A three-dimensional (3D) graphic rendering apparatus is provided. The 3D graphic rendering apparatus includes an object-information extraction module which extracts a bound box of each of a plurality of objects, including an i-th object and a j-th object, wherein i and j are natural numbers; an object alignment module which aligns the i-th object and the j-th object according to distances of the i-th and j-th objects, based on the extracted bound boxes of the i-th and j-th objects, from a visual point; and a rendering module which sequentially renders the aligned i-th and j-th objects such that an object among the i-th and j-th objects distant from the visual point can be rendered earlier than an object among the i-th and j-th objects less distant from the visual point.
