nodes in vex

[Follyx]

dies this exist anywhere? A sheet with vexcode for nodes wich arent written in vex.

i.e. Attrib transfer:

-assigning the value to existent variables.

-an if then for non existent variables etc.

-creating non existent variables

blahblah....

that would be good.

attrib transfer in vex is pretty easy actually.

You just need an attribwrangle and type @P = v@opinput1_P; (if you want to transfer P for example)

this transfers the P of input1 to the P of input0

This is because by default attribwrangle matches attributes by id (you can see/change that in bindings tab)

Great ! I didn't know that you can transfert by id.

But is there a way to do it like attrib transfert by distance without the cost of using a point cloud ?

If you compare the cost of attrib transfert versus a pcopen in wrangle, there is a huge performance difference.

another way to copy attributes from another input is to use the "findattribval" function

it returns the point number of the given input if it founds it or -1 if it doesn't find.

int match = findattribval(1, "point", "name", s@name);

if(match!=-1) @P = point(1, "P", match);

You could use xyzdist and primuv, but I think that may be slower than pcopen and attrib transfer!

 

int prim = @primnum;
vector uv = @uv;
float maxdist = ch("maxdist");
xyzdist(1, @P, prim, uv, maxdist);

@Cd = primuv(1, "Cd", prim, uv);
