The use of 3D models, represented as a mesh, is growing in many applications. For efficient transmission and adaptation of these models to the heterogeneity of client devices, progressive compression techniques are generally used. To protect the copyright during the transmission, watermarking techniques are also used. In this thesis, we first propose two progressive compression methods for meshes with or without color information, and we present a joint system of compression and watermarking. In the first part, we propose a method for optimizing the rate-distortion trade-off for meshes without color attribute. During the encoding process, we adopt the quantization precision to the number of elements and geometric complexity. This adaptation...
