Kajiya
Kajiya ist eine physikalisch basierte Rendering-Engine und ein Echtzeit-Renderer für globale Beleuchtung. Er nutzt einen GPU-beschleunigten Path-Tracer, um reale Materialeigenschaften wie Rauheit und Metallizität zu simulieren und fotorealistische visuelle Ergebnisse zu erzielen.
Die Engine integriert einen temporalen Super-Resolution-Upscaler, um die finale Renderauflösung durch Rekonstruktion von Bildern aus internen Frames mit niedrigerer Auflösung zu erhöhen. Zudem generiert sie hochauflösende Referenzbilder mittels Path-Tracing, um die visuelle Genauigkeit der Echtzeit-Beleuchtungsergebnisse zu verifizieren.
Das System deckt die 3D-Szenenvisualisierung und das Asset-Management ab, einschließlich des Imports von Meshes und Szenenkonfigurationen. Es unterstützt zudem bildbasierte Beleuchtung (Image-Based Lighting) unter Verwendung von HDR-Bildern, um eine realistische Umgebungsbeleuchtung zu gewährleisten.
