I am looking for an algorithm that constructs Cech Complex for point clouds.
I am specifically looking for some thing in Mathematica but any resource would be very helpful.
I am looking for speeded up implementations as the traditional approach is very computationally intensive.
Regards and Thanks in advance!!!

This is an important question with many possible answers.
A good overview of computation for persistent homology is given in

An approach to constructing Cech complexes is given in Section 2.2.1, starting on page 5 in

An approach to approximating the Cech complex in Euclidean space is given in Section 4, starting on page 13, in

One of the most interesting ways to compute Cech complexes is introduced in Section 4 (especially, 4.3.1, starting on page 75) in
