Functions

These are used for built in functions, but they may also be used for functions/macros defined by the user. They take specific types and numbers of arguments within the parentheses, separated by commas. Some functions may accept named arguments in the form identifier=value.

Examples: sin(pi / 2) cross(vec1, {0,0,1}) my_xform(mesh1) subselect(materials=[a,b])
