• Kalman

  4 29 0.0 C++

  Kalman Filter (by FrancoisCarouge)

  I released a first version of a generic Kalman filter.

• SpeciaLUT

  0 27 0.0 C++

  Runtime choosing of template specializations using compile-time lookup-tables. Compile all states of a template function, but execute the optimal one at runtime.

  I made SpeciaLUT to convert bool/enum runtime tests to compile-time conditionals — by compiling all branching combinations in hot functions and saving them in a lookup-table, so the optimal one can be called at runtime. Reason: as an HPC consultant I encountered many codes that grew without good architecture, in which features would just be added and branching would propagate through all levels. This yields 10% to 50% performance increase in such codes.

  Collect and Analyze Billions of Data Points in Real Time. Manage all types of time series data in a single, purpose-built database. Run at any scale in any environment in the cloud, on-premises, or at the edge.

  

• rapidobj

  0 149 0.0 C++

  A fast, header-only, C++17 library for parsing Wavefront .obj files.

  I wrote a rapidobj library for parsing Wavefront .obj files. It's an old text format for 3D data. This library was optimised to quickly process large files (see benchmarks); it can parse millions and even tens of millions of triangles per second.

• AutoGeodesics

  1 8 10.0 C++

  Easily integrate the geodesics equation using automatic differentiation.

• LinearAlgebra

  0 4 10.0 C++

  C++20 Linear Algebra header only library, with lots of support for complex operations.

• shadow

  0 0 10.0 C++

  Simple explicit reflection library (by bergesenha)

  I wrote this reflection library several years ago to teach myself some template metaprogramming. It was originally written for C++11, but upgraded to C++14 after a while to make use of some of the improvements. It's been stale ever since, but I sometimes refer back to it when I need subsets of the functionality and need a refresher on how to write certain functionality even though I would probably have done things very different today :) https://github.com/bergesenha/shadow
