Convert Packed Bounding Box to Polygon?

[galagast]

Hello~

Anyone knows of a quick way to convert the Bounding Box display of a Packed Primitive Geometry into Polygon?

Currently, i'm looking into just building a box based the packed intrinsics (transform and bounds) XD

You can still use the bound node on a packed primitive. That will give you six polygons and remove the packed primitive from the stream.

heya Atom!

yeah, i actually tried that.. i should have also mentioned that i wanted it to also be correctly oriented based on the packed prim orientation >__<

So far, this one worked

create_attributes (run over points)

matrix ident = ident();
addpointattrib(0, "transform", ident, "matrix");

 

get_intrinsic_attributes (run over points)

int pt = addpoint(0, {0,0,0});

// get bound size
float bounds[] = primintrinsic(0, "packedbounds", @ptnum);
float size_x = abs(bounds[0]-bounds[1]);
float size_y = abs(bounds[2]-bounds[3]);
float size_z = abs(bounds[4]-bounds[5]);
vector scale = set(size_x, size_y, size_z);

// set transform
matrix tm = primintrinsic(0, "packedfulltransform", @ptnum);
vector pos = primintrinsic(0, "pivot", @ptnum);
pretranslate(tm, pos);
prescale(tm, scale);
setpointattrib(0, "transform", pt, tm);

removeprim(0, @primnum, 1);
