Filament

Prioritizes small binary size and high performance, especially on Android, as emphasized in the philosophy, making it ideal for resource-constrained mobile applications.

Implements clustered forward rendering, Cook-Torrance BRDF, and supports complex materials like clear coat and subsurface scattering, enabling realistic lighting and materials out of the box.

Renders via OpenGL, Vulkan, Metal, WebGPU, and WebGL 2.0, ensuring broad compatibility across Android, iOS, desktop, and web platforms, as listed in the features.

Includes tools like matc for runtime material compilation and cmgen for image-based lighting generation, facilitating a robust asset pipeline, though version matching is required.
