Kerbstone 5, Dowth Hall Passage Tomb (Photo Texture)
Greywacke kerbstone located immediately east of K4 along the southern perimeter of the Dowth Hall Passage Tomb (ME020-098----). Decorated with two pecked motifs on its southern/vertical face. The most westerly motif is a partial (1.5 revolutions), anticlockwise spiral. East of this, there is pecking visible along the edges of a sub-rectangular fracture that removed part of the vertical face. It is…

Произход
- Capture Technology: SfM Photogrammetry using Canon EOS 6D MkII DSLR & 50mm f/1.4 lens, X-Rite colour calibration card, calibrated photogrammetric scale bar. Images captured in Canon RAW format. Capture date - 22/11/2021 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 v1.2 (Alignment Settings: Image overlap - low, Detector sensitivity High, Distortion model - Brown 3). Mesh creation using "High detail" setting. Mesh Processing: Reality Capture v1.2 - High poly mesh cleaned and checked for topological errors. High polygon mesh exported as .obj (25,000,033 polygons). Mesh simplified to 50K polygons and smoothed (Strong, weight 0.1, 10 iterations). Low poly model exported as .obj (49,996 polygons). Texturing: Unwrapping of mesh (3DS Max 2022). Production of primary UVW texture maps (Normal, Ambient Occlusion, Position, Height, Cavity, Curvature) by baking High polygon detail using Marmoset Toolbag v3. 8K Texture - Photo texture (Reality Capture v1.2 - Photo-consistency based).. ; Mesh cleaning; Mesh processing; Mesh simplification (decimation); Photogrammetry; Structure-from-motion (SFM)
