- enable or disable client-side capability
C SPECIFICATION
PARAMETERS
_param1 Specifies the capability to enable. Symbolic
constants GL_COLOR_ARRAY, GL_EDGE_FLAG_ARRAY,
GL_INDEX_ARRAY, GL_NORMAL_ARRAY,
GL_TEXTURE_COORD_ARRAY, and GL_VERTEX_ARRAY are
accepted.
C SPECIFICATION
PARAMETERS
_param1
Specifies the capability to disable.
DESCRIPTION
glEnableClientState and glDisableClientState enable or
disable individual client-side capabilities. By default,
all client-side capabilities are disabled. Both
glEnableClientState and glDisableClientState take a single
argument, _param1, which can assume one of the following
values:
GL_COLOR_ARRAY If enabled, the color array is
enabled for writing and used dur-
ing rendering when
glArrayElement, glDrawArrays,
glDrawElement, or
glDrawRangeElements is called.
See glColorPointer.
GL_EDGE_FLAG_ARRAY If enabled, the edge flag array
is enabled for writing and used
during rendering when
glArrayElement, glDrawArrays,
glDrawElement, or
glDrawRangeElements is called.
See glEdgeFlagPointer.
GL_INDEX_ARRAY If enabled, the index array is
enabled for writing and used dur-
ing rendering when
glArrayElement, glDrawArrays,
glDrawElement, or
glDrawRangeElements is called.
See glIndexPointer.
GL_NORMAL_ARRAY If enabled, the normal array is
enabled for writing and used dur-
ing rendering when
glArrayElement, glDrawArrays,
ing rendering when
glArrayElement, glDrawArrays,
glDrawElement, or
glDrawRangeElements is called.
See glVertexPointer.
NOTES
glEnableClientState is available only if the GL version is
1.1 or greater.
If GL_ARB_multitexture is supported, enabling and dis-
abling GL_TEXTURE_COORD_ARRAY affects the active client
texture unit. The active client texture unit is con-
trolled with glClientActiveTextureARB.
ERRORS
GL_INVALID_ENUM is generated if _param1 is not an accepted
value.
glEnableClientState is not allowed between the execution
of glBegin and the corresponding glEnd, but an error may
or may not be generated. If no error is generated, the
behavior is undefined.
