This project visualizes gltf scene file with PBR shading techniques. The default lighting is Image-Based-Lighting which precomputes irradiance map and prefiltered glossy map and use them in the PBR shader. Material attributes passing implemented with simple structural uniform variables which can make performance low (This can be improved by ssbo).

git submodule init
git submodule update
mkdir build
cd build
cmake .. && make

# in the generated executable file directory
gl_shaded_gltfscene -s "what_you_want.gltf" -e "hdr_environment.hdr"

Of course, without providing scene and environment files, rendering can be done with default resources.
