Antler Spearhead/Goad, Knowth
E70:65
This artefact was found at Knowth, Co. Meath, Ireland, but dates to the Iron Age period of activity at the site. It was found in Burial 24, that of a young child, situated by the child’s elbow. It is made of antler and may be a spearhead, or possibly a goad used to drive cattle or other animals. There are three rows of a chevron pattern decorating the base.

Päritolu
- Capture Technology: SfM Photogrammetry using Canon EOS 6D MkII DSLR & Sigma 70mm f/2.8 EX DG Macro - Canon EF Fit (circular polarising filter). Illumination Rotolight Neo 2 x 3 with polarising filter gel, X-Rite colour calibration card, calibrated photogrammetric scale image. Automated rotation using Cognisys Rotary Table and StackShot 3x Controller. Images captured in Canon RAW format. Capture date 27/03/2024 Image Pre Processing: ColorChecker Camera Calibration v2.3.0 & Adobe RAW 14.4 - Generation of calibrated texture images and high contrast SfM alignment images in jpeg format. Photogrammetric processing: Reality Capture v1.4 Alignment Settings: Image overlap - low, Detector sensitivity High, Distortion model - Brown3 with tangential2 . Mesh creation using "High detail" setting. Mesh Processing: Reality Capture v1.4 - High poly mesh cleaned and checked for topological errors. High polygon mesh exported as .obj (33,017,289 polygons). Mesh simplified to 50K polygons and smoothed (Strong, weight 0.1, 10 iterations). Low poly model exported as .obj (49,998 polygons). Texturing: Unwrapping of mesh (3DS Max 2024). Production of primary UVW texture maps (Normal, Ambient Occlusion, Position, Height, Cavity, Curvature) by baking High polygon detail using Marmoset Toolbag v4. 8K Texture - Photo texture (Reality Capture v1.4 - Photo-consistency based). Roughness texture map generated through subtraction between cross polarised & polarised texture images. ; Mesh cleaning; Mesh processing; Mesh simplification (decimation); Photogrammetry; Structure-from-motion (SFM)
