u2 Bleank / The Blog

On twitter I saw this tweet from John Carmack

And it’s remember me an entry on the blog of John Hable about Gamma Correction.

I’m currently developing User interface rendering with DirectX and shaders then I must take car of correct Anti aliasing computation for typos or little vector shapes.

But I never reach the contrast of the font system rendering. I know there’s some hinting and clear type on it but I was not satisfied by my results.

So I decide to read carefully this excellent article about Gamma Correction and made some test.

The result was what I excepted at the beginning. The font rendering is now contrasted and even really little characters are now lisible and clean.

Here come the result :

Before whitout Anti-aliasing Gamma Correction

After with Gamma Correction

Thanks to the two John I will take care of the correct Gamma Correction everywhere in my framework for event better rendering ;)
