Gas Mask
3D model of a historic gas mask demonstrating specialised techniques for capturing objects with both rigid and non-rigid components.
This historic gas mask exemplifies the challenges and solutions involved in digitising objects that combine rigid and non-rigid materials, requiring custom approaches to achieve accurate 3D documentation.

About This Object
Gas masks represent a significant category of heritage objects that present unique challenges for 3D capture. The combination of rigid metal or plastic components with flexible rubber or fabric materials requires specialised photogrammetry techniques to preserve the object’s form accurately.
Capture Method
Items with rigid and non-rigid components present special challenges for photogrammetrists, and each requires custom approaches:
- Custom support structure - Built a custom support on a table to hold the mask in position
- Glass mannequin head - Used as an internal support for the mask to maintain its proper shape during photography
- Digital cleanup - The glass mannequin head was removed in the post-processing cleanup stage
- Separate component capture - The bottom of the filter was photographed separately from the main mask
- Expert alignment - The filter component was then aligned to the rest of the assembly
- Advanced masking - Sophisticated masking techniques were employed to seamlessly combine the separately captured components
This multi-stage approach allowed for complete documentation of both the rigid filter housing and the flexible mask material whilst maintaining the object’s authentic form.
Technical Challenges
Objects combining rigid and non-rigid materials require:
- Custom support solutions to maintain proper form
- Careful handling to avoid deformation during capture
- Strategic separation of components for optimal imaging
- Expert post-processing to combine separately captured elements
- Advanced masking and alignment techniques
