and drank a lot(no pepsi this time, guys!) and settled down for a bit, while studying physics.

When I was studying physics, I ran into Coloumb's law. For the less physically enlightened among us, Coloumb's Law states that:

The force between two charges is inversely proportional to the distance between them, and directly proportional to their magnitudes.

In other words:

F = (Q1 * Q2)/ d

where F is the force produced, Q1 and Q2 are both different charges and d is the distance between those two charges.

So, you ask, how does this sloppy physics lesson concern the average retarded chump?

Well, it doesn't.

It just shows that I'm above you mortals. Just kidding. I was bored, so I went onto Wikipedia to look and see if there was a vector form. Turns out there was.

So I decided to go and create a small, utterly useless program that shows Coloumb's Law in action. It consists of a box and sphere. The box represents an electric field, and the sphere represents a charged object in the field. The box is always positively charged, while the charge of the sphere can be changed using the left mouse button. The camera can be rotated around the field so you can see it better, by using the left and right arrow keys.

Please note that I programmed this thing when my body temperature was causing forest fires in my head, so although its pretty much bug free, the source code is too messy to repost here. Instead, I'll just provide the link for the executable. It uses Irrlicht with the openGL video driver, as most of my other programs do.

The link is located under Random Programs. Grab it and go!!!

You might also have noticed that I changed the theme and layout of the blog. I figured it was about time for a change of scenery, you know? I'll probably do it about every 4 months.

That will be all, fellow human.

See ya,
Gavin

P.S. Oh, by the way, I know you guys were all shocked at the last post, and most of you couldn't believe what you saw (yeah Sparky A.K.A. Christopher Backfista, I'm talking to you). So for the pure shock value of it, here's the image again:



Congratulations, perv. Sparky, you might want to wipe that stuff off your monitor, drool or otherwise.(Ewwww....grosss.....)

Dancing in My Own Blood

No, this post has nothing to do with the title. In fact, this post is actually a programming post.

You see, yesterday, I finished LunaLib's basic math routines. Yup, you heard that right. Matrix multiplication, matrix inversion, vector cross products, basic point in polygon tests, EVERYTHING!!!

So now, I have to work on LunaScene, which I have a gut feeling I forgot to mention. LunaScene is a scenegraph with a built in physics engine, which as you all might guess, needs more work. Advanced collision detection, collision response, etc... I have my work cut out for me. But still, it's going to actually be fun.

After I finish LunaScene and have a working demo, I'll probably work on optimization of LunaLib.

I'm going to have hell learning all the physics I need. But still, no knowledge is useless. It might come in handy if I ever drop out of school and decide to make nuclear bombs for a living. lol.


Now, in a completely unrelated side note, look at this. I almost pissed myself. You will too.



See how easy it is to go to jail now, Clive?

Still...they do say, if you dress like you want it, you're gonna get it.

The studying for mock exams is coming along great though. I feel really energized as of late. I guess Pepsi really is addictive, because I've been taking it in by the gallon to stay awake. Lets hope all this pays off in the long run.

Later peeps!

Almost Done

Mock exams are on their way. All programming work has stopped. All my energy is being focused on studying and picking up girls. Need to relieve stress. Can't keep coherent thoughts....

A long time ago, I made this video. Yes, I'm KirbzXXX. Hope you like it:


I also made Boondocks and Samurai Champloo AMVs, but youtube removed them. Oh well.
