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.
