Input needed on printing the planets in a 3D printer...
It's in a way a complicated tricky thing, at least for an amateur on a
shoestring budget. Could be broken up into the following list of "things to do": 1. Aquiring topographic data for planet in question (how?/where?). Perhaps it is necessary to scan it from an atlas? (which one?) 2. Turning it into a spheroid (if it isn't already in that format). 3. Increasing surface elevation/decreasing depressions 50 or 100 times. (program to use?) 4. Aquiring "surface colour data" (a picture in visible light of the surface) for planet in question (how?/where?) Some atlas could have quality pictures (which one?). 5. Turning that data into a spheroid (if it isn't already in that format) 6. Perhaps processing "surface colour data" so it's "aestetically pleasing" and "easy to see" 7. Merging colour picture and topographic data 8. Actually printing the planet on a 3D printer (what brand of printer?; cost of a "print"?) I have been thinking of starting with our own moon. Could google moon be a shortcut somehow? The most important thing is perhaps learning to use and tweak some 3D program. Or some cartographic program. All input welcome! http://cseligman.com/text/moons/moonmap.htm ---here you can find a colour coded topographic map of the moon. But how do you get it into a 3D program? DK |

The Wavefront OBJ file format is pretty easy to understand. If this were my project I would write a program to create a sphere in that file format, then map the coordinates from a jpg image onto the sphere. Wikipedia has all that you need to decode that file format. Blender and Meshlab are among my favorite free programs for working with meshes. |
