Problem with particle coordinates

I am trying to use a particle to draw a beam from the player to the target. Instead the particle a good distance from both the player and the target:

The code:

	@Override
	public void renderParticle(BufferBuilder buffer, Entity entityIn, float partialTicks, float rotationX,
			float rotationZ, float rotationYZ, float rotationXY, float rotationXZ) {
		Vec3d lookVec = Helpers.getEntityLook(Minecraft.getMinecraft().player, 1).eyePosition;
		drawBeam(buffer, origin, target, lookVec, 2);

	}
	public static void drawBeam(BufferBuilder buffer, Vec3d S, Vec3d E, Vec3d P, float width) {
		Vec3d PS = S.subtract(P);
		Vec3d SE = E.subtract(S);

		Vec3d normal = PS.crossProduct(SE).normalize();

		Vec3d half = normal.scale(width);
		Vec3d p1 = S.add(half);
		Vec3d p2 = S.subtract(half);
		Vec3d p3 = E.add(half);
		Vec3d p4 = E.subtract(half);
		int brightness = 240;
		int b1 = brightness >> 16 & 65535;
		int b2 = brightness & 65535;
		buffer.pos(p1.x, p1.y, p1.z).tex(0.0D, 0.0D).lightmap(b1, b2).color(255, 255, 255, 128).endVertex();
		buffer.pos(p2.x, p2.y, p2.z).tex(1.0D, 0.0D).lightmap(b1, b2).color(255, 255, 255, 128).endVertex();
		buffer.pos(p3.x, p3.y, p3.z).tex(1.0D, 1.0D).lightmap(b1, b2).color(255, 255, 255, 128).endVertex();
		buffer.pos(p4.x, p4.y, p4.z).tex(0.0D, 1.0D).lightmap(b1, b2).color(255, 255, 255, 128).endVertex();

	}
