3d meshes are one of the most common representations of 3dobjects that have been used in graphics applications. They often require a huge amount of data for storage and/or transmission. In this paper, we present a new compression algorithm based on stripification of the geometric models that enables us to progressively visualize the 3d models during their transmission. The proposed algorithm encodes the geometry and the connectivity of the input model in an interwoven fashion. The main idea is to store 3dobjects as strips files. The algorithm achieves compression ratios above 61 : 1 over ASCII encoded formats resulting in faster transmission and rendering of complex graphical objects.

In our present society, 3dobjects play an increasingly important role in many different domains, especially with the development of meta environments. Many applications demand large 3dobjects, which makes their compression a requirement. Meanwhile, 3dobjects are also exposed to various security problems during online storage and transmission. Consequently, security aspects such as copyright and authentication are essential for 3dobjects. In this paper, we propose a simultaneous 3dobject watermarking andcompression method based on draco. A watermarking step is integrated within draco, Google's 3dcompression method, which is rapidly being universally adopted as standard. The proposed method enables a large bit embedding rate, which can be used for copyright information. The proposed method is also, to the best of our knowledge, the first watermarking method for 3dobjects compressed with draco.
