Sharing GIS Technologies, Resources and News.

In today's era of booming real-world 3D technology, OSGB format models are widely used. However, "how to publish efficiently and browse smoothly" has always been a pain point for developers: slow loading, large file sizes, laggy interactions on mobile devices... Even star engines like Cesium struggle with issues such as "bloated architecture and subpar mobile experience." In mid-January this year, Zhongke Tuxin open-sourced a lightweight real-world 3D model publishing engine — Wish3D. It claims to be free and open-source, accessible for both individuals and enterprises without barriers. The editor saw it in the MalagiGIS group yesterday and immediately downloaded it for a test drive. Overall, it's indeed fast, but there are several minor issues. Let's share the experience today.

In recent years, applications such as digital museums, digital cultural heritage preservation, and digital scenic spots have become commonplace online. The 3D reconstruction technology behind them impresses with its stunning visual appeal—using just a screen, it can deliver an immersive experience. Nowadays, this kind of immersive virtual experience has permeated various industries. For example, in the popular game Black Myth: Wukong, the "Little Western Paradise" scene was created by capturing and reconstructing the Thousand-Buddha Cliffside Temple (Qianfo'an) in Xi County, Linfen, Shanxi Province. Similarly, Assassin's Creed: Unity used 3D technology to recreate the majestic Notre-Dame de Paris, achieving a remarkable synergy between the virtual and the real.

Recently, while testing OSGB data and related software, I explored using ArcGIS Pro for this purpose. After successful verification, this article documents the specific workflow.

Required Tools

1. ArcGIS Pro 3.0/3.1 (Other versions & ArcMap untested)
2. Sample oblique photography dataset
