25 This extension is written against the OpenGL ES 2.0 specification.
27 OpenGL ES 2.0 is required.
31 This extension defines a way to request high precision texture filtering
32 using a new value to Hint.
34 When this extension is enabled, TEXTURE_FILTERING_HINT_CHROMIUM can be used
35 by the implementation as a means to distinguish between a performance
36 focused implementation, using FASTEST, or a precision focused
37 implementation, using NICEST.
39 Like other hints, either option is spec compliant and the behavior of
40 DONT_CARE is implementation specific.
44 Accepted by the <pname> parameter of GetIntegerv, GetFloatv and GetBooleanv
45 and by the <target> parameter of Hint:
47 TEXTURE_FILTERING_HINT_CHROMIUM 0x8AF0
49 New Procedures and Functions
63 1) When does the hint take effect?
65 At the time of the next draw call, and all subsequent draw calls.
67 2) Does the first draw call after the filtering hint is changed use the
68 updated filtering method?
72 3) Can I switch it back and forth between every draw call, multiple times
73 during a single frame?
77 4) Do program objects which were created before the filtering hint was
78 changed and which contain sampling instructions use the filtering method
79 from when they were created, or the method at the time of draw call?
81 At the time of draw call.
