GLACTIVETEXTURE(3G)						    OpenGL 3.3						       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 48.  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 48.

ERRORS

       GL_INVALID_ENUM is generated if texture is not one of GL_TEXTUREi, 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.

NAME

       glIsTexture - determine if a name corresponds to a texture

C SPECIFICATION

       GLboolean glIsTexture( GLuint texture )

PARAMETERS

       texture	Specifies a value that may be the name of a texture.

DESCRIPTION

       glIsTexture  returns  GL_TRUE  if  texture is currently the name of a texture.  If texture is zero, or is a non-zero value that is not cur-
       rently the name of a texture, or if an error occurs, glIsTexture returns GL_FALSE.

NOTES

       glIsTexture is available only if the GL version is 1.1 or greater.

ERRORS

       GL_INVALID_OPERATION is generated if glIsTexture is executed between the execution of glBegin and the corresponding execution of glEnd.
