Khronos glTF Viewer vs H2R Graphics Mobile

The Khronos glTF Viewer is an easy-to-use application that lets you view and interact with 3D models in the Khronos glTF 2.0 file format, and includes support for viewing in augmented reality. glTF is the open, industry-standard 3D asset format for the efficient transmission and loading of 3D scenes and models by engines and applications. It is an ISO/IEC International Standard that has become the 3D asset delivery format of choice across the web and real-time applications. Key App Features: • Built-In Sample Models – View sample glTF models showcasing features like physically-based rendering and animation • Object Mode – Rotate, zoom, or pan a 3D model to view it from various angles • AR Mode – Place a 3D model on real-world surfaces with augmented reality • File Browser – Browse and display your own glTF files, including optional integration with iCloud Drive All the features found in the core glTF 2.0 specification are supported, plus a number of glTF extensions, including Physically Based Rendering (PBR) effects such as clearcoat. For a full list of glTF extensions currently supported, please view the GitHub repository.
