S1. The imaging approach for photogrammetry. Specimens were mounted and placed in front of black felt backdrop (A). Setup for photographing liver specimen. Images were imported into 3D software (Agisoft Metashape Photoscan Professional, version 1.4.4) and 3D reconstructed models of liver (B) and posterior abdominal wall (C) were visualized. Blue squares depict angle and positioning from which each photograph was taken. Before imaging, specimens were patted dry using paper towels to minimize reflection. Each specimen was slowly rotated 360 degrees while images were taken using Nikon Coolpix P520 and Sony ILCE-5100. The tripod was adjusted to allow images to be taken from several vertical levels. A total of 299 photographs were taken of the PAW specimen and 186 of the liver. Images were downloaded onto a secured computer and imported into Agisoft Metashape Photoscan Professional (version 1.4.4). The photographs were aligned to create a “sparse point cloud” which was then developed into a “dense point cloud prototype.” A mesh was built on this to create the foundation, and digital texture was added to create the final model.
S2. The imaging approach for 360-degree photography. Setup for photographing potted pathology specimens. Specimens were placed on a turntable in front of black felt backdrop and imaged at 17-degree intervals (A). Images were inserted into PowerPoint and image backgrounds were removed using the remove background function (B). The slideshow was looped continuously to give the appearance of the specimen rotating.
