## What it is
A Vulkan-based physically-based rendering (PBR) sample application that loads and renders glTF 2.0 models with image-based lighting. It includes a glTF model loader built on tinyglTF and generates required PBR texture maps on the GPU at startup.

## Use cases
- render glTF 2.0 models with physically based rendering in Vulkan
- learn how to implement PBR with image-based lighting
- load and display glTF models with skinned animations
- generate BRDF lookup tables on the GPU
- example of a glTF model loader for Vulkan

## When to choose
- you want a reference implementation of glTF 2.0 PBR rendering in Vulkan
- you're learning Vulkan graphics programming with real-world 3D assets
- you need sample code for metallic-roughness and specular-glossiness workflows

## When to avoid
- you need a production-ready glTF loader covering the full glTF 2.0 standard
- you target OpenGL, DirectX, or Metal instead of Vulkan
- you need morph target animation support, which is not implemented

## Facets
- artifact type: application
