1991-2006 Silicon Graphics, Inc. glHint 3G glHint specify implementation-specific hints void glHint GLenum target GLenum mode target Specifies a symbolic constant indicating the behavior to be controlled. GL_GENERATE_MIPMAP_HINT is accepted. mode Specifies a symbolic constant indicating the desired behavior. GL_FASTEST, GL_NICEST, and GL_DONT_CARE are accepted. Certain aspects of GL behavior, when there is room for interpretation, can be controlled with hints. A hint is specified with two arguments. target is a symbolic constant indicating the behavior to be controlled, and mode is another symbolic constant indicating the desired behavior. The initial value for each target is GL_DONT_CARE. mode can be one of the following: GL_FASTEST The most efficient option should be chosen. GL_NICEST The most correct, or highest quality, option should be chosen. GL_DONT_CARE No preference. Though the implementation aspects that can be hinted are well defined, the interpretation of the hints depends on the implementation. The hint aspects that can be specified with target, along with suggested semantics, are as follows: GL_GENERATE_MIPMAP_HINT Indicates the quality of filtering when generating mipmap images with glGenerateMipmap. The interpretation of hints depends on the implementation. Some implementations ignore glHint settings. GL_INVALID_ENUM is generated if either target or mode is not an accepted value. glGenerateMipmap Copyright 1991-2006 Silicon Graphics, Inc.
