NAME¶
glActiveTexture - select active texture unit
C SPECIFICATION¶
void
glActiveTexture(GLenum texture);
PARAMETERS¶
texture
Specifies which texture unit to make active.
The number of texture units is implementation dependent, but must be at least
80. texture must be one of GL_TEXTUREi, where
i ranges from 0 ( GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS - 1). The
initial value is GL_TEXTURE0.
DESCRIPTION¶
glActiveTexture selects which texture unit subsequent texture state calls
will affect. The number of texture units an implementation supports is
implementation dependent, but must be at least 80.
ERRORS¶
GL_INVALID_ENUM is generated if
texture is not one of
GL_TEXTURE i, where
i ranges from 0 to (
GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS - 1).
ASSOCIATED GETS¶
glGet() with argument
GL_ACTIVE_TEXTURE, or
GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS.
