But looking back at the source I see this line in Form1.Designer.cs<br /><br />this.nudRadius.Maximum = new decimal(new int[] {<br /> 1000,<br /> 0,<br /> 0,<br /> 0});<br /><br />I would try changing that 1000 to 10000 to suit the sizes you wanted to test. At that size, though, I think the little guy will be very small on the screen!David Kannhttps://www.blogger.com/profile/10744679939853290476noreply@blogger.comtag:blogger.com,1999:blog-5723581430185458400.post-64964882531369227882020-05-23T10:24:12.869-07:002020-05-23T10:24:12.869-07:00Hey awesome little simulator.

What part of the code would I update, I assume its nudsize, but I coulndt see where you maxed it at 1000m.Anonymoushttps://www.blogger.com/profile/18011903499572704967noreply@blogger.comtag:blogger.com,1999:blog-5723581430185458400.post-18607077274597451072018-06-25T15:48:55.825-07:002018-06-25T15:48:55.825-07:00Thanks for sharing, David.

I chose a small default size to emphasize the effect.<br /><br />I would love to see an animation of that waterfall!David Kannhttps://www.blogger.com/profile/17810374492914364419noreply@blogger.comtag:blogger.com,1999:blog-5723581430185458400.post-31492543484189117212016-02-02T05:22:59.562-08:002016-02-02T05:22:59.562-08:00This comment has been removed by the author.Richard Briscoehttps://www.blogger.com/profile/18216534070511692065noreply@blogger.comtag:blogger.com,1999:blog-5723581430185458400.post-76416744424259235962016-02-02T05:22:14.625-08:002016-02-02T05:22:14.625-08:00The effects described are very much related to sca...The effects described are very much related to scale. The animations depict a ball being thrown within a very small cylinder, where the path followed would indeed be very different to that on Earth.<br />Gerard O'Neill (he of the O'Neill cylinder) proposed cylinders of about five miles diameter as suitable space habitats. At this scale, the effects on the motion of a thrown object would be pretty imperceptible. It's worth noting that even on the Earth there are effects due to the Earth's curvature and rotation - they're just too small to notice. <br />It's been observed that one clearly apparent effect of rotation in an O'Neill cylinder would be on waterfalls. A waterfall of any significant height would be visibly curved, even in a five-mile cylinder.Richard Briscoehttps://www.blogger.com/profile/18216534070511692065noreply@blogger.com
