Tetrahedra require the following parameters, typically formatted as follows:

BaseLength<spc>TopLength<spc>Height<spc>XOffset<spc>YOffset<nl>

where BaseLength is a double defining the side length of the base equilateral triangle, TopLength is a double defining the side length of the top equilateral triangle, Height is a double defining the distance, measured along the local Z-axis, between the base and the top of the tetrahedron, XOffset is a double containing an offset from the X-axis local origin for the top of the tetrahedron, YOffset is a double containing an offset from the Y-axis local origin for the top of the tetrahedron, <spc> is the space character and <nl> is the newline sequence.

Tetrahedra are drawn with their base on the local X-Y plane, with the cell origin used as the center of the base, and each tetrahedron extending up along the local Z-axis.
