glHint — specify implementation-specific hints
Specifies a symbolic constant indicating the behavior to be controlled.
Specifies a symbolic constant indicating the desired behavior.
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,
mode is another symbolic constant indicating the desired
behavior. The initial value for each
mode can be one of the following:
The most efficient option should be chosen.
The most correct, or highest quality, option should be chosen.
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
along with suggested semantics,
are as follows:
Indicates the accuracy of the derivative calculation for the GL shading language fragment processing built-in functions:
Indicates the quality of filtering when generating mipmap images with glGenerateMipmap.
The interpretation of hints depends on the implementation.
Some implementations ignore
GL_INVALID_ENUM is generated if either
mode is not
an accepted value.
