What's meaning of 'the CENTER of 13th texel'? Isn't a texel the minimal unit for sampling?
- The sentence in question is attempting to explain where a particular non-normalized texture coordinate goes to in texel space. Because rectangle textures can undergo filtering, they are not discrete spaces. So if the coordinate means "the center of the 13th texel", that can give a different value from "the left edge of the 13th texel" depending on the filtering mode. The latter will filter against the 12th texel; the former will not. Alfonse (talk) 18:05, 26 November 2019 (UTC)
