N glNewList glNewList glNewList, glEndList: create or replace a display list. C Specification void glNewList( GLuint list, GLenum mode) void glEndList(void) Parameters list mode Specifies the display-list name. Specifies the compilation mode, which can be GL_COMPILE or GL_COMPILE_AND_EXECUTE. Description Display lists are groups of GL commands that have been stored for subsequent execution. Display lists are created with glNewList. All subsequent commands are placed in the display list, in the order issued, until glEndList is called. glNewList 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 glGenLists and tested for uniqueness with glIsList. 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 glColorPointer, glDeleteLists, glDisableClientState, glEdgeFlagPointer, glEnableClientState, glFeedbackBuffer, glFinish, glFlush, glGenLists, glIndexPointer, glInterleavedArrays, glIsEnabled, glIsList, glNormalPointer, glPopClientAttrib, glPixelStore, glPushClientAttrib, glReadPixels, glRenderMode, glSelectBuffer, glTexCoordPointer, glVertexPointer, and all of the glGet commands. Similarly, glTexImage2D and glTexImage1D 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 glEndList is encountered, the display-list definition is completed by associating the list with the unique name list (specified in the glNewList command). If a display list with name list already exists, it is replaced only when glEndList is called. 292 Chapter 12
