Este proyecto es un wrapper de gráficos multiplataforma y capa de traducción que implementa las especificaciones OpenGL ES y EGL. Funciona como un puente de API de gráficos, mapeando llamadas de OpenGL ES y contenido WebGL a APIs de hardware específicas de la plataforma como Vulkan y Metal para asegurar un renderizado consistente en diferentes sistemas operativos.
El sistema cuenta con un servicio de traducción de shaders que valida el código del lenguaje de sombreado y lo transpila a múltiples lenguajes de destino, incluyendo HLSL, SPIR-V y Metal SL. Emplea una arquitectura de backend conectable para seleccionar la API de renderizado de hardware adecuada durante la inicialización y puede sobrescribir identificadores de hardware de GPU para mantener la compatibilidad de la aplicación.
La superficie de capacidades incluye la abstracción de API de GPU y el mapeo de extensiones de gráficos, así como la traducción de llamadas de cómputo de OpenCL a instrucciones específicas de hardware. Para la gestión de recursos, el proyecto implementa la gestión de buffers de comandos de Vulkan y la sincronización de acceso a recursos utilizando barreras de lectura y escritura.
La observabilidad se proporciona a través de la captura de trazas de llamadas de API, emisión de marcadores de depuración de GPU y registro detallado del sistema para llamadas de la API de Vulkan.
