Specify implementation-specific hints.
||-||Specifies a symbolic constant indicating the behavior to be controlled. |
||-||Specifies a symbolic constant indicating the desired behavior. |
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
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
target , 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 sampling quality of antialiased lines. If a larger filter function is applied, hinting |
||-||Indicates the sampling quality of antialiased polygons. Hinting |
||-||Indicates the quality and performance of the compressing texture images. Hinting |
The interpretation of hints depends on the implementation. Some implementations ignore
GL_INVALID_ENUM is generated if either
mode is not an accepted value.
