Version
Last Modifed Date: July 18, 2017
Dependencies
This extension is written against the OpenGL ES 2.0 specification.
OpenGL ES 2.0 is required.
Overview
This extension defines a way to request high precision texture filtering
using a new value to Hint.
When this extension is enabled, TEXTURE_FILTERING_HINT_CHROMIUM can be used
by the implementation as a means to distinguish between a performance
focused implementation, using FASTEST, or a precision focused
implementation, using NICEST.
Like other hints, either option is spec compliant and the behavior of
DONT_CARE is implementation specific.
New Tokens
Accepted by the <pname> parameter of GetIntegerv, GetFloatv and GetBooleanv
and by the <target> parameter of Hint:
TEXTURE_FILTERING_HINT_CHROMIUM 0x8AF0
New Procedures and Functions
None.
Errors
None.
New State
None.
Issues
1) When does the hint take effect?
At the time of the next draw call, and all subsequent draw calls.
2) Does the first draw call after the filtering hint is changed use the
updated filtering method?
Yes
3) Can I switch it back and forth between every draw call, multiple times
during a single frame?
Yes
4) Do program objects which were created before the filtering hint was
changed and which contain sampling instructions use the filtering method
from when they were created, or the method at the time of draw call?
At the time of draw call.
