Supplemental Material: Evaluation of field methods for 3-D mapping and 3-D visualization of complex metamorphic structure using multiview stereo terrain models from ground-based photography

Geosphere, February 2019, v. 15, no. 1, p. 188-221, doi:10.1130/GES01691.1, Animation 3. Comparison of major lithologic contacts on the north wall of lower Pleasant Canyon mapped using 2.5-dimensional (2.5-D) methods on a 30 m digital elevation model versus those mapped on the high-resolution MVS model using 3-D methods. Note that this video is meant to be viewed with anaglyph glasses. Yellow and orange lines are lithologic contacts and faults or shear zones, respectively, mapped on an orthophoto. White and blue lines are lithologic contacts and faults or shear zones, respectively, mapped on the 3-D model. These same colors are used for this scene in Figure 13. Note the systematic shifts between the two sets of lines. Of particular note is the poor rendering of the isoclinal fold in the center in the conventional 2.5-D rendering versus the true 3-D rendering. See text for discussion of the origin of the discrepancies. Refer to Figure 3B and 13 for scale. This video was made using Move software.
