We introduce the RGB Subdivision: an adaptive subdivision scheme for triangle meshes, which is based on the iterative application of local refinement and coarsening operators, and generates the same limit surface of the Loop subdivision, independently on the order of application of local operators. Our scheme supports dynamic selective refinement, as in Continuous Level Of Detail models, and it generates conforming meshes at all intermediate steps. The data structure used to encode RGB subdivision and to support selective refinement is very light, since it does not require to store any hierarchy. We present an interactive tool that permits to start from a base mesh and use RGB subdivision to dynamically adjust its level of detail.

Abstract
We introduce the RGB Subdivision: an adaptive subdivision scheme for triangle meshes, which is based on the iterative application of local refinement and coarsening operators, and generates the same limit surface of the Loop subdivision, independently on the order of application of local operators. Our scheme supports dynamic selective refinement, as in Continuous Level Of Detail models, and it generates conforming meshes at all intermediate steps. The data structure used to encode RGB subdivision and to support selective refinement is very light, since it does not require to store any hierarchy. We present an interactive tool that permits to start from a base mesh and use RGB subdivision to dynamically adjust its level of detail.
