glTF Scene with Effects

This example demonstrates loading a glTF scene in ossia score with post-processing shader effects and audio-reactive camera animation.

Overview

Using Qt Quick 3D integration, this example loads the A Beautiful Game glTF chess set model and renders it with PBR materials, reflection probes, environment mapping, and dynamic lighting. The camera is controllable through mouse and WASD, while post-processing effects such as bloom, color blowout, and optical flow distortion are applied on top.

Key concepts

  • glTF loading: The Object loader node loads a .glb file at runtime, supporting full PBR materials and scene hierarchies.
  • Environment mapping: An HDR environment map (.exr) provides realistic reflections and ambient lighting via a light probe.
  • Post-processing effects: Bloom, color blowout, and optical flow distortion shaders are chained as post-processing passes on the rendered scene.
  • Audio integration: An audio input is analyzed with a peak detector, allowing visual parameters to react to sound levels.
