Dear ZongQuan,
Use the 'block' geometric object to define a parallelepiped using the
material you want, then remove the unwanted part with another
parallelepiped with material air. Set their axes by defining e1,e2 and
e3. For example:
(make block (center 0 0 0) (material mat) (size 1 1 1)
(e1 1 1 0) (e2 1 -1 0) (e3 0 0 1))
would make a cube with sides of length 1, that has been rotated 45
degrees. You could 'cut-away' some of the cube to the right (along
x-axis) like this:
(make block (center 1 0 0) (material air) (size 2 1 1)
This would give you a prism. To make an equilateral triangle you will
need to set the directions (vectors) of (e1, e2, e3) accordingly to give
a rhombus, then cut away.

Output the epsilon file and use h5topng to check your geometry.
