3D Multiband Model of the Bikini Venus
Description
The 3D model of the Bikini Venus was obtained using a Multiband Photogrammetric workflow. The mesh model has been topologically optimized by reducing the number of polygons and converting triangles to quads for better implementation on a WEB3D platform. It features customized UV coordinates and includes:
- Three different layers of diffuse texture from various spectral acquisitions (RGB, UVL, and VIS)
- Normal maps generated from the high-density polygonal mesh
- Roughness and metallic maps obtained after processing the diffuse RGB map

The Bikini Venus statue, officially referred to as "Venus in a Bikini" (INV. 152798), is a white marble sculpture depicting the goddess Venus. The statue represents Venus just before her bath, with one hand in the process of unfastening a sandal. Notable features include a golden stróphion that wraps around her breast, crosses her belly, and envelops her hips. The sculpture portrays Venus leaning on a statuette of the god Priapus, while a small wingless putto seated on the ground assists her by holding the sandal with his right hand. The statue is part of the collection at the National Archaeological Museum of Naples (MANN) .

The 3D multiband model of the Bikini Venus was obtained using a comprehensive Multiband Photogrammetric workflow. The process involved several key steps:
- Image Acquisition: High-resolution images were captured using various spectral bands, including RGB, UVL, and VIL. The setup included specialized cameras, filters, and controlled lighting conditions to ensure uniform illumination and minimize shadows.
- Photogrammetric Processing: The images were processed using Structure from Motion (SfM) software to create a detailed 3D model. This involved aligning the images, generating a dense point cloud, and creating a polygonal mesh.
- Topological Optimization: The mesh was optimized by reducing the number of polygons and converting triangles to quads for better implementation in Web3D platforms. Customized UV coordinates were assigned to the model.
- Texture Mapping: Three layers of diffuse textures were applied from the RGB, UVL, and VIL spectral acquisitions. Normal maps were generated from the high-density mesh, and roughness and metallic maps were created from the diffuse RGB maps.
- Integration and Visualization: The different spectral datasets were integrated into a single 3D model using software like Meshlab and 3DF Zephyr. This model was then optimized for interactive experiences on the Web3D platform ATON, allowing for detailed analysis and comparison of the different spectral layers.
