FS calculating plane normal

graham_lock

Hi,

I'm creating a plane at an offset from a reference plane which I also want to angle at a given number of degrees.

My test code looks like this:

const p is Plane = plane(

                offsetDirection ? (refPlane.origin - (offset * refPlane.normal)) : (refPlane.origin + (offset * refPlane.normal)),

                vector(0, 0.1, 0.3)

                );

            opPlane(context, id + "plane1", {

                        "plane" : p

                    });

How should I go about generating the normal vector to achieve the desired angle?

Thank you.

FeatureScript transforms are great, they do a lot of heavy lifting for you.

If you create a rotation transform:

var rotationangle = rotationAround(X_AXIS, 30*degree);
var newVector = rotationangle*oldvector;

The one thing is that it only works with vectors that have a length.
So you'll need to take  your normal, give it units (ie oldvector*meter), rotate it, and then remove units (newVector/meter)
