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.

DESCRIPTION

       glEnableClientState and glDisableClientState enable or disable individual client-side capabilities. By default, all  client-side  capabili-
       ties  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.

GLTEXCOORDPOINTER(3G)													     GLTEXCOORDPOINTER(3G)

NAME

       glTexCoordPointer - define an array of texture coordinates

C SPECIFICATION

       void glTexCoordPointer( GLint size,
			       GLenum type,
			       GLsizei stride,
			       const GLvoid *pointer )

PARAMETERS

       size	Specifies the number of coordinates per array element. Must be 1, 2, 3 or 4. The initial value is 4.

       type	Specifies the data type of each texture coordinate.  Symbolic constants GL_SHORT, GL_INT, GL_FLOAT, or GL_DOUBLE are accepted. The
		initial value is GL_FLOAT.

       stride	Specifies the byte offset between consecutive array elements.  If stride is 0, the array elements are  understood  to  be  tightly
		packed. The initial value is 0.

       pointer	Specifies a pointer to the first coordinate of the first element in the array.	The initial value is 0.

DESCRIPTION

       glTexCoordPointer  specifies the location and data  of an array of texture coordinates to use when rendering.  size specifies the number of
       coordinates per element, and must be 1, 2, 3, or 4.  type specifies the data type of each texture coordinate and stride specifies the  byte
       stride  from  one array element to the next allowing vertices and attributes to be packed into a single array or stored in separate arrays.
       (Single-array storage may be more efficient on some implementations; see
       glInterleavedArrays.)  When a texture coordinate array is specified, size, type, stride, and pointer are saved client-side state.

       To  enable  and	disable  the  texture  coordinate  array,  call   glEnableClientState	and   glDisableClientState   with   the   argument
       GL_TEXTURE_COORD_ARRAY.	If  enabled,  the  texture  coordinate	array  is  used  when glDrawArrays, glDrawElements, glDrawRangeElements or
       glArrayElement is called.

       Use glDrawArrays to construct a sequence of primitives (all of the same type) from prespecified vertex and vertex  attribute  arrays.   Use
       glArrayElement to specify primitives by indexing vertices and vertex attributes and glDrawElements to construct a sequence of primitives by
       indexing vertices and vertex attributes.

NOTES

       glTexCoordPointer is available only if the GL version is 1.1 or greater.

       The texture coordinate array is initially disabled and it won't be accessed when glArrayElement,  glDrawElements,  glDrawRangeElements,	or
       glDrawArrays is called.

       Execution  of  glTexCoordPointer is not allowed between the execution of glBegin and the corresponding execution of glEnd, but an error may
       or may not be generated. If no error is generated, the operation is undefined.

       glTexCoordPointer is typically implemented on the client side with no protocol.

       The texture coordinate array parameters are client-side state and are therefore not saved or restored by glPushAttrib and glPopAttrib.  Use
       glPushClientAttrib and glPopClientAttrib instead.

       When  the  GL_ARB_imaging extension is supported, glTexCoordPointer updates the texture coordinate array state of the active client texture
       unit, specified with glClientActiveTextureARB.

ERRORS

       GL_INVALID_VALUE is generated if size is not 1, 2, 3, or 4.

       GL_INVALID_ENUM is generated if type is not an accepted value.

       GL_INVALID_VALUE is generated if stride is negative.
