{"version":"1.0","type":"rich","title":"Cubic space division #3","description":"This turtle is a combination of \"Cubic space division\" by Escher and the Droste spiral of \"Print Gallery\" (also by Escher).\n\nNote that I divide by e^(0.05*z) vs the normal divide by z to project the vertices to the screen. This way I make sure the projected grid is a Droste image.\n\n#Droste #polygons #3D #Escher","author_name":"reinder","author_url":"https:\/\/turtletoy.net\/user\/reinder","provider_name":"Turtletoy","provider_url":"https:\/\/turtletoy.net\/","license":{"fullName":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International","shortName":"CC BY-NC-SA 4.0","url":"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/4.0\/"},"thumbnail_url":"https:\/\/turtletoy.net\/thumbnail\/e7a276c605.jpg","thumbnail_width":512,"thumbnail_height":512,"html":"<iframe src=\"https:\/\/turtletoy.net\/embed\/e7a276c605\" width=\"1025px\" height=\"554px\" style=\"max-width: 100%; border: 0\" sandbox=\"allow-scripts allow-top-navigation allow-top-navigation-by-user-activation allow-forms allow-popups allow-same-origin\"><\/iframe>","width":1025,"height":554}
