svLis-m and SVLIS

svLis-m's representation scheme is similar to that of SVLIS, which makes conversion between the two modellers easy and fast. SVLIS models can be converted into three-dimensional svLis-m models, which can then be extended into more dimensions, whilst svLis-m models with three dimensions or less can be converted into SVLIS models -- this is particularly useful since SVLIS, unlike svLis-m, produces graphical output.
