{"version":"1.0","type":"rich","title":"Silhouette Primitives","description":"Prototype utility for 3D silhouettes.\r\nIt features:\r\n- Combination of sharp edges and contour for the outline.\r\n- Subdivision for more accurate depth sorting.\r\n- Merging simple transformed primitives into complex shapes.\r\n- Optimized to deal with non-trivial scenes. (Further optimization needed - starting with the subdivision.)\r\n- Precomputes the scene once to improve GIF export times.\r\n\r\nThe principle is: a sphere looks like a disc from all angles, but a cylinder or cube has \"inner outlines\". The outer and inner outlines are calculated separately and combined to achieve this look.","author_name":"llemarie","author_url":"https:\/\/turtletoy.net\/user\/llemarie","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\/334500a2c5.jpg","thumbnail_width":512,"thumbnail_height":512,"html":"<iframe src=\"https:\/\/turtletoy.net\/embed\/334500a2c5\" 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}
