For large scale factors, hinting GL_NICEST produces the 355bd8deadSopenharmony_ci most accurate results. The hint only applies to Octane2 VPro 365bd8deadSopenharmony_ci graphics systems, to work around a hardware issue. 375bd8deadSopenharmony_ci 385bd8deadSopenharmony_ciNew Procedures and Functions 395bd8deadSopenharmony_ci 405bd8deadSopenharmony_ci None 415bd8deadSopenharmony_ci 425bd8deadSopenharmony_ciNew Tokens 435bd8deadSopenharmony_ci 445bd8deadSopenharmony_ci Accepted by the <target> parameter of glHint and by the <pname> 455bd8deadSopenharmony_ci parameter of GetBooleanv, GetIntegerv, GetFloatv, and GetDoublev: 465bd8deadSopenharmony_ci 475bd8deadSopenharmony_ci SCALEBIAS_HINT_SGIX 0x8322 485bd8deadSopenharmony_ci 495bd8deadSopenharmony_ciAdditions to Chapter 2 of the 1.1 Specification (OpenGL Operation) 505bd8deadSopenharmony_ci 515bd8deadSopenharmony_ci None 525bd8deadSopenharmony_ci 535bd8deadSopenharmony_ciAdditions to Chapter 3 of the 1.1 Specification (Rasterization) 545bd8deadSopenharmony_ci 555bd8deadSopenharmony_ci None 565bd8deadSopenharmony_ci 575bd8deadSopenharmony_ciAdditions to Chapter 4 of the 1.1 Specification (Fragments and the 585bd8deadSopenharmony_ciFrame Buffer) 595bd8deadSopenharmony_ci 605bd8deadSopenharmony_ci None 615bd8deadSopenharmony_ci 625bd8deadSopenharmony_ciAdditions to Chapter 5 of the 1.1 Specification (Special Functions) 635bd8deadSopenharmony_ci 645bd8deadSopenharmony_ci Add to section 5.6 ("Hints"): 655bd8deadSopenharmony_ci 665bd8deadSopenharmony_ci If the <target> argument of Hint is specified as SCALEBIAS_HINT, 675bd8deadSopenharmony_ci then the <hint> argument indicates the desired precision of 685bd8deadSopenharmony_ci geometric transformations around the near clip plane (XXX - is this 695bd8deadSopenharmony_ci really what's going on?).
