Name
glEnableClientState, glDisableClientState — enable or disable client-side capability
C Specification
void glEnableClientState
| ( | GLenum array
); |
Python Specification
glEnableClientState
| ( |
array
) →
None
|
Parameters
-
array
-
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 array
); |
Python Specification
glDisableClientState
| ( |
array
) →
None
|
Parameters
-
array
-
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,
array, 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 array 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.
