| 2019-03-06 11:00:08 +0100 | asked a question | subset of sphere defined by inequalities I need to draw several geodesics on a subset of a unit sphere, namely the set of all points with z-coordinate -0.5<z<0.5< p=""> 1)How do I define the object? A = sphere((0,0,0), 1) How to cut off the domain that i need? I'm a complete novice and failed to find the answer in the documentation. 2) What's the right way to draw a segment of a big circle between two points on a sphere given in spherical coordinates? |
