[idea] ofNodeMesh

I'm working on an idea to mix an ofMesh with ofNode, so we can have a matrix transformation to draw a mesh, or a way of getting transformed (like baked transformations).

I think it has great potential, works like a 3dPrimitives but only extending two already existing objects, useful for working with meshes intersections.

EDIT: updated code, working great.

class ofNodeMesh : public ofNode, ofMesh {
public:
	
	void setMesh(const ofMesh & m) {
		(*(ofMesh*)this) = m;
	}
	void setNode(const ofNode & n) {
		(*(ofNode*)this) = n;
	}
	
	void operator=(const ofNode & n) {
		(*(ofNode*)this) = n;
	}
	void operator=(const ofMesh & m) {
		(*(ofMesh*)this) = m;
	}

	void draw() {
		ofPushMatrix();
		ofMultMatrix((*(ofNode*)this).getLocalTransformMatrix());
		(*(ofMesh*)this).draw();
		ofPopMatrix();
	}
	
	ofMesh getTransformedMesh() {
		ofMesh transform = (*(ofMesh*)this);
		for (auto & v : transform.getVertices()) {
			v = (*(ofNode*)this).getLocalTransformMatrix() * glm::vec4{ v, 1.0f };
		}
		return transform;
	}
};

Start by reviewing the existing ofNode and ofMesh APIs and the proposed ofNodeMesh code in the issue. No repository files, tests, or acceptance criteria are named; progress would require agreeing on the API, transformation behavior, and a concrete definition of done before implementation and tests can be scoped.
