The initial value is _const(FLOAT). +_phead(_param2) +Specifies the byte offset between consecutive normals. If _param2 is 0\- +the initial value\-the normals are understood to be tightly packed in +the array. +The initial value is 0. +_phead(_param3) +Specifies a pointer to the first coordinate of the first normal in the +array. +The initial value is 0. +.SH DESCRIPTION +_cmnd specifies the location and data format of an array of normals +to use when rendering. +_param1 specifies the data type of +the normal coordinates and _param2 gives the byte stride from one +normal to the next, allowing vertices and attributes +to be packed into a single array or stored in separate arrays. +(Single-array storage may be more efficient on some implementations; +see _cmnd(InterleavedArrays).) +When a normal array is specified, _param1, _param2, and _param3 are +saved as client-side state. +.P +To enable and disable the normal array, call _cmnd(EnableClientState) and +_cmnd(DisableClientState) with the argument _const(NORMAL_ARRAY). If +enabled, the normal array is used +when _cmnd(DrawArrays), _cmnd(DrawElements), or _cmnd(ArrayElement) is called. +.P +Use _cmnd(DrawArrays) to construct a sequence of primitives (all of the +same type) from prespecified vertex and vertex attribute arrays. +Use _cmnd(ArrayElement) to specify primitives +by indexing vertices and vertex attributes and _cmnd(DrawElements) to +construct a sequence of primitives by indexing vertices and vertex attributes. +.SH NOTES +_cmnd is available only if the GL version is 1.1 or greater. +.P +The normal array is initially disabled and isn't accessed when +_cmnd(ArrayElement), _cmnd(DrawElements), or _cmnd(DrawArrays) is called. +.P +Execution of _cmnd is not allowed between +_cmnd(Begin) and the corresponding _cmnd(End), +but an error may or may not be generated. If an error is not generated, +the operation is undefined. +.P +_cmnd is typically implemented on the client side. +.P +Since the normal array parameters are client-side state, they are not +saved or restored by _cmnd(PushAttrib) and _cmnd(PopAttrib). +Use _cmnd(PushClientAttrib) and +_cmnd(PopClientAttrib) instead. +.SH ERRORS +_const(INVALID_ENUM) is generated if _param1 is not an accepted value. +.P +_const(INVALID_VALUE) is generated if _param2 is negative. +.SH ASSOCIATED GETS +_cmnd(IsEnabled) with argument _const(NORMAL_ARRAY) +.br +_cmnd(Get) with argument _const(NORMAL_ARRAY_TYPE) +.br +_cmnd(Get) with argument _const(NORMAL_ARRAY_STRIDE) +.br +_cmnd(GetPointerv) with argument _const(NORMAL_ARRAY_POINTER) +.SH SEE ALSO +_C_ no queries or gets listed above, +_C_ alphabetize commands +_C_ seperate with commas not .br. +_C_ no command appears in the associated gets as well as in SEE ALSO. +_cmnd(ArrayElement), +_cmnd(ColorPointer), +_cmnd(DrawArrays), +_cmnd(DrawElements), +_cmnd(EdgeFlagPointer), +_cmnd(Enable), +_cmnd(GetPointerv), +_cmnd(IndexPointer), +_cmnd(InterleavedArrays), +_cmnd(PopClientAttrib), +_cmnd(PushClientAttrib), +_cmnd(TexCoordPointer), +_cmnd(VertexPointer) |
