This software +_C_ was created using the OpenGL(R) version 1.2.1 Sample Implementation +_C_ published by SGI, but has not been independently verified as being +_C_ compliant with the OpenGL(R) version 1.2.1 Specification. +_C_ +_C_ The first character in this file must be an '_'! +_C_ Anything on a line after _C_ is ignored +_header(CallLists,execute a list of display lists) +_names(CallLists) +.SH PARAMETERS +_phead(_param1) +Specifies the number of display lists to be executed. +_phead(_param2) +Specifies the type of values in _param3. +Symbolic constants +_const(BYTE), +_const(UNSIGNED_BYTE), +_const(SHORT), +_const(UNSIGNED_SHORT), +_const(INT), +_const(UNSIGNED_INT), +_const(FLOAT), +_const(2_BYTES), +_const(3_BYTES), and +_const(4_BYTES) are accepted. +_phead(_param3) +Specifies the address of an array of name offsets in the display list. +The pointer type is void because the offsets can be bytes, +shorts, +ints, +or floats, +depending on the value of _param2. +.SH DESCRIPTION +_cmnd causes each display list in the list of names passed as _param3 +to be executed. +As a result, +the commands saved in each display list are executed in order, +just as if they were called without using a display list. +Names of display lists that have not been defined are ignored. +.P +_cmnd provides an efficient means for executing more than one display list. +_param2 allows lists with various name formats to be accepted. +The formats are as follows: +.TP 25 +_const(BYTE) +_param3 is treated as an array of signed bytes, +each in the range \-128 through 127. +.TP +_const(UNSIGNED_BYTE) +_param3 is treated as an array of unsigned bytes, +each in the range 0 through 255. +.TP +_const(SHORT) +_param3 is treated as an array of signed two-byte integers, +each in the range \-32768 through 32767. +.TP +_const(UNSIGNED_SHORT) +_param3 is treated as an array of unsigned two-byte integers, +each in the range 0 through 65535. +.TP +_const(INT) +_param3 is treated as an array of signed four-byte integers. +.TP +_const(UNSIGNED_INT) +_param3 is treated as an array of unsigned four-byte integers. +.TP +_const(FLOAT) +_param3 is treated as an array of four-byte floating-point values. +.TP +_const(2_BYTES) +_param3 is treated as an array of unsigned bytes. +Each pair of bytes specifies a single display-list name. +The value of the pair is computed as 256 times the unsigned value +of the first byte plus the unsigned value of the second byte. +.TP +_const(3_BYTES) +_param3 is treated as an array of unsigned bytes. +Each triplet of bytes specifies a single display-list name. +The value of the triplet is computed as 65536 times the unsigned value +of the first byte, +plus 256 times the unsigned value of the second byte, +plus the unsigned value of the third byte. +.TP +_const(4_BYTES) +_param3 is treated as an array of unsigned bytes. +Each quadruplet of bytes specifies a single display-list name. +The value of the quadruplet is computed as 16777216 times the unsigned value +of the first byte, +plus 65536 times the unsigned value of the second byte, +plus 256 times the unsigned value of the third byte, +plus the unsigned value of the fourth byte. +.P +The list of display-list names is not null-terminated. +Rather, +_param1 specifies how many names are to be taken from _param3. +.P +An additional level of indirection is made available with the +_cmnd(ListBase) command, +which specifies an unsigned offset that is added to each display-list +name specified in _param3 before that display list is executed. +.P +_cmnd can appear inside a display list. +To avoid the possibility of infinite recursion resulting from display lists +calling one another, +a limit is placed on the nesting level of display +lists during display-list execution. +This limit must be at least 64, and it depends on the implementation. +.P +GL state is not saved and restored across a call to _cmnd. +Thus, +changes made to GL state during the execution of the display lists +remain after execution is completed. +Use _cmnd(PushAttrib), +_cmnd(PopAttrib), +_cmnd(PushMatrix), +and _cmnd(PopMatrix) to preserve GL state across _cmnd calls. +.SH NOTES +Display lists can be executed between a call to _cmnd(Begin) +and the corresponding call to _cmnd(End), +as long as the display list includes only commands that are allowed +in this interval. +.SH ERRORS +_const(INVALID_VALUE) is generated if _param1 is negative. +.P +_const(INVALID_ENUM) is generated if _param2 is not one of +_const(BYTE), +_const(UNSIGNED_BYTE), +_const(SHORT), +_const(UNSIGNED_SHORT), +_const(INT), +_const(UNSIGNED_INT), +_const(FLOAT), +_const(2_BYTES), +_const(3_BYTES), +_const(4_BYTES). +.SH ASSOCIATED GETS +_cmnd(Get) with argument _const(LIST_BASE) +.br +_cmnd(Get) with argument _const(MAX_LIST_NESTING) +.br +_cmnd(IsList) +.SH SEE ALSO +_cmnd(CallList), +_cmnd(DeleteLists), +_cmnd(GenLists), +_cmnd(ListBase), +_cmnd(NewList), +_cmnd(PushAttrib), +.br +_cmnd(PushMatrix) |
