glEnableVertexAttribArray — Enable or disable a generic vertex attribute array
void glEnableVertexAttribArray( | GLuint | index) ; |
void glDisableVertexAttribArray( | GLuint | index) ; |
glEnableVertexAttribArray
enables the
generic vertex attribute array specified by
index
.
glDisableVertexAttribArray
disables the
generic vertex attribute array specified by
index
. By default, all client-side
capabilities are disabled, including all generic vertex
attribute arrays. If enabled, the values in the generic vertex
attribute array will be accessed and used for rendering when
calls are made to vertex array commands such as
glDrawArrays,
glDrawElements,
glDrawRangeElements,
glArrayElement,
glMultiDrawElements,
or
glMultiDrawArrays.
glEnableVertexAttribArray
and
glDisableVertexAttribArray
are available
only if the GL version is 2.0 or greater.
GL_INVALID_VALUE
is generated if
index
is greater than or equal to
GL_MAX_VERTEX_ATTRIBS
.
GL_INVALID_OPERATION
is generated if either
glEnableVertexAttribArray
or
glDisableVertexAttribArray
is executed
between the execution of
glBegin
and the corresponding execution of
glEnd.
