_header(MultiTexCoordARB, set the current texture coordinates)
38
_names(MultiTexCoord,[1-4]u*[sifdb]ARB)
44
Specifies texture unit whose coordinates should be modified. The number
45
of texture units is implementation dependent, but must be at least
46
two. Must be one of _arbconstidx(TEXTURE) where 0 \(<= $ i $ <
47
_arbconst(MAX_TEXTURE_UNITS), which is an implementation-dependent value.
48
_phead(_param2 _param3 _param4 _param5)
49
Specify _param2, _param3, _param4, and _param5 texture coordinates for
50
_param1 texture unit. Not all parameters are present in all forms
52
_names(MultiTexCoord,[1-4]u*[sifdb]vARB)
55
Specifies texture unit whose coordinates should be modified. The number
56
of texture units is implementation dependent, but must be at least
57
two. Must be one of _arbconstidx(TEXTURE),
58
where 0 \(<= $ i $ < the implementation-dependent value of
59
_const(MAX_TEXTURE_UNITS_ARB).
61
Specifies a pointer to an array of one, two, three, or four elements,
62
which in turn specify the _param2(1), _param3(1), _param4(1),
63
and _param5(1) texture coordinates.
65
_cmnd specifies texture coordinates in one, two, three, or four
67
_cmnd(MultiTexCoord1ARB) sets the current texture
68
coordinates to (_param2(1),\ 0,\ 0,\ 1);
69
a call to _cmnd(MultiTexCoord2ARB)
70
sets them to (_param2(1),\ _param3(1),\ 0,\ 1).
71
Similarly, _cmnd(MultiTexCoord3ARB) specifies the texture coordinates as
72
(_param2(1),\ _param3(1),\ _param4(1),\ 1), and
73
_cmnd(MultiTexCoord4ARB)
74
defines all four components explicitly as
75
(_param2(1),\ _param3(1),\ _param4(1),\ _param5(1)).
77
The current texture coordinates are part of the data
78
that is associated with each vertex and with the current
80
Initially, the values for
81
_param2(1), _param3(1), _param4(1), _param5(1) are (0,\ 0,\ 0,\ 1).
84
_cmnd is only supported if _arbstring(multitexture) is included in the
85
string returned by _cmnd(GetString) when called with the argument
88
The current texture coordinates can be updated at any time.
90
_cmnd can be called between a call to _cmnd(Begin) and the corresponding
93
It is always the case that _arbconstidx(TEXTURE) = _arbconst(TEXTURE0) + $i$.

_cmnd(Get) with argument _const(CURRENT_TEXTURE_COORDS) with appropriate
