glEnableClientState

Name

glEnableClientState , glDisableClientState - enable or disable client-side capability

C Specification

void glEnableClientState(GLenum array)
void glDisableClientState(GLenum array)

Parameters

array: Specifies the capability to enable or disable. Symbolic constants GL_COLOR_ARRAY, GL_NORMAL_ARRAY, GL_TEXTURE_COORD_ARRAY, and GL_VERTEX_ARRAY are accepted.

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 glDrawArrays, or glDrawElements is called. See glColorPointer.
GL_NORMAL_ARRAY: If enabled, the normal array is enabled for writing and used during rendering when glDrawArrays, or glDrawElements is called. See glNormalPointer.
GL_TEXTURE_COORD_ARRAY: If enabled, the texture coordinate array is enabled for writing and used during rendering when glDrawArrays, or glDrawElements is called. See glTexCoordPointer.
GL_VERTEX_ARRAY: If enabled, the vertex array is enabled for writing and used during rendering when glDrawArrays, or glDrawElements is called. See glVertexPointer.

Notes

Enabling and disabling GL_TEXTURE_COORD_ARRAY affects the active client texture unit. The active client texture unit is controlled with glClientActiveTexture.

Errors

GL_INVALID_ENUM is generated if array is not an accepted value.
