Sample text

Mesh simplification is still an active research field in computer graphics. There is still no algorithm which is better than all others, but the following will only give a short introduction to edge collapse and its reverse operation, vertex splitting because they are popular choices and also the applications for progressivity. We use examples to illustrate the concept of simplification and the ability to progressively deliver a polygonal mesh for coarse-to-fine transmission. Interested readers can refer to [17] for more details.

Then the collapsed edge can be recovered. In other words, edge collapse is to remove the detail from a polygonal mesh, and vertex split is to recover the details and to increase the accuracy. A progressive mesh (PM) scheme [18] uses edge collapse and vertex split to achieve the delivery of details in progressive order. In the PM scheme, edge collapse is applied to a fine detailed triangular mesh for creation of a coarser mesh and the resulting coarse mesh can be reconstructed through a sequence of vertex-split refinement operations.

A detailed discussion can be found in [14]. Generally, the type of applications, the performance requirement, the size of the data and the operations to be performed affect the choice of representation. In addition, texturing techniques are important to add more lighting details to generate the realistic appearance of objects in computer graphics. 7 A cube is represented with a winged-edge mesh. 8 H10 V4 H3 H2 V2 H26 H27 H4 V5 H8 Fi V6 H25 H7 H6 H35 V1 H5 Hi H9 H24 H28 H34 H33 V0 H15 H22 H21 H23 H30 H29 H32 H13 H16 H20 Hk Vi Vj Hj Fj Hi Vi Hj Fi Hk A cube represented by half-edge meshes.
