GLACTIVETEXTURE(3G) [FIXME: manual] GLACTIVETEXTURE(3G)

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 zero to the value of GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS minus one. 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_TEXTUREi, where i ranges from zero to the value of GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS minus one.

ASSOCIATED GETS

glGet() with argument GL_ACTIVE_TEXTURE, or GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS.
