Experts talk about how to use 3D point cloud technology to make the VR experience more realistic

Paul Tice, a veteran in the 3D scanning industry for over two decades, believes that the future of 3D modeling might eventually be replaced by advancements in 3D scanning technology. As the Executive Director of ToPa 3D, a leading 3D visualization and design company, he recently sparked a conversation on LinkedIn about point cloud data used by Australian tech firm Euclideon. Point clouds are generated through 3D scanning devices like the FARO Focus 3D or the Shining 3D Einscan Pro. These systems capture millions of points when scanning an object, which can make managing such massive datasets extremely challenging. While CAD software can process these points, the process is resource-intensive and often time-consuming to refine into a complete model. ToPa 3D has developed a unique infinite detail algorithm within its SOLIDSCAN software, allowing real-time rendering of point clouds for interactive 3D visualization. The algorithm captures just one point per screen pixel, significantly reducing the computational load while maintaining high-quality visuals. Tice’s recent comments have stirred discussions in the industry. He suggested that if Youli (a company known for its point cloud processing) can animate point clouds as demonstrated, it could lead to assigning metadata to each point, enabling them to function as IoT components. This could potentially eliminate traditional component and mesh modeling in the future, with smart models being built entirely from point cloud data. He outlined two potential directions for the "point cloud future": integrating metadata into point clouds and creating intelligent 3D models independent of grids. Metadata attached to point clouds can enhance machine learning and AI applications, especially in augmented reality and virtual reality. For instance, Dassault Systèmes integrated HTC Vive into its 3DEXPERIENCE platform, allowing users to immerse themselves in 3D designs. The concept of an "intelligent 3D model independent of the grid" suggests faster and more reliable 3D visualization. Tice envisioned a 3D landscape where users could zoom in on a single particle in seconds, similar to how Google Earth works but with far greater detail and speed. Imagine a world where LiDAR scans the entire planet in real-time, providing immersive and detailed 3D views. This vision not only excites the tech community but also opens new possibilities for realistic virtual environments. By using sparse point clouds instead of polygons, the system can deliver more accurate visuals while reducing computational strain on devices. Such innovations could revolutionize industries like architecture, engineering, and even space exploration. The idea of walking on the moon through a 3D scan or exploring an entire city in real-time is no longer science fiction—it's becoming a tangible possibility. With continued progress, the future of 3D scanning may indeed reshape how we interact with digital worlds.
