VectorD Library
Jun 10^th, 2005, 10:51am

Hi,

just coded a 2D and 3D Vector library.

http://wilma.vub.ac.be/~aarrassi

Don't forget it's an super-alpha-version-coded-between-two-exams-library. So don't forget this when you'll used it for your-high-tech-research-program-on-planetary-motion.

Examples are also available.

My inspiration was the Robert Penner Flash MX vector library to describe motions. But a merged it with some function found in the book "Beginning Math and Physics for Game Programmers" from Wendy Stahler.

That's it have fun.

Very nice and clean. This is interesting.

Have a look at my own implementation for comparison. I focused a lot of mine around being able to transport vector data into angular and distance data, as well as being able to create new vectors from another vector's angular and distance displacement.

I also wrote a physics library on top of that:

btw you should export your applets with P3D, as the processing renderer right now is extremely slow...

keep it up! XD

I'm right in the middles of my exams, so I have to focus on something else. But if you agree next month i'll be free like a bird and perhaps we could merge your library with mine and take the best of both. Tell me what you think of this.

I've been using David Heubners (myT's) FVector class widely in a new 3D camera interface - I think its very good, certainly has all the features I need:

Coincidently he released it like yesterday (not to beat you to the bullet or anything

)

Indeed,

but his library is focused on vector with N dimension.
Altought I don't think going to more than 3 dimension is interestring for computer graphics.

I don't think his library and my are concurrent but either complementary.
For example he does'nt has some simple function that are useful when
drawing in processing; normalize, negate , reset.

The fact that he is concentrating on vector with N dimension make it
in theory a little bit slower cause he has to use 'for-iteration' to acces
first,the second and the third element.

In conclusion the library differ in many point.
But hey, aren't we all here for one thing.

Making processing better.

What I target with my library in the futur is to extend it
to a physics library and to add motion equation to the vectors and perhaps
to have one game engine class with all the stuff necessary for games.

That's it. Thanks to indicate me that some people already made some stuff.
It can only make processing better.

Hi Zakaria here's my response to your email:

In response to your rotations, I think you want this snippet of code:

Code:


    ang=radians(ang);
    x+=cos(ang)*magnitude;
    y-=sin(ang)*magnitude;

That will give you a new X,Y pair based on a previous X,Y, plus a rotation (ang), and distance (magnitude).

Enjoy!
