Nowadays

mobile devices such as Pocket PC

PDA and Smartphone are used in Distributed Virtual Environment because of their portability and mobility. But mobile devices have their own limitations. For instance real-time rendering of 3D models on the mobile devices have not yet been satisfactorily resolved. In this paper

a new contour-based remote rendering algorithm for mobile device applications is proposed

which integrates the advantages of multi-resolution mesh and contour-based remote rendering

and can preserve the feature details of the models. At the preprocessing stage

the algorithm extracts the feature lines from the original mesh and then preprocess for multi-resolution mesh construction; At the real-time stage

the algorithm selects the final feature lines using a selection strategy and then constructs the appropriate multi-resolution mesh according to the interaction information

such as the viewpoint and frame rate

then extracts the contour lines from this mesh. At last

it sends the selected feature lines and the contour lines to the mobile device for rendering. Experiments show that the algorithm can preserve the details well in contour-based remote rendering

and can assure the rendering to be real-time on mobile device.
