Abstract: Provided is a method for generating high-quality isosurface mesh in real time, which takes the Marching Cubes algorithm as a baseline to efficiently generate a high-quality mesh of a 3D model, re-examines the case table in the MC algorithm, and puts forward the concept of equivalent edges. By combining with the remeshing technology, the MC algorithm is optimized from three aspects: deleting equivalent edges with the worst performance from the case table by using connectivity modification and vertex insertion technology; changing the geometric shape of the active edge to make it more perpendicular to the isosurface; and moving the shared cut points of cube cells. According to the present application, the mesh with a higher quality is generated at the running speed close to the standard MC algorithm, and the mesh quality is close to the post-processing remeshing algorithm with extremely high time consumption.
