We introduce a compressible representation of 3D geometry (including its attributes, such as color texture) intermediate between polygonal meshes and point clouds called a polygon cloud.\u00a0 Polygon clouds, compared to polygonal meshes, are more robust to live capture noise and artifacts.\u00a0 Furthermore, dynamic polygon clouds, compared to dynamic point clouds, are easier to compress, if certain challenges are addressed.\u00a0 In this paper, we propose methods for compressing dynamic polygon clouds using transform coding of color and motion residuals.\u00a0 We find that dynamic polygon clouds can improve color compression by up to 2-3 dB, and can improve geometry compression up to a factor of 2-5 in bit rate, compared to static polygon clouds and a fortiori static point clouds.<\/p>\n","protected":false},"excerpt":{"rendered":"
