  1. Destruction

    Hey, This is a personnal project I did this year with Axel Blin. I did all the Fx, rendering and compositing. Axel made the Animation.
  2. Learning challenge Vex

    I'm not very good on matrix but you can use matrix with so many way. using quaterion matrix3 ect.. there is an ther way to achieve this exercice without matrix. replace the second wrangle by that: float pt01, twistx, twisty; vector x, y, z; x = v@tangentv; y = v@up; z = v@tangentu; pt01 = float(i@ptnum)/float(i@numpt); twistx = sin(pt01 * ch("amount")) * ch("strength"); twisty = cos(pt01 * ch("amount")) * ch("strength"); x *= twistx; y *= twisty; v@at = x + y; v@N = v@tangentu; v@up = v@at;
  3. Learning challenge Vex

    If you remember the last picture I posted after the poly frame create a wrangle : v@up = cross(v@tangentv, v@tangentu); v@at = v@tangentv; after that a new wrangle: float pt01 = float(i@ptnum)/float(i@numpt); pt01 = chramp("shape", pt01); matrix m = ident(); float angle = radians(ch("angle")*pt01*100); vector axis = v@tangentu; vector Newm; rotate(m, angle, axis); v@at *= m; and your @at is twist

    cool ! tomorrow I will post the normal rotation with matrix and the version with sin
  5. Learning challenge Vex

    thank you Kiryha, today I finish the exercice with the normal I will send tomorrow what I wrote on the wrangle. I do the vop challenge too, for that , after I will try to convert vop node into vex and vex into vop, if you have some exercice in vop to give me, you can the principe of this topic is to practice and practice a lot
  6. Learning challenge Vex

    I just finish it, it was very complicate to understand everything with array ect.. So for today if someone have an exercise to propose
  7. Learning challenge Vex

    yep, I’m trying to do a rope only in vex, by this I mean the rope, I’m a little bit lost about how twist the vector to creat the rope
  8. Learning challenge Vex

    Thanks for these informations, tomorrow I will try without @age, I have a question, I,m trying to do a rope. So I did a line, resample, polyframe with tangentu and tangentv my question is what is the best way to achieve this ?
  9. Learning challenge Vex

    I did the rotation in an other wangle with that : @age = @ptnum; @P.y = fit01(@age, 0.1, 1)+@age/ch("heigth");
  10. Learning challenge Vex

    Hey kiryha thx for your participation and for my first exercise of the week !
  11. Learning challenge Vex

    Thank Atom I will study the ramp
  12. Learning challenge Vex

    I finish it ! If you have a new one ?
  13. Learning challenge Vex

    Thanks Jon3de for the first exercise !
  14. Learning challenge Vex

    Hi all, I started to learn Vex, But I think it's better for me if I have some exercises. I mean like on this topic : It can be very cool to do this method for vex too, like this everybody can participate and learn. Of course each day the exercise need to be a little more complex. Thanks and I hope you will like the idea.
  15. Rocket Launch

    Hi All ! This is my last project of my short movie a rocket launch ! I made for my last year at school ! I done modelisation, texturing, rig, and animation of the rocket and all Fx. I used maya and renderman for the rocket and Houdini and mantra for FX Amine Amahadar done the matte painting and Anthony Carlone the compositing. https://vimeo.com/213220367
