DEVELOPMENT OF AN EFFICIENT SIMPLIFICATION METHOD FOR 2D AND 3D HYBRID MESHES IN COMPUTER GRAPHICS APPLICATIONS

In the preprocessing stages of the computer graphical software. The Meshes are used to approximate and describe the models. These Meshes follow specific structures and they are made up of various elements. In many applications, there is no need to use massive and very detailed meshes. To simplify meshes, some methods are used which are known as coarsening methods. These methods simplify a mesh in such a way as to has the most similarity to the original shape. However, degradation of the mesh must be kept to a minimum and the structure should be maintained as much as possible. The objective includes creating a method for coarsening 2- and 3-dimensional hybrid meshes with acceptable accuracy; providing an appropriate platform for conducting research on hybrid meshes; reducing the final size of the designed meshes for rendering operations; accelerate the transfer of meshes on the network platform; increasing network data transfer speeds because of the mesh size reduction; facilitation and acceleration of convergence in solving equations of calculating external flows by simplifying the computational meshes.
