Suppose you have textured a low-poly cube 1. The most major difference is produced by the vertex weighting, which, in extreme cases, does not end in peaks:

For the most part, the effect is similar but nevertheless different. Weighting affects OpenSubdiv differently in some aspects.Modeling with OpenSubdiv types is slower than with previous types.However, the GPU tessellation cannot be rendered. For example, a character animation with high subdivision can be displayed more fluidly than before. Using graphics cards-supported tessellation (breaking down of polygons into smaller triangles in the following referred to as GPU Tessellation, implemented using the Type ( OpenSubdiv Catmull Clark (Adaptive) setting), highly subdivided objects can be displayed faster than before in the Viewport. The following 3 types have been integrated into Cinema 4D. The corresponding open-source libraries are available under the name OpenSubdiv. This can, however, lead to compatibility issues between various applications, which is why Pixar made its Subdivision Surface implementation public for reasons of compatibility.

It has been implemented in various ways in different software packages over the years and has also been expanded, e.g., with the addition of vertex, edge and polygon weighting. Subdivision Surfaces is a technique that has been around since the late 70s. Several new Subdivision Surface algorithms were integrated into Cinema 4D R18.
