GLCLIENTACTIVETEXTUR(3G) OpenGL Manual GLCLIENTACTIVETEXTUR(3G)
NAME
glClientActiveTexture - select active texture unit
C SPECIFICATION
void glClientActiveTexture(GLenum texture);
PARAMETERS
texture
Specifies which texture unit to make active. The number of texture units is implementation dependent, but must be at least two.
texture must be one of GL_TEXTUREi, where i ranges from 0 to the value of GL_MAX_TEXTURE_COORDS - 1, which is an
implementation-dependent value. The initial value is GL_TEXTURE0.
DESCRIPTION
glClientActiveTexture selects the vertex array client state parameters to be modified by glTexCoordPointer(), and enabled or disabled with
glEnableClientState() or glDisableClientState(), respectively, when called with a parameter of GL_TEXTURE_COORD_ARRAY.
NOTES
glClientActiveTexture is supported only if the GL version is 1.3 or greater, or ARB_multitexture is included in the string returned by
glGetString() when called with the argument GL_EXTENSIONS.
ERRORS
GL_INVALID_ENUM is generated if texture is not one of GL_TEXTUREi, where i ranges from 0 to the value of GL_MAX_TEXTURE_COORDS - 1.
ASSOCIATED GETS
glGet() with argument GL_CLIENT_ACTIVE_TEXTURE or GL_MAX_TEXTURE_COORDS
