- Started with the idea of trying to 3d print a seifert surface and wrote the freps for it. Didnt quite get the time to put it in a software and render it. Will try that some other time. To complete the project in the time I had, designed a small gyroscope and a stand for it in solidworks. I dont have the print yet to put a picture here. The gyro was pretty easy to design once you know how it works, just made sure I followed the correct tolerances for parts sliding against each other and also not making things too thin. Looking forward to holding and spinning it =)
As far as 3d scanning goes, I tried scanning this sea shell I got from Vishakhapatnam, India.
I placed it on a target bag which is patterned and took multiple pictures of it with my phone. I was dubious of this method, so just to be safe I printed a chess pattern on paper and did the same on the chess pattern. 123D Catch results were totally opposite to what I thought. The pictures I took on the chess pattern didnt quite give me as good a result as that on the target bag! I think it has to be just the angle at which I held my camera and has nothing to do with what pattern I chose in the bg, but who knows! I need more data points to prove my theory. This is what the scan looks like. Needs refining to come to printing level
