Postfx - using, tutorials, galery ?
« on: September 12, 2011, 10:48:14 pm »
Hello!

I have a some questions. I would like to use postfx, but not quite know how.

What exactly i should to read? I will need to learn all OpenGL or something tutorials will be enough to write own effects?

Mayby is somewhere galery/colletion of ready postfx effects?

If I recall correctly, the PostFX use a slightly different shader-syntax than regular fragment/pixel-shaders. You have tutorials on the official site: http://www.sfml-dev.org/tutorials/1.6/graphics-postfx.php

If you plan on using SFML2 in your project, wich i highly recommend, you should know postfx is no longer used, and is replaced by fragment/pixel-shaders as well as (probably) vertexshaders.
