glEnableVertexAttribArray
glDisableVertexAttribArray
Enable or disable a generic vertex attribute array
C Specification
void glEnableVertexAttribArray
GLuint index
void glDisableVertexAttribArray
GLuint index
Parameters
index
Specifies the index of the generic vertex
attribute to be enabled or disabled.
Description
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.
Notes
glEnableVertexAttribArray and
glDisableVertexAttribArray are available
only if the GL version is 2.0 or greater.
Errors
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.
