**Question:**

Trig problems causing wildly incorrect projection of the vertices of a cube

```
function project3D(v, w, p, y) {
v=v.copy().sub(w);
let sy=Math.sin(y),cy=Math.cos(y),sp=Math.sin(p),cp=Math.cos(p);
return new Vector(
v.x*cy+v.z*sy,
v.y*cp+sp*(v.z*cy-v.x*sy),
cp*(v.z*cy-v.x*sy)-v.y*sp
);
}
```

Much more context is required here, and also much more meaningful variables names, in order for anyone to be ale to help.

WAT?Isn’t it meaningful enough?

Normally, we use whole words as variable names to make our codes easier to read. Also you cannot assume that just because no one helps no one wants to help you. I do not have the knowledge required to solve your problem, hence I do not help you. It doesn’t mean that I’m not willing to help you, but rather that any help I offer will be useless.
