Current Progress: Poster done and a few flaws remain

So in the past week, we made several models with our plugin successfully, including the China Pavilion on World Expo Shanghai 2010, a gun and also some random shapes. These examples showed the eligibility of our work to model 3D objects from 2D silhouettes, as well as the ability of real time user interaction. We will show the screen shots by the end of the report.

However, we have also found some new bugs, which are generally related to the combination with Maya operations. We voided the uniqueness of each vertex, but append each vertex to the PointArray even it has existed, i.e. it has the same position with one of the appended vertices in the PointArray. In doing so Maya cannot merge the meshes correctly. It is so implicit that we can not identify the problem merely from unsmoothed polygons. However, if we try to smooth the mesh using Maya MEL, we will get wired output. Normals are also not always right in real time user interaction. Although we can modify the normal using MEL, we think it is best for us to adjust the order of vertices to get it correct.

That is our goal in the following week.
