Hi there,

I'm studying Houdini for some time and at this point i'm trying to create something with a little more complexity than the usual. This time, I have a pattern applied to a spherical cage and would like to add a distortion similar to the "liquify" filter from photoshop.

I've been experimenting with attribute vop but so far I couldn't get to the aesthetic that I'm looking for.

That said, is there a way or how to achieve a liquify effect on geo within Houdini? I'm attaching an image of the sphere that I created and the liquify effect that I'm looking for. Any suggestions would be appreciated.

int pts = npoints(1);
vector color = 0;

for(int i = 0; i < pts; i++){
    float age = point(1,"age",i);
    float life = point(1,"life",i);
    vector pos = point(1,"P",i);
    vector id = point(1,"id",i);
    vector ptColor =point(1,"Cd",i);
    float nage = age/life;
    
    float maxDist = chf("max_dist")*fit01(rand(id),1-chf("dist_var"),1+chf("dist_var"));
    float dist = distance(v@rest, pos);
    float width = chramp("width",nage);
    
    float sampleMaxDist = maxDist *chramp("spr_motion",nage);
    float sampleMinDist = sampleMaxDist * width;
    float intensity = chramp("intens",nage);
    vector colorTemp = ptColor*chramp("spr_ramp",fit(dist,sampleMinDist,sampleMaxDist,1,0));
    colorTemp *= intensity;
    color = max(color,colorTemp);
    }
v@Cd= color;
