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).
