Specifies which texture unit to make active. The number
|
||
|
|
of texture units is implementation dependent, but must be at least
|
||
|
|
two. <parameter>texture</parameter> must be one of

<constant>GL_TEXTURE</constant><inlineequation><mml:math><mml:mi mathvariant="italic">i</mml:mi></mml:math></inlineequation>,

where i ranges from 0 to the value of <constant>GL_MAX_TEXTURE_COORDS</constant> - 1, which is an

implementation-dependent value. The initial value is

<constant>GL_TEXTURE0</constant>.
