GLENABLECLIENTSTATE(3G)GLENABLECLIENTSTATE(3G)NAME
glEnableClientState, glDisableClientState - enable or disable
client-side capability
C SPECIFICATION
void glEnableClientState( GLenum cap); 1.1 )
PARAMETERS
1.1 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
void glDisableClientState( GLenum cap); 1.1 )
PARAMETERS
1.1 Specifies the capability to disable.
DESCRIPTIONglEnableClientState 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, 1.1, which can assume one
of the following values:
GL_COLOR_ARRAY If enabled, the color array is enabled for
writing and used during 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 during 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 during rendering when
glArrayElement, glDrawArrays, glDrawElement,
or glDrawRangeElements is called. See
glNormalPointer.
GL_TEXTURE_COORD_ARRAY If enabled, the texture coordinate array is
enabled for writing and used during rendering
when glArrayElement, glDrawArrays,
glDrawElement, or glDrawRangeElements is
called. See glTexCoordPointer.
GL_VERTEX_ARRAY If enabled, the vertex array is enabled for
writing and used during rendering when
glArrayElement, glDrawArrays, glDrawElement,
or glDrawRangeElements is called. See
glVertexPointer.
NOTESglEnableClientState is available only if the GL version is 1.1 or
greater.
If GL_ARB_multitexture is supported, enabling and disabling
GL_TEXTURE_COORD_ARRAY affects the active client texture unit. The
active client texture unit is controlled with glClientActiveTextureARB.
ERRORS
GL_INVALID_ENUM is generated if 1.1 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.
