OpenGL 4.2 (Compatibility Profile) - April 27, 2012

2.7. VERTEX SPECIFICATION 32
void VertexP{234}ui(enum type,uint coords);
void VertexP{234}uiv(enum type,const uint *coords);
These commands specify up to four coordinates as described above, packed
into a single natural type as described in section 2.8.1. The type parameter
must be INT_2_10_10_10_REV or UNSIGNED_INT_2_10_10_10_REV, specifying
signed or unsigned data respectively. The first two (x, y), three (x, y, z),
or four (x, y, z, w) components of the packed data are consumed by VertexP2ui,
VertexP3ui, and VertexP4ui, respectively. For VertexP*uiv, coords contains the
address of a single uint containing the packed coordinate components.
A call to any Vertex command specifies four coordinates: x, y, z, and w. The
x coordinate is the first coordinate, y is second, z is third, and w is fourth. A call
to Vertex*2* sets the x and y coordinates; the z coordinate is implicitly set to zero
and the w coordinate to one. Vertex*3* sets x, y, and z to the provided values
and w to one. Vertex*4* sets all four coordinates, allowing the specification of an
arbitrary point in projective three-space. Invoking a Vertex command outside of a
Begin / End pair results in undefined behavior.
Current values are used in associating auxiliary data with a vertex as described
in section 2.5. A current value may be changed at any time by issuing an appropriate
command. The commands
void TexCoord{1234}{sifd}( T coords );
void TexCoord{1234}{sifd}v( const T coords );
specify the current homogeneous texture coordinates, named s, t, r, and q.
Texture coordinates may be stored as packed components within a larger natural
type. Such data may be specified using
void TexCoordP{1234}ui(enum type,uint coords);
void TexCoordP{1234}uiv(enum type,const uint
*coords);
This command specifies up to four components as described above, packed
into a single natural type as described in section 2.8.1. The type parameter
must be INT_2_10_10_10_REV or UNSIGNED_INT_2_10_10_10_REV, specifying
signed or unsigned data, respectively. The first one (x), two (x, y), three
(x, y, z), or four (x, y, z, w) components of the packed data are consumed by Tex-
CoordP1ui*, TexCoordP2ui*, TexCoordP3ui*, and TexCoordP4ui*, respectively.
For TexCoordP*uiv, coords contains the address of a single uint containing
the packed texture coordinate components.
