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.
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, 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.
NOTES
glEnableClientState 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.
