<p>This is a photogrammetry scan of the bust of Yuri Gagarin, the first man in space. The original sculpture was created by <a href="https://ru.wikipedia.org/wiki/%D0%9B%D0%B5%D0%BE%D0%BD%D0%BE%D0%B2,_%D0%90%D0%BB%D0%B5%D0%BA%D1%81%D0%B5%D0%B9_%D0%94%D0%BC%D0%B8%D1%82%D1%80%D0%B8%D0%B5%D0%B2%D0%B8%D1%87">Aleksey Leonov</a> in 2016 (the sculptor, not the <a href="https://en.wikipedia.org/wiki/Alexei_Leonov">artistic cosmonaut</a>). Bronze castings of this statue can be found all over the world, primarily at parks and educational institutions. More information on the statue can be found at the <a href="https://ethnoworld.ru/en/projects/projects-in-russia/bust-of-yuriy-gagarin/">'Dialogue of Cultures - United World' </a>site.</p><p>Two versions are available, including the bust by itself, as well as one with a partial podium.<br>Both scans are approximately 1:10 in scale.</p><h3>Print Settings</h3><p><strong>Supports:</strong></p><p>Yes</p><h3>How I Designed This</h3><p><strong>Photogrammetry - Taking the photos</strong></p><p>Photos of the statue were taken using a Nikon D7000 camera with a 35-200 mm zoom lens attached to a tripod. I took photos of the statue moving in a series of circles, with the elevation and angle of the camera being adjusted with each complete circle.</p><p>Camera settings were:</p><ul><li>ISO 100 (High quality)</li><li>F-stop number: 32 (for high sharpness)</li><li>Low shutter speed set by camera (to increased light to account for the previous settings)</li><li>2-second self-timer (to reduce camera shake)</li><li>Max zoom (200 mm) because the statue was surrounded by ivy, preventing me from getting close. The scan was done on an overcast day to prevent the movement of shadows.</li></ul><p><strong>Photogrammetry - Processing using Meshroom</strong></p><p>The dataset was put into the free, open-source <a href="https://alicevision.org/#meshroom">Meshroom</a> software and processed without the depth mapping step due to technical issues. It was then decimated to 500,000 vertices and cleaned up in <a href="https://www.blender.org/">Blender</a>. Scale was set by measuring the physical statue's square podium using a ruler and scaling to the same size in Blender. I replaced the podium with a cube of approximately the same size due to defects in the scan.</p>
