3D application services are bursting on the scene constantly in various ways with the advance of 3D technology and users can easily produce 3D scenes by applying the international standard X3D, which is for giving account of 3D circumstance interacting in Internet environment, In X3D standards, 2D and 3D texture mapping has been used to enhance the quality of an image generated with a camera or to speed up the generation of an image with respect to a given scene including several geometric models. As an extension of the texture mapping, the texture image can be projected onto a 3D scene within the projection volume which is constructed from a specific projection point. A texture mapping of this type is called a projective texture mapping.
There were a few attempts to specify the projective texture mapping nodes into X3D standards. In this thesis, we have considered the projective texture mapping as the Appearance node. Users need to specify the projective texture mapping on each object in 3D scene so that a great deal of effort is required.
In this thesis, we propose an efficient method to overcome such an inconvenience. The proposed standard nodes are defined independent projector ones in order to enable X3D to provide perspective and parallel projective textures. Specially, we show the effectiveness through the implementation of the proposed projective texture nodes.
