Detailed Description

Returns a Display casacore::List Element for recording GL commands.

Synopsis

Returns a Display casacore::List Element for recording GL commands. Commands are recorded until stop is called by creating an OpenGL display list and letting OpenGL do the actual recording. Calling stop ends the list. Typically, these OpenGL lists are very short, containing just one or two commands. eg. draw a rectangle.

Member Function Documentation

virtual void casa::GLPCDisplayListEntry::call ( casacore::Bool  force, const casacore::uInt  nspaces  )

virtual

Draw element unless disabled or force is true.

Reimplemented from casa::GLPCDisplayListElement.

virtual void casa::GLPCDisplayListEntry::start ( )

virtual

Begin recording commands.

Recording is a one shot deal. After stop is called, recording can not be reenabled.

Reimplemented from casa::GLPCDisplayListElement.

virtual void casa::GLPCDisplayListEntry::stop ( )

virtual

Stop display list recording.

Ignored if not already recording.

Reimplemented from casa::GLPCDisplayListElement.
