6.1  Language Basics

The POV-Ray language consists of identifiers, reserved keywords, floating point expressions, strings, special symbols and comments. The text of a POV-Ray scene file is free format. You may put statements on separate lines or on the same line as you desire. You may add blank lines, spaces or indentations as long as you do not split any keywords or identifiers.
