Apr 9	accepted	How to draw a higher-genus surface
Mar 8	comment	How to draw a higher-genus surface Oh wow, the answers on this thread are incredible!
Mar 8	comment	How to draw a higher-genus surface Oh, I wish I could upvote again for the smooth version!
Mar 8	comment	How to draw a higher-genus surface How hard would it be to generalize to higher genus?
Mar 8	comment	How to draw a higher-genus surface This is a quick, nice way to do it. But the "joins" aren't very smooth. :)
Mar 8	comment	How to draw a higher-genus surface I find this slightly ugly; it is not the usual, voluptuous double-torus I know and love. :)
Mar 8	comment	How to draw a higher-genus surface Oh this is pretty!

Feb 27	comment	Showing a rectangular plot on an almost-closed sphere This is great! When I have some time later, I will try it out, making a few slight adjustments (I'd like to watch that visualization from the bottom of the sphere). But thanks again!
Feb 27	comment	Showing a rectangular plot on an almost-closed sphere I mean the stereographic projection of the entire plot, where the points very far away go to the boundary component of this incomplete sphere.So the rectangular axes are projected onto the sphere, along with the plot, along with any gridlines, etc.
Feb 27	comment	Showing a rectangular plot on an almost-closed sphere Great approach! But as I mentioned in a comment above (and now an edit to the question), I want the entire plot (graph, axes, tick marks, etc.) to be on the sphere.

Feb 27	comment	Showing a rectangular plot on an almost-closed sphere This is a great answer, but it is lacking one thing, that might not have been clear from my question: I want the actual axes and everything to be on the surface of the sphere. That is why I added that picture, and why I hinted at using texture.

Feb 26	comment	Showing a rectangular plot on an almost-closed sphere @SimonWoods: I have not gotten a successful result yet; I have only been able to get something "not too bad", using `TextureCoordinateFunction -> ({#5,1-#4} &)`.

Feb 26	comment	Showing a rectangular plot on an almost-closed sphere You can imagine the rectangular plot being stretched over this sphere, so that the boundary is basically infinity in rectangular coordinates. (I don't know if RegionFunction is the right approach, but it is what has worked for me so far.)
Feb 26	comment	Showing a rectangular plot on an almost-closed sphere @belisarius: Here is some sample code: SphericalPlot3D[1, {theta, 0, Pi}, {phi, 0, 3 Pi}, RegionFunction -> (#1 < .8 &), Mesh -> None, Boxed -> False, Axes -> False]
