Sponza Palace

This example demonstrates loading and rendering the Sponza Palace architectural model with PBR materials, environment mapping, and an animated camera.

Overview

The Sponza Palace atrium is a classic test scene in real-time graphics. This example loads a glTF-PBR version of the model using Qt Quick 3D, with an HDR skybox providing realistic ambient lighting and reflections. Three LFOs drive a mathematical expression that smoothly animates the camera look-at target through the scene.

Key concepts

• Architectural glTF scene: The Sponza glTF-PBR model is loaded from a QtQuick 3D script, with full PBR material support.
• HDR environment: A high-dynamic-range .exr environment map is used both as a skybox background and as a light probe for image-based lighting.
• Camera animation: Three LFO processes feed a Math expressions node that outputs animated 3D coordinates, controlling where the camera looks in the scene.
• Interactive navigation: The scene supports real-time WASD keyboard and mouse navigation for free camera control.
