3D可视化铁路高架桥再开发

Under the Tracks - 3D Visualization of a Railway Viaduct Redevelopment (GIS + 3D)Tools used: Blender 4.5 + Cycles Render, QGIS, Affinity Photo, Darktable

The images below present a 3D visualization of a railway viaduct redevelopment, including a road tunnel/underpass beneath an active railway line. The scene was developed using GIS geospatial data and a Digital Elevation Model (DEM), combining spatial analysis with 3D environment creation and post-production.

The main objective was to show the design in its real-world context — with accurate terrain, existing vegetation, surrounding buildings, and the full road layout. Using georeferenced data helped preserve correct scale, alignment, and elevation relationships, resulting in a consistent and technically readable presentation.

Scope of work

- Review and preparation of input materials for building the 3D scene in full site context

- Road surface and proposed traffic layout modeling based on the provided site plan

- Viaduct / bridge elements modeled from engineering drawings (views and cross-sections)

- Railway embankment and terrain modeling, including existing greenery and nearby development

- Materials and texture development for key elements (asphalt, markings, structures, details)

- Scene dressing: vehicles, people, and supporting infrastructure elements

- Lighting setup and iterative test renders for look development

- Delivery of 6 static images, including at least three distinct viewpoints, plus post-production and color grading
