Abstract

Photogrammetry is transforming digital content creation by enabling the rapid conversion of real-world objects into highly detailed 3D models. This paper evaluates the role of RealityCapture, a GPU-accelerated photogrammetry tool, in game development of Virtual Reality (VR). We assess its efficiency, reconstruction accuracy, and integration with Unreal Engine, comparing its advantages and limitations against traditional modeling workflows. Additionally, we examined user preferences between designed 3D assets and photogrammetry-generated models. The results revealed that while photogrammetry enhances realism and interactivity, users slightly preferred manually designed models for small, manipulable elements because of the level of detail. However, from a developer perspective, RealityCapture significantly reduces development time while maintaining geometric precision and photorealistic textures. Despite its reliance on high-performance hardware, its automation, scalability, and seamless integration with real-time rendering engines make it a valuable tool for game developers and VR creators. Future improvements in AI-driven optimization and cloud-based processing could enhance accessibility, broadening its applications in gaming, cultural heritage preservation, and simulation.
