PARAMETERS
index Specifies id for new vertex attribute.
DESCRIPTION
glVertexAttribARB sets the values for a generic vertex
attribute. Generic vertex attributes are values associated with
a vertex that are in addition to the standard vertex attributes
(color, normal, texture coordinates etc.).
Generic vertex attributes are stored as an array of 4 component vec‐
tors. The index parameter indicates which vector in the array is being
updated. The first element in the array is number 0 and the size of the
array is specified by GL_MAX_VERTEX_ATTRIBS_ARB.
A 1,2,3 or 4 in the name of the glVertexAttribARB indicates if 1,2,3 or
4 components of the vector will be updated. The default values for the
vectors are (0,0,0,1).
A v in the name specifies a pointer to an array that contains attribute
values. A f, s, d, i, ub, us, ui in the name indicates that the type of
the arguements are float, short, double, int, unsigned byte, unsigned
short, or unsigned int. N indicates that the that the arguements will
be passed as fixed point values scaled to a normalized ranged defined
by OpenGL's component conversion rules.
When v is appended to the name, the commands can take a pointer to an
array of such values.
NOTES
Vertex attributes can be aliased by binding more than one attribute
name to the same vertex attribute index. Aliasing is only allowed when
just one of the aliased attributes is active in the vertx shader of if
the vertex shader does not consume more than one attribute aliased to
the same location.
Vertex attributes can be updated at any time. In particular, glVertex‐
AttribARB can be called between a call to glBegin and the corresponding
call to glEnd.
ERRORS
GL_INVALID_VALUE is generated if either index greater than or equal to
GL_MAX_VERTEX_ATTRIBS_ARB.
