mFISHSKY

mFISHSKY is a cross-disciplinary open-source software framework designed for realistic sky rendering and atmospheric visualization. It provides a physically based sky model, sun and moon positioning, and an atmospheric scattering pipeline intended for real-time applications as well as offline rendering. The project aims to unify radiative transfer calculations with accessible tooling for developers, researchers, and digital artists.

Origin and governance: The project arises from a collaborative effort among researchers and practitioners in computer

Architecture and core modules: The framework comprises a sky model module, an atmospheric scattering module, a

Features and capabilities: Real-time sky and sun shading, twilight and dawn variants, turbidity and aerosol scattering

Impact and reception: In user communities, mFISHSKY is valued for visual fidelity and flexible integration but
