Hello Guys, is there someone who can help me? I can say i'm beginner in Houdini, but i like this powerful software.

> I'm trying to remake this nice effects.

Your text to link here... [vimeo.com]

Video is little bit faster and it's better to slowdown, because you can see what i trying to achvie.

I read one interview where Albert Omoss talking he rebuild this code from Processing to Python in Houdini, but i dont find any tips how to make it or how i can rebuilt, what nodes i can use.

Thanks.

Hey akkanein,

the video you linked contains something like a dozen of different effects. Which one do you mean?

Cheers

Hi CYTE, thanks for response, yeah in video is so much effects, my mistake that I didnt give more detailed information.

I post pictures for better understand what i mean. In my opinion it is the same setup for each other.

In last picture it's another style what i like. We can see nodes, but they are small. And i cant see what nodes he used.

Hey akkanein,

as a starting point for the first three Images you posted:
take a grid set it to points.
use an attribute noise or attribute random to assign a Cd value to the points.

There was a fun thread on twitter recently about using simple (for coders) combinations of XOR and modulo operations to make cool patterns, here's the write up:

And I've attached a version in houdini.

I'm trying to rework one video tutorial from C4D


First steps was easy to made, but next steps are more complex.

int dim = sqrt(@numelem);
vector tp = set(@elemnum % dim,@elemnum/dim,0);
float size = fit01(rand(@elemnum),0.5,1);
int prim = addprim(0,"poly",addpoint(0,tp),
           addpoint(0,tp+set(0,size,0)),
           addpoint(0,tp+set(size,size,0)),
           addpoint(0,tp+set(size,0,0)));
float area = size *size;
setprimattrib(0,"area",prim,area);

node = hou.pwd()
geo = node.geometry()
geo1=geo

# Add code to modify contents of geo.
# Use drop down menu to select examples.

attrib = geo.addAttrib(hou.attribType.Prim,"sort_i",0)
def sa_kar(prim):
    return prim.attribValue("area")

lis = list(geo.prims())
lis.sort(key=sa_kar)

for i ,prim in enumerate(lis):
    s = node.inputGeometry(0).prim(i).points()[0].position()-prim.points()[0].position()

    for point in prim.points():
        pos = point.position()+s
        point.setPosition(pos)

play with this and make some noise..Have Fun
