Websimplify_decoder. Reduces the number of triangles in the mesh, attempting to preserve mesh appearance as much as possible. simplify_sloppy. Reduces the number of triangles in the mesh, sacrificing mesh appearance for simplification performance. The algorithm doesn't preserve mesh topology but is always able to reach target triangle count. WebThe second simplification algorithm, meshopt_simplifySloppy, doesn't follow the topology of the original mesh. This means that it doesn't preserve attribute seams or borders, but it can collapse internal details that are too small to matter better because it can merge mesh features that are topologically disjoint but spatially close.
