Ion
Portable suite of libraries and tools for building client applications
Ion is a modular C++ toolkit for building high-performance 2D/3D graphics applications with a strong emphasis on portability, correctness, and developer ergonomics. Rather than a monolithic engine, it offers focused libraries—math, image, GPU resource management, shader utilities, remote inspection, and platform abstractions—that you can adopt à la carte. The rendering layer wraps modern OpenGL/OpenGL ES concepts with a carefully layered API that tracks object lifetimes, deduplicates resources, and enables safe multithreaded recording of draw calls. Asset utilities handle image formats, texture compression, and color management so pipelines can stay consistent across desktop and mobile GPUs. ...
