A method for selecting a three-dimensional object in a three-dimensional environment improves a speed and efficiency of a lassoing technique. The method reduces the number of objects that have to be rendered into images in order to determine whether the object is included within an area selected by the lasso. The method selects objects intersected by the lasso using ray picking. These selected objects are not rendered into images. The method determines those objects whose bounding boxes do not intersect a bounding box of the area selected by the lasso. These objects are also not rendered into images. The method renders the remaining objects into images to determine which are included with the area selected by the lasso.
