A three-dimensional (3D) remeshing apparatus includes a curved surface geometry module for calculating one or more geometric elements, including a normal and a curvature, based on data of an input mesh, a vertex grouping module for grouping vertices of the mesh into a general group, an edge group, and an apex group using information of the curvature calculated by the curved surface geometry module, and a projection module for searching for one or more tangent planes corresponding to one or more of the vertices grouped by the vertex grouping module, projecting one or more corresponding vertices on each of the tangent planes, and restoring one or more edges of the input mesh.

A ripple and foam creation apparatus and method using water particle data is provided to create ripples and foam, and detect positions of the created ripples and foam for a water simulation used to create visual special effects in animations or movies. The apparatus includes a water particle grouping module checking grouping types of water particles from received water particle data to selects small water masses, a ripple creation module determining a position for ripple creation by using the checked grouping types, a foam creation module detecting flow of the water particles and calculating a position for foam creation, and a ripple-foam moving/removing module detecting changes of the created foam and ripples over time and removing the created foam and ripples.
