Q:

Vector graphics in LaTeX

I need to add some vector graphics to my LaTeX files. I would like to end up with good looking wireframes, such as in Hatcher's book "Algebraic Topology" (for an example take a look here). Which tools would you recommend? Any help would be appreciated, thanks in advance.
EDIT: The best thing would be to use an external tool, such as a 3d editor (just a simple one, which lets you easily model a 3d mesh from scratch) and then export the wireframe as a vector image. I don't know if something like this could exist. Tools like tikz or pstricks could do the job, but they are mainly suitable for flat drawings, and require more effort for 3d (drawing something like this could be very tedious).

A:

You can use tikz or pstricks to draw diagrams from within a LaTeX document. Diagram drawing software capable of creating eps or pdf files (e.g. xfig (free) or Adobe Illustrator) will also yield good results.
For examples using TikZ (including 3D), see here.

A:

Ipe is another drawing program you may want to consider.  It has very nice TeX integration.  Inkscape is yet another option; see this.
