Are you slacking on your mack? If so, WHY?!?

x( tell me, please.....

1. If by "mack" you mean what I think you mean...

then it would be because I'm not even trying to go out and meet women this summer, let alone get any futher. :shrug:

[bicentennial_baby]

2. I'm simply referring to 'macking' in general...

Your mileage may vary :P

Hey you!! :bounce: How's tricks? :)

5. My values are lost in the Matrix.

And by the matrix I mean this crap:

TQ3Matrix4x4 *
E3Matrix4x4_SetRotateVectorToVector(TQ3Matrix4x4 *matrix4x4,
const TQ3Vector3D *v1, const TQ3Vector3D *v2)
{
// We accomplish the rotation by creating two orthonormal vector triads:
//
// (u, v, w) -> (u', v', w)
//
// The rotation is about the axis w. It rotates u (=v1) into u' (=v2). It
// also rotates v into v', which are vectors rotated 90 degrees in the plane
// of rotation from u and u', respectively.
//
// To construct the rotation matrix, we rotate into and out of the basis
// vectors i, j, k:
//
// (u, v, w) -> (i, j, k) -> (u', v', w)
//
// Thus the rotation matrix is the product of two rotation matrices, a and b:
//
// | ux vx wx | | ux' uy' uz' |
// | uy vy wy | . | vx' vy' vz' |
// | uz vz wz | | wx wy wz |
//
// To see this, simply multiply this composite matrix by the u, v or w row
// vector on the left and see that the result is u', v' or w, respectively.

TQ3Vector3D u, uPrime, v, vPrime, w;
TQ3Matrix3x3 a, b;

Q3Vector3D_Cross(v1, v2, &w);

// Check if vector w is roughly zero
if (e3vector3d_below_tolerance(&w, 10.0f*FLT_EPSILON))
{
// Vectors v1 and v2 are approximately parallel or approximately anti-parallel
// (within 1.192092896e-07 radians or roughly 0.000007 degrees!)

6. Are you sober this time?

I was reading about the alcoholic beverage..the 'Zombie Nixon', that is... :D

[ZombieNixon]

7. Yes.

I made more progress when I was drunk...but sadly, I finished the schnapps. I want some more; that thing was damn tasty. :9

Maybe if I was trashed I'd understand what the fuck an orthonormal vector triad is. :shrug:

[bicentennial_baby]

8. Yikes!

Would sleep help? :hug:

And, what kind of schnapps was it? :D

[ZombieNixon]

11. Something cheap with a parrot on the label.

My parents probably forgot it was there. :D

I think that you could use different fruit flavors of schnapps to make it taste more like a mixed lemonade drink...kirschwasser to make it taste of cherry and so on. These particular schnapps were tropical fruit flavored. :9

[bicentennial_baby]

12. Fascinating....

I'm on a Bloody Mary/Margarita kick with Sniffa...yum yum... :9

My favorite schnapps are Peachtree...great in the Peach Margarita too :D

[BreweryYardRat]

3. I'd have to have mack skills in the first place to slack on them.

:(

[bicentennial_baby]

4. have faith, young Padawan, and you...

will mack to the fullest in time. Trust me. :evilgrin:


:D

[Floogeldy]

9. Because I said so!

[bicentennial_baby]

10. Ah, yes...Slack away

let that mackin' wither on the vine.... :P
