3D Mesh Model and Its Cylindrical Image

In order to render three-dimensional virtual scenes more realistically, One often needs to draw images of objects which are reflected by the cylindrical surface mirror. Doing so, we first define the cylindrical image model as the set of image points, in which each element is the image of vertex in original model, reflected by the cylindrical surface mirror, also with the same connectivity as the original model. We determine the reflective point for corresponding vertex by the ray tracing method, which is the key step for generating the image model. In order to accelerate the generation and rendering processes, we conduct visibility test, computing only the part of image model visible for current viewpoint. We also provide the experimental results that validate the algorithm and show timing statistics of the algorthm.
