Handmade Math
A simple math library for games and computer graphics
A single-file, cross-platform, public domain game math library for C/C++. Fully inlined HandmadeMath.h. No need for HANDMADE_MATH_IMPLEMENTATION anymore. Added extra parentheses around some macros. Renamed the 'Rows' member of hmm_mat4 to 'Columns'. Since our matrices are column-major, this should have been named 'Columns' from the start. 'Rows' is still present, but has been deprecated. Added array subscript operators for vector and matrix types in C++. This is provided as a convenience... -

OpenGL Mathematics
Highly Optimized Graphics Math (glm) for C
Highly optimized 2D|3D math library, also known as OpenGL Mathematics (glm) for `C`. cglm provides lot of utils to help math operations to be fast and quick to write. It is community-friendly, feel free to bring any issues, bugs you faced. Almost all functions (inline versions) and parameters are documented inside the corresponding headers. OpenGL-related functions are dropped to make this lib platform/third-party independent. Make sure you have the latest version and feel free to report bugs... -

OpenTK
The Open Toolkit library is a fast, low-level C# wrapper for OpenGL
The Open Toolkit is set of fast, portable, low-level C# bindings for OpenGL, OpenGL ES, OpenAL, and OpenCL. It runs on all major platforms and powers hundreds of apps, games, and scientific research programs. OpenTK provides several utility libraries, including a math/linear algebra package, a windowing system, and input handling. OpenTK is not a game engine, nor does it try to be one: It offers a useful set of tools and lets you decide how to use them. It is the ideal starting point if you... -

Ray Tracing in One Weekend Book Series
The Ray Tracing in One Weekend series of books
The Ray Tracing in One Weekend series of books are now available to the public for free online. They are now released under the CC0 license. This means that they are as close to public domain as we can get. (While that also frees you from the requirement of providing attribution, it would help the overall project if you could point back to this web site as a service to other users.) These books are formatted for printing directly from your browser, where you can also (on most browsers) save... -

fast_float
Implementation of the C++ from_chars functions for number types
The fast_float library provides fast header-only implementations for the C++ from_chars functions for float and double types as well as integer types. These functions convert ASCII strings representing decimal values (e.g., 1.3e10) into binary types. We provide exact rounding (including round to even). In our experience, these fast_float functions many times faster than comparable number-parsing functions from existing C++ standard libraries. It parses the character sequence [first,last... -

pFq
Generalized Hypergeometric Functions
pFq is a math library that computes generalized hypergeometric functions by series approximation as well as derived functions. The current version pushes direct series evaluation about as far as it can go without resorting to arbitrary precision floating point. Nonetheless, for many applications, the current precision may be adequate. Often, the precision exceeds the available test functions. An approach that is intended to be a significant improvement is being actively researched. -

The Edge Machine Learning library
Machine learning algorithms for edge devices
... of magnitude lower than other modern ML algorithms. The trained models can be loaded onto edge devices such as IoT devices/sensors, and used to make fast and accurate predictions completely offline. A tool that adapts models trained by above algorithms to be inferred by fixed point arithmetic. -

FFT for ARMv6
Fixed point 16/32 integer FFT library for the Raspberry Pi and Android
This library is being created as I have a need to do very fast FFTs on low end devices not supporting the NEON instruction set. The Raspberry Pi is an ideal candidate for developing in gcc before porting to JNI for low spec Android devices, hence it's inclusion. Fixed point 16/32 integer FFT library suitable for the Raspberry Pi and Android devices. Includes test stubs for gcc on the Raspberry Pi and a Basic4Android wrapper from JNI. It includes hand optimised ARMv6 assembler... -

Algeo#
A class library to use conformal geometric algebra in C#
The project is in a very early state and the working parts aren't well tested! Currently it's possible to do basic calculations with multivectors. A lot of operators are overloaded so that you can write your calculations in C# source code almost like you would do in a math software. There is also an extension library providing a control which can visualize multivectors. Visualization is based on OpenGL through the OpenTK library. At the moment I'm working on improvements... -

MathX
Fixed-length Arithmetic-types library
MathX is a fixed-length arithmetic-types written in pure c++ templates. The goal is to provide signed-integer, unsigned-integer, IEEE-754 float-point and fixed-point types, all with specific number of bits. To this moment, only signed-integer and unsigned-integer are completed for little-endain architecture. Any compiler that support c++03 or c++11 can successfully compile MathX. Refer to README for more information. -

Free Vector Math Library
C math functions vectorized for x86_64
The goal is to provide SSE (and eventually AVX) vectorized forms of C math functions. These function calls are the basis of floating point math, and currently prevent gcc from auto-vectorizing most numeric code. I want to fix that by providing vectorized versions. Presently, the library provides vectorized forms for double precision for about half of the standard C math functions. -

FixeEngine
A 3D rendering / entity engine
This engine is not an attemp to re-inventing the wheel. It is a more learning-oriented project than something intended to provide a wide set of features. The approach to the OpenGL in this engine is something very experimental born from my own thoughts and can be usefull in future. If you want to help for your portfolio just ask: the TODO list is very long :) -
