IHTApark: Multi-detailed 3D Architectural Model for VR Sound Research

IHTApark is a multi-detailed 3D architectural model of a park, specifically designed for sound perception research in virtual reality. It integrates visual photogrammetry and acoustic models, with data available separately for visual and acoustic cues at a high level of detail. The dataset includes geometry in FBX format, visual textures in JPEG, and a pre-configured virtual reality scene in Unreal Engine.

Use Cases

• [Studying sound perception in VR] based on [integrated visual and acoustic 3D models]
• [Developing VR architectural walkthroughs] based on [Unreal Engine scene and FBX geometry]
• [Benchmarking acoustic simulation algorithms] based on [high-detail acoustic cue geometries]
• [Researching multi-sensory integration] based on [separately available visual and acoustic data cues]

Strengths

• Dataset is directly linked to a peer-reviewed publication (Front. Built Environ. 7:687237, 2021)
• Provides data in multiple, interoperable formats (FBX, JPEG, Unreal Engine) for different applications
• Model includes both visual and acoustic components, supporting multimodal research

Limitations

• Key metadata such as dataset size, row count, and specific last updated date are unknown across all sources
• The model is described as 'VERSION 1' and includes only modules used for the referenced paper, suggesting it may be incomplete
• Documentation appears focused on usage within Unreal Engine, which may limit accessibility for users of other platforms
