I'm currently looking into Mesh Simplification to batch-simplify a large amount of .obj files. It is necessary for these algorithms to preserve the visual representation of a mesh as well as possible.
During research I've stumbled over Garland & Heckberts Surface Simplification Using Quadric Error Metrics. Most of the frameworks I've inspected are making use of this algorithm for Mesh Simplification.
My question is, why are most frameworks not making use of seemingly more advanced algorithms e.g. Simplifying Surfaces with Color and Texture using Quadric Error Metrics or comparable? Is the Quadric Error Metric currently state of the art concerning simplification algorithms?
