NAME fglNewList, fglEndList - create or replace a display list FORTRAN SPECIFICATION SUBROUTINE fglNewList( INTEGER*4 list, INTEGER*4 mode ) PARAMETERS list Specifies the display-list name. mode Specifies the compilation mode, which can be GL_COMPILE or GL_COMPILE_AND_EXECUTE. FORTRAN SPECIFICATION SUBROUTINE fglEndList( ) DESCRIPTION Display lists are groups of GL commands that have been stored for subsequent execution. Display lists are created with fglNewList. All subsequent commands are placed in the display list, in the order issued, until fglEndList is called. fglNewList has two arguments. The first argument, list, is a positive integer that becomes the unique name for the display list. Names can be created and reserved with fglGenLists and tested for uniqueness with fglIsList. The second argument, mode, is a symbolic constant that can assume one of two values: GL_COMPILE Commands are merely compiled. GL_COMPILE_AND_EXECUTE Commands are executed as they are compiled into the display list. Certain commands are not compiled into the display list but are executed immediately, regardless of the display-list mode. These commands are fglColorPointer, fglDeleteLists, fglDisableClientState, fglEdgeFlagPointer, fglEnableClientState, fglFeedbackBuffer, fglFinish, fglFlush, fglGenLists, fglIndexPointer, fglInterleavedArrays, fglIsEnabled, fglIsList, fglNormalPointer, fglPopClientAttrib, fglPixelStore, fglPushClientAttrib, fglReadPixels, fglRenderMode, fglSelectBuffer, fglTexCoordPointer, fglVertexPointer, and all of the fglGet commands. Similarly, fglTexImage2D and fglTexImage1D are executed immediately and not compiled into the display list when their first argument is GL_PROXY_TEXTURE_2D or GL_PROXY_TEXTURE_1D, respectively. When fglEndList is encountered, the display-list definition is completed by associating the list with the unique name list (specified in the fglNewList command). If a display list with name list already exists, it is replaced only when fglEndList is called. NOTES fglCallList and fglCallLists can be entered into display lists. Commands in the display list or lists executed by fglCallList or fglCallLists are not included in the display list being created, even if the list creation mode is GL_COMPILE_AND_EXECUTE. A display list is just a group of commands and arguments, so errors generated by commands in a display list must be generated when the list is executed. If the list is created in GL_COMPILE mode, errors are not generated until the list is executed. ERRORS GL_INVALID_VALUE is generated if list is 0. GL_INVALID_ENUM is generated if mode is not an accepted value. GL_INVALID_OPERATION is generated if fglEndList is called without a preceding fglNewList, or if fglNewList is called while a display list is being defined. GL_INVALID_OPERATION is generated if fglNewList or fglEndList is executed between the execution of fglBegin and the corresponding execution of fglEnd. GL_OUT_OF_MEMORY is generated if there is insufficient memory to compile the display list. If the GL version is 1.1 or greater, no change is made to the previous contents of the display list, if any, and no other change is made to the GL state. (It is as if no attempt had been made to create the new display list.)
