Abstract: Abstract: Measuring geodesicdistances on polyhedral surfaces plays an important role in many real-worldapplications. This problem was studied extensively in 80s and 90s incomputational geometry field, mainly focusing on the theoretical issues. Since2000s, computer graphics research has made significant contributions to developefficient and practical computational tools. In this talk, I will discussrecent trends on the discrete geodesic problem. In particular, I will focus on1) parallel methods for exact geodesics and 2) pre-computing methods forapproximate geodesics. I will also compare and evaluate the existing methodsfrom applications' perspective.
