Abstract
A method of determining a level of detail (LOD) for a texturing includes: acquiring texture coordinate data on pixels included in an upper block; determining a reference quad among quads included in the upper block; determining a similarity between the determined reference quad and the upper block using texture coordinates of the determined reference quad and the upper block; and determining LODs of remaining quads among the quads included in the upper block to be the same as an LOD of the determined reference quad in response to the determining of the similarity including determining that the determined reference quad and the upper block are similar.
