Abstract: We present a method for compact encoding of attributes such as normal vectors defined on a triangle mesh of arbitrary topology suitable in the context of view­dependent simpli­fication. It is based on the recently introduced CAME data structure (Compressed Adaptive Multiresolution Encoding). In accordance with the vertex hierarchy defined by mesh simplification, we define an attribute hierarchy to track attribute values within the multiresolution representation. It is shown that the corner subgraph describing the relations between attributes in a mesh simplification step can be efficiently en­ coded if attributes are properly ordered.
