This paper presents algorithms of complex web\|based 3D scenes texture transmission rendering. Current display methods transmit an entire texture to the client before it can be used for rendering. We present an alternative method which subdivides each texture into tiles, and dynamically determines on the client those tiles that are visible to the user. Texture tiles are requested by the client in an order determined by the number of screen pixels affected by texture tiles, so that texture tiles which affect the greatest number of screen pixels are transmitted first. The tile visibility calculations take full account of occlusion and multiple texture image resolution level with each new frame dynamically recalculated each time it is rendered. We show how to improve the rendering capability without architecture changes.
