Each 3D data begins with a character '/' (slash). For example, a box is described as:
/Box 0.5 0.5 0.5
where the 0.5's are half lengths of edges. On the other hand, each rendering command for DAWN begins with a character '!' (exclamation mark). For example,
!DrawAll
is a command to request DAWN to flush drawing. Each 3D data and rendering command need not begin at the first column of the line, i.e., indentation is allowed.
