Abstract: A method of rendering an object is provided. The method comprises: encoding a feature vector to each point in a point cloud for an object, wherein the feature vector comprises an alpha matte; projecting each point in the point cloud and the corresponding feature vector to a target view to compute a feature map; and using a neural rendering network to decode the feature map into a RGB image and the alpha matte and to update the feature vector.
