A fancy visualization of planes intersecting – Part 3 (and Final)

The mystery is over! From the previous posts we have seen the way we can generate a random plane, and visualize 3 of them at the same time showing their intersecting point.

It might be enough for some simple visual purposes, but we are more ambitious than that and we want to get it fancier.planes intersecting

And that’s why I’m here! This final step would be to achieve a neat visualization of our three planes and even the equations involved. Let’s begin with what we have so far:

P = rand(3);
d = rand(3,1);
x = P\d;
hold on
drawPlane(P(1,:), d(1))
drawPlane(P(2,:), d(2))
drawPlane(P(3,:), d(3))
scatter3(x(1), x(2), x(3))

Where the function drawPlane was defined as:

function drawPlane(P, d)
[x, y] = meshgrid(-10:10);
z = -(1/P(3))*(P(1)*x + P(2)*y - d);
surf(x, y, z);

Song of the day: Rap-O Clap-O – Joe Bataan

I’ve been very funky lately. Mostly due to the stressed time in the University, I just need some happy mood to shale my head in the library of the Uni. I don’t feel that alone among the sea of geeks like me… perhaps I should not write that. Anyways.

Cheer up with Joe Bataan!

Again back to the hood!

Hey, bandita!

Well, new surprises are coming. I finally got rid of the University duties by now and have some time to invest in some new projects. Of course I will start to share all of them here. You know this creepy mind runs at different speed and in many ways.

By the moment I’m just gonna let you know that video is highly involved in these new activities. Finally I can give some more visual material as I was planning from the beginning. I hope you all like it and please give some feedback. In the beginning will be slow as I gain some experience but please don’t be desperate. I’ll be updating constantly and giving again some tips and other sections will be back. Oh yeah, baby, the old school is back!

Now I have the support of many persons and I’m getting some cool ideas to apply. The visual material will be mainly in youtube and vimeo, but I’ll tell you the details later when the stuff is done. Well, wait and see, banda.

When I became an asshole.

I don’t really remember, I don’t even know how it happened, but I’ve realized that I became an asshole. Maybe it was the change of the country, or maybe I was already like this when I came, I still don’t know and I can’t explain it.

Sometimes we can not say who we are, until others say it. Now I know, well… I have a better idea, and the most accurate is that, because it was told to me. I can’t find any explanation, but it is the only feedback I have: I’m an asshole.

When did it happen?
Well, I don’t know.
Am I?
I don’t know.
Will I be?
Fuck! I don’t even know now what an asshole is.


El mileurismo es un concepto muy poco conocido en el ambiente occidental, ya que se aplica de forma válida sólo a la región europea, pero ¿qué es mileurismo?.

El mileurista, propiamente dicho, es aquel personaje que no gana más de mil euros al mes; así se puede definir. En forma más profunda, un mileurista no contempla una vida llena de lujos, ni tampoco se preocupa por mayores necesidades, simplemente trabaja, se mantiene y sigue con su vida.

Para ser mileurista se necesita haber estudiado mínimo una licenciatura, por ello también aplican todos aquellos con maestrías, especialidades, doctorados, dominio de idiomas, etc. Es decir, son personas muy bien preparadas que dentro de su entorno no tienen ingresos adecuados a su preparación.
