I am trying to draw a simple tetrahedron with the following code (in Asymptote)
size(10cm,0); import math; import three; import graph3; currentprojection=perspective(1/3,-1,1/2); real l2=sqrt(0.75); triple x1=(0,0,0), x2=(1,0,0), x3=(0.5,l2,0); draw(x1--x2--x3--cycle); label("$x_1$",x1,W); label("$x_2$",x2,E); label("$x_3$",x3,NW); dot(x1);dot(x2);dot(x3); triple b3=(0.5,l2/2,0); dot(b3,red); label("$B_3$",b3,S,red); real l3=sqrt( (5+4*l2*l2)/9 ); triple x4=(0.5,l2/2,l3); draw(b3--x4,red); label("$x_4$",x4,N,red); draw(x4--x1,dashed); draw(x4--x2,dashed); draw(x4--x3,dashed);
asy tetrahedron.asy gives me an
eps image in which the line
x1--x2 is dashed for some reason, and compiling with
asy tetrahedron.asy -tex pdflatex gives me a blank image.
tex.SE doesn't allow me to upload images in either format, but I can share them with any other tool that users may request. Just post a comment with the tool I should use.
Any help would be greatly appreciated, to understand why I'm getting these errors, and/or how I could fix my script.
