Abstract : Realistic visualization of crops, forest, peri/urban, natural scenes raises high interest under the environmental pressure and social demand. Unfortunately, despite the capabilities of the Internet and graphic boards, virtual landscapes and scenes are still restricted to small-scale user communities, with low dynamics, low aestheticism, low respect for biophysical laws. Web large-scale VR vegetation scenes are a challenging topic, due to the complex geometry and its rendering; and due to the lack of efficient modeling method and dynamics understanding. Moreover, VR must involve close objects that can interact easily with contextual background objects as to settle applications. However, specific solutions exist, and some of them can be used for WebVR display: light weighted static plant models, paged land scape map geometry, procedural vegetation generation on the fly. Reconstructions from photos, mixture of real and synthetic images in augmented reality are also of interest for this topic. On the study case "the Ecological project of Chinese ChongMing Island", new techniques are shown: Plant billboards and hybrid models, VRML classical scenes of historical farms, and guided maps with 3D web flash panoramic spot views. Perspectives are finally exposed from new developments: rule based geometry generation Web browsing, fast reconstruction from image models, high-level simulator output, with a background of new Web and graphical hardware approaches.
