Pemudahan permukaan telah menjadi topik kajian yang menarik dalam beberapa dekad ini. Sesetengah penyelidik memperkenalkan kaedah yang baharu manakala penyelidik lain melakukan pengubahsuaian ataupun penambahbaikan terhadap kaedah yang sedia ada. Walau bagaimanapun, model yang telah dipermudahkan mempunyai kecenderungan untuk kehilangan sebahagian daripada bentuk asalnya. Dalam pada itu, untuk mengatasi segala masalah ini, satu algoritma baru diperkenalkan, di mana formula nisbah digunakan untuk mengenal pasti calon elemen yang layak untuk dibuang. Elemen yang digunakan dalam algoritma baru ini adalah segitiga. Keputusan kajian menunjukkan bahawa algoritma yang dicadangkan dapat mengekalkan bentuk permukaan model asal. Kata kunci: Permudahan permukaan; persamaan rasional; berjenis; segitiga kontraksi; penipisan permukaan Mesh simplification has become an interesting research area over the past few decades. Some researchers have introduced various new methods while others have made some modifications or improvements to the existing method. However, the modified model tended to lose some of its original shape. Hence, to solve these arising problems, a new decimation algorithm is introduced, in which rational equation is used to select elements as candidates to be removed. The proposed algorithm also uses triangular mesh as the element. The results show that our proposed algorithm can preserve the shape of the mesh. Key words: Mesh simplification; rational equation; manifold; triangle contraction; mesh decimationDownloads
