PVector 4th element

Dawars

Hi!

I am developing a library for Processing and I need to do some 3D matrix-vector multiplication. I don't seem to be able to multiply a PMatrix3D with a vector

I see in the source that the w coordinate is commented out so it may have worked in the past.

Why is it commented out? Is there any other way to multiply a 4x4 matrix with a 1x4 vector?

Can I check and possibly readd this functionality?

First I would read this (skip the opening post).

I would just make your own vector.

What you also could do is something like:

public class PVector4 extends PVector {
    public float w;

    // now add all required constructors and procedures
}
