Hello dear Houdini artists,

I'm relatively new to Houdini and still struggling with some of the more basic concepts.

My problem is the following: I have a rectangle (created from a bound node) and I want to delete either the shorter or the longer edge of that rectangle, so that I can then create a vector that shows me the orientation of that rectangle.

How would I go about doing that? I have measured the lengths of the rectangle with a convert line node, but how can I compare the 2 lengths and remove one or the other?

Is there a better way to go about this?



I would really appreciate some help with this.

Best regards,

Julian

v@dir_short;

if(length(dir_10) > length(dir_21)){
    v@dir_short = normalize(dir_21);
}
else{
    v@dir_short = normalize(dir_10);
}
