method in Houdini 19 that we gonna use for driving points(in Chops) and volumes, Uv's and other stuff soon.

4@m = ident(); 
f@d = distance(@P,(0,0,0));
f@s = chramp('speed',@d/2.4);
rotate(@m,@s*@Time,2);
@P*=@m;

 

vector x, y;
makebasis(x, y, v@N, {0,1,0});
p@orient = quaternion(set(x, y, v@N));

vector pos(float u,t){
        vector p = set(0,0,u);
        p+= u *0.2*curlnoise(p+0.1*t);
        return p;

for Particles and Chops

float pscale = chramp("pscale_ramp", float(@ptnum) / (float(@numpt)-1.0));

f@pscale = pscale;

f@locate = float(@ptnum) / float(@numpt);

float up_gap = radians(360.0 / float(chi("divisions_max")) * float(@ptnum)) * 0.5;
vector4 quat = quaternion(up_gap, v@N);
v@up = qrotate(quat, v@tangentv);

Have FUn .."Help with some model"------- jump in

[rickvdvulkaan]

this is so weird and at the same time incredible

[Librarian]

have Fun @rickvdvulkaan..
This we gonna use for colors and driving everything to make models on the Fly with Freq noise or other SCHUM..please have qLib installed.
Experiments to play and Participate if you Want

this we gonna use soon in Chops for Patterns on Skin (by for-each in Chops).

Usage for mirroring Audio and midi files(on points and with tuning(use Attrbuilder from Qlib)  on Colors) that we gonna use to make patterns on Platonic shapes. Have Fun.

for later Control with "DisneyHair" and some other shading method 2d 3d .have FUn

Ah well, you are getting closer.

We were starting to get impatient
