how to stuff $P into a array

[sanostol]

is there a way to get all pointpositions in a vector array?

Very likely.... but for which context?

SOP

Just thinking out loud here, but:

Feed a dummy, single-point geometry to the first input of a VopSOP, and the geometry with the points you want to put into the array into the second input, then in an inline vop (inside the VopSOP), write something like this:

vector $pts[] = array(P);
int $n = npoints(1);
resize($pts,$n);

vector $p;
int $i;
for($i=0;i<$n;i++) {
   if(!import("P",$p,1,$i)) break;
   $pts[$i] = $p;
}
float $larr[] = serialize($pts);
addattribute("points",$larr,arraylength($pts));

This would stuff the point array into a float[] attribute called "points". To recover the vectors, you'd need to unserialize() the array after importing the attribute.

Untested.

Whats with all the '$' signs?

It's meant to go inside an InlineVOP, so the '$' signs avoid symbol clashes. If this were straight VEX, then you wouldn't need them.

Ohhhh - sorry, I missed that:)
