This paper brings to iterative selection criteria to improve simple adaptive subdivision surfaces method in handling cracks for triangular meshes. Adaptive subdivision is a method that subdivides only at certain areas of the control mesh. Although subdivision occurs in the selected areas, the quality of produced surfaces can be preserved similar to the regular subdivision surfaces. Traditionally, subdivision surfaces were applied to the entire model in order to produce smooth surfaces refinement from coarse meshes. Several schemes had been proposed in this area to provide a set of rules to converge smooth surfaces. However, to compute and render all the vertices are inconvenient in terms of memory consumption and run time while the subdivision process converges to a limit shape. It will lead to heavy computational loads especially at a higher level of subdivision. The result brings to an outcome that subdivisions of entire meshes are unnecessary. Nevertheless, adaptive subdivision suffers with two weaknesses; difficult to select necessary areas needed to be subdivided, and to remove cracks created from the subdivision depth difference between the selected and unselected areas. Cracks must be removed because it creates artifacts in editing, rendering, and processing of the mesh. The result of comparison for simple adaptive subdivision surfaces method has been presented.
