Stars: 225

SPEAR is a Simulator for Photorealistic Embodied AI Research that addresses limitations in existing simulators by offering 300 unique virtual indoor environments with detailed geometry, photorealistic materials, and unique floor plans. It provides an OpenAI Gym interface for interaction via Python, released under an MIT License. The simulator was developed with support from the Intelligent Systems Lab at Intel and Kujiale.
README:
Interactive simulators are becoming powerful tools for training embodied agents, but existing simulators suffer from limited content diversity, physical interactivity, and visual fidelity. We address these limitations by introducing SPEAR: A Simulator for Photorealistic Embodied AI Research. To create our simulator, we worked closely with a team of professional artists for over a year to construct 300 unique virtual indoor environments with 2,566 unique rooms and 17,234 unique objects that can be manipulated individually. Each of our environments features detailed geometry, photorealistic materials, and a unique floor plan and object layout designed by a professional artist, i.e., we do not rely on remixing existing layouts to create additional content. Our environments are implemented as Unreal Engine assets, and we provide an OpenAI Gym interface for interacting with the environments via Python.
The SPEAR code is released under an MIT License, and the SPEAR assets are released under various licenses that permit academic use.
