Hscript, Vops, Vex (and python), which to use? Point Sop with if statement Point Vop with if statement Point Wrangle with if statement Point rays, promote parameters Using point to move edges Point and attribute transfer together Point and attribute transfer with lag via solver sop No really...
Its this sort of stuff that makes me wish blueprint had the equivalent of a vex wrangle. Still, works.This is a little example of printing stuff to the screen, and constructing strings. Again, the lack of a text field to just construct strings is irritating, but this works well enough....
VEX代码如下: vectormobiusInverse(vector o,m;float r){float a=r*r/(pow((m.x-o.x),2)+pow((m.y-o.y),2));returnset(a*(m.x-o.x)+o.x,a*(m.y-o.y)+o.y,0);}voidgetCircle(vector p1,p2,p3;exportvector center;exportfloat radius){float x1=2*(p2.x-p1.x);float y1=2...
Creating magical effects in Houdini is fast, easy, and looks great. With the simplicity of USD, and the rendering capabilities of Karma, the Magic Cauldron tutorial showcases how an FX artist can improve their workflow and create production ready magical elements. Simple VEX, sparse pyro, and ...
int soho_multiframe If this parameter returns non-zero, thesoho_programwill only be invoked one time, regardless of the frame range of the ROP. int soho_initsim If this parameter exists and evaluates to a non-zero value, the output driver will initialize all simulation OPs before invoking ...
// VEX uses C-like syntax for for-loops int valA = 2; for (int i=0; i<11; i++) { valA *= 2; } i@valA = valA; // for convenient iterating over elements of an array we // can use foreach loop int nbs[] = nearpoints(0, v@P, .5); vector P_avg = {0}; foreach...

vex string tops = "`pdgattribvals('image_path')`"; string paths[] = split(tops,' '); foreach (string p; paths) { int pt = addpoint(0,0); setpointattrib(0,'image',pt,p); } Sweet: Now we can use a sops for loop in points mode to do work, here I use this to make a...
Now to push that to a font sop. I use a wrangle in detail mode so I can extract an element from that array per frame, and store it as another string attribute: vex string fonts[]=detail(0,'fonts');s@font=fonts[int(@Frame)]; ...
If you know enough vex to write a wrangle or two, JavaScript is fine. My particular focus with it is on React Three Fiber, a React wrapper around Threejs. Seemed scary at first, but hasn't taken long to get mildly productive with it. React introduces a bunch of unfamiliar terms like ...
