asymptote: grid3

 
 8.32 'grid3'
 ============
 
 This module, contributed by Philippe Ivaldi, can be used for drawing 3D
 grids.  Here is an example (further examples can be found in 'grid3.asy'
 and at <http://www.piprime.fr/files/asymptote/grid3/>):
 import grid3;
 
 size(8cm,0,IgnoreAspect);
 currentprojection=orthographic(0.5,1,0.5);
 
 scale(Linear, Linear, Log);
 
 limits((-2,-2,1),(0,2,100));
 
 grid3(XYZgrid);
 
 xaxis3(Label("$x$",position=EndPoint,align=S),Bounds(Min,Min),
        OutTicks());
 yaxis3(Label("$y$",position=EndPoint,align=S),Bounds(Min,Min),OutTicks());
 zaxis3(Label("$z$",position=EndPoint,align=(-1,0.5)),Bounds(Min,Min),
        OutTicks(beginlabel=false));
