worldToScreen问题

/**

* @param worldPos the world position to be transformed
* @returns the resulting vector
*/
public worldToScreen(out: Vec3, worldPos: Vec3 | Readonly): Vec3 {
const ySign = this._device.capabilities.clipSpaceSignY;
const preTransform = preTransforms[this._curTransform];

    Vec3.transformMat4(out, worldPos, this._matViewProj);

    const { x, y } = out;
    out.x = x * preTransform[0] + y * preTransform[2] * ySign;
    out.y = x * preTransform[1] + y * preTransform[3] * ySign;

    const width = this.width;
    const height = this.height;
    const cx = this._orientedViewport.x * width;
    const cy = this._orientedViewport.y * height;
    const cw = this._orientedViewport.width * width;
    const ch = this._orientedViewport.height * height;

    out.x = cx + (out.x + 1) * 0.5 * cw;
    out.y = cy + (out.y + 1) * 0.5 * ch;
    out.z = out.z * 0.5 + 0.5;

    return out;
}

这个方法对于3d场景的正交相机获得结果不对呢
