For the past few weeks, I was looking for an optimized Mesh simplification algorithm.
I tried with few simplifications algorithms(QSlim, Simplified Progressive mesh etc).
Each of the algorithms have their own merits and demrits. Infact there is a tradeoff between speed and mesh quality.

In particular, I found QSlim as the best Performing simplification algorithm among them. Though the quality of simplified is not appreciable, speed of the algorithm has no match.

I did some research to understand the QSlim algorithm.But I could not figure the reason for its high speed.

Now my question is why QSlim is faster than other algorithms?

I assume that, all mesh simplification algorithms work by collapsing the edges. difference lies in the error calculation for each collaspe.
