I have added several operations and supplemented the help section with corresponding examples:
“union”, “op”, “s” ( op is array [ … ] of operands )
“subtraction” “op”, “s” ( op is array [ … ] of operands, subtraction from first entry )
“rotation” “op”, “rotx”, “roty”, “rotz”, “order”, “quat”, “c” (c is rotation pivot)
“translation” “op”, “c” (c is new center)
The local version will be completed soon.
