BaseBall

 Attached please find parametric script to create a baseball. Based upon equations of Richard Thompson. Only had a few typo bugs to correct, this time. Have not done laces yet. That might take some calculus, or maybe FLOW. Due to the power of MoI, only 1/4 of the seam is needed. (Or is it 1/8th) Just mirror the curve, join, and mirror again. It helps to create a solid sphere of radius 1.45229 inches, to see better. I've got milimeters selected in MoI, but is doesn't seem to matter, just resize. Haven't researched tennis ball yet. After seeing Michaels 6 sided sphere, thought this baseball would be good to try out some FLOW. Can the seems be Un-Flowed? Wikipedia has specifications. Of course, once have the curve, don't need the script anymore? (The next stiching jpg is from the Web.) EDITED: 19 Feb 2014 by BEMFARMER Attachments:

 4553.2 In reply to 4553.1 Just had something weird happen with MoI3. Went to shutdown windows 7. Had not saved baseball in MoI3. Aborted the shutdown, clicked on MoI3 icon, and now have only the 4 quadrant views, no menus, nor icons at all. (Should be fine upon reboot.)

 4553.4 In reply to 4553.1 Hi Brian, another cool one! You asked: > Can the seems be Un-Flowed? Yes, you can flow in the reverse direction, from a curved surface onto a plane instead of the other way around. To do that you just pick the curved surface as the base surface and the plane as the target. I've attached an example - to do it, select the curve then run Transform > Deform > Flow, and pick the sphere as the base surface and the plane as the target - the curve will be applied on to the plane in the same relation it has to the UV space of the sphere. - Michael Attachments:

Hmmm, haven't seen this problem before yet over here. Sounds like something didn't go right with the regular UI loading process. It could be some side effect relating to the aborted system shutdown I guess. Please let me know if you see it again, especially if you see it under normal running circumstances. - Michael

 4553.6 In reply to 4553.4 Hi Brian, also one thing to note about the "reverse flow" is that just like when you flow from a base plane on to a sphere target where there is compression happening at the pole areas of the sphere when you go in the reverse direction the same kind of thing will happen where there is a kind of expansion deformation happening in the unflowed result. It's generally more like texture mapping and not the same as a "developable surface" - the 2D result won't work for example to make a pattern to cut to do a physical construction of the 3D object because of the expansion and compression that is happening. But it still could be useful as a modeling tool - you could do something like unflow it to get a good idea of where in the plane you want to draw some things to then flow back on to the sphere. - Michael

 4553.7 In reply to 4553.6 Thank you Michael. MoI3beta worked great again, after morning computer turnon. The "UnFlow" seems to flow back to the same curve. Red + Blue = Purple.
