Fig 2. Overview of the workflow using a specimen of a rufous-winged tanager (Tangara lavinia), MLZ:Bird:8631.

(a) Physical set-up shown in Fig 1; (b) One of 288 pre-processed RAW photos taken during the subject's rotation on the turntable; (c) Image processing using color chart to standardize lighting and color; (d) Image registration (alignment) where the 3D point cloud is surrounded by aligned camera locations, shown as blue rectangles (only two angles shown); (e) The 3D mesh generation from the point cloud includes extraneous detail, such as the scale bar, which can be removed after scale calibration; (f) Surface topology (shown in wireframe) optimized and UV coordinates (right) mapped onto the model; (g) Import into image registration software to add texture from the aligned photos, using UV coordinates (right).
