The number of texture units is implementation-dependent, but must be at least 32. 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. 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 32. 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. glGet with argument GL_ACTIVE_TEXTURE, or GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS. glActiveTexture glGenTextures, glBindTexture, glCompressedTexImage2D, glCompressedTexImage3D, glCompressedTexSubImage2D, glCompressedTexSubImage3D, glCopyTexImage2D, glCopyTexSubImage2D, glCopyTexSubImage3D, glDeleteTextures glIsTexture, glTexImage2D, glTexImage3D, glTexSubImage2D, glTexSubImage3D, glTexParameter, Copyright 1991-2006 Silicon Graphics, Inc.
