getHeader

protected java.lang.String getHeader()

Description copied from class: SLBackend

Returns the String that will be included at the top of the resulting shader code. This method is called after the entire program has been scanned, so it provides a way for a subclass to customize the header (for example, to include declarations for "special" variables such as pos1 based on whether they were referenced somewhere in the JSL code). The default implementation returns an empty string, but subclasses may override this to provide different behavior.

Overrides:

getHeader in class GLSLBackend
