Drawing Solids with LaTeX

You might be interested in asymptote, a vector graphics language that you uses TeX for labels and can be used from within LaTeX.

Asymptote can draw standard shapes (spheres, cylinders, cubes, etc) which you can then scale, rotate, and shift to create many other shapes. (Asymptote can also do many other things.)

Here's a brief example.

\documentclass{standalone}
\usepackage{asymptote}

\begin{document}

\begin{asy}
import three;
//Setup View
size(200);
currentprojection=orthographic(5,4,2);

//Draw Axes
pen thickblack = black+0.75;
real axislength = 2.0;
draw(L=Label("$x$", position=Relative(1.1), align=SW), -axislength*X--axislength*X,thickblack, Arrow3); 
draw(L=Label("$y$", position=Relative(1.1), align=E), -axislength*Y--axislength*Y,thickblack, Arrow3); 
draw(L=Label("$z$", position=Relative(1.1), align=N), -2*axislength*Z--2*axislength*Z,thickblack, Arrow3); 

//Define cube surfaces
surface c1 = unitcube;
surface c2 = shift(-2Z)*rotate(45,X)*c1;
surface s1 = unitsphere;
surface s2 = rotate(75,Z)*shift(1.5Z)*xscale3(2)*yscale3(0.5)*zscale3(0.1)*s1;

//Draw cube surfaces
draw(c1,palegrey);
draw(c2,green);
draw(s2,red);
\end{asy}

\end{document}

There is pst-solides3d. The package readme mentions:

The pack­age is de­signed to draw solids in 3D per­spec­tive. Fea­tures in­clude:

• cre­ate prim­i­tive solids;

• cre­ate solids by in­clud­ing a list of its ver­tices and faces;

• faces of solids and sur­faces can be col­ored by choos­ing from a very large palette of col­ors;

• draw para­met­ric sur­faces in al­ge­braic and re­verse pol­ish no­ta­tion;

• cre­ate ex­plicit and pa­ram­e­ter­ized al­ge­braic func­tions drawn in 2 or 3 di­men­sions;

• project text onto a plane and onto the faces of a solid;

• sup­port for in­clud­ing ex­ter­nal database files.

Here's a small example (compile with LaTeX or XeLaTeX):
