You could perhaps try to make the half-triangles into full triangles, but let half of the triangle fall outside of the viewbox of the pattern. That way the fill will look the same as for a full triangle, and hopefull pair up with the next tile. > What I want to do is to create something identical to > http://srufaculty.sru.edu/david.dailey/svg/triangles4.svg but with > <pattern> instead of DOM.

My guess is that if you have a large area to tile on then using patterns will be faster than having the same thing drawn a number of times. If you're not tiling a large area then sometimes it's faster to draw the same thing repeatedly (like in your scripted version).
