libsst / ZEngine

Version 0.6.0 | 762 Studios | WTFPL v2

A cross-platform C++ game engine library providing low-level system abstractions, math, networking, rendering, and an entity-component simulation framework. Originally developed circa 2011-2013.

Modules

Low-level C libraries (libsst-*)

Module	Description
libsst-atomic	Atomic operations for lock-free programming
libsst-concurrency	Threads, mutexes, events, semaphores, read-write locks, TLS
libsst-crypto	Hash functions and cryptographic utilities
libsst-glapi	OpenGL 3.3 context management and function loading
libsst-math	Vectors (2/3/4), matrices (2x2/3x3/4x4), geometry, transforms
libsst-net	Cross-platform socket abstraction (TCP/UDP)
libsst-os	File I/O, memory mapping, dynamic libraries, timing, CPU info
libsst-random	Mersenne Twister, CMWC, small PRNG, simplex noise
libsst-wm	Window creation, input events, OpenGL context, display modes

High-level C++ libraries

Module	Description
ZUtil	RAII wrappers around libsst, custom containers (ZArray, ZList, ZHashMap, ZRingBuffer, ZString), smart pointers, serialization (JSON, XML, INI, binary), logging, slab allocation, task streams
ZNet	Client/server networking built on enet with packet channels, bandwidth metering, and peer management
ZRenderer	OpenGL rendering abstraction: shaders, textures, data buffers, render targets, render state
ZRendererUtil	Font rendering, particle systems, static mesh loading (assimp), tessellation, camera, transform hierarchies
ZSimulation	Entity-component framework with fixed-timestep updates, entity messaging, property buffers, and network synchronization
