Anyone have a good list of tutorials on doing Non photo realistic rendering with GLSL ? I have seen books on GLSL, and books on NPR, but very few books/tutorials on doing NPR with GLSL. (I want to do it with GLSL as I want real time).
Thanks!

I need to debug a GLSL program but I don't know how to output intermediate result.
Is it possible to make some debug traces (like with printf) with GLSL ?

Hi All,
I am trying to get update the eye position in my shader from my appliaction but I keep getting error 1281 when I attempt this. I have no problems after the initialization just when i subsequently try to update the values. Here is my code:
void GraphicsObject::SendShadersDDS(char vertFile…

I am currently writing the positions of my geometry to the RGB channels of gl_FragColor and I would like to write 1.0 to the alpha channel if the fragment is part of geometry, and 0.0 if its empty.
Is there a simple way to tell if a fragment is geometry or not? Maybe through gl_FragCoord.z?
thanks

I need a datastructure of the same size as the normal depth buffer and I need to be able to read from and write to it in a shader. Is this possible, and what does this datastructure look like?

To support videocards in laptops I have to rewrite my GLSL 330 shaders to GLSL 130. I'm trying to do this but somehow I don't get vertex attributes to work properly.
My 330 shaders look like…

First of, let me apologize for this getting a bit technical. Several weeks ago, I found that while using NPR's media player (e.g. click on 'Listen to the Show' - this is what I've been using as a test) the stream would suddenly halt after a minute or three. I could not get the stream to restart…

While it seems like every summer people complain about the heat, this summer there’s a basis to their grievance. In the past month there have been 4,230 daily high-temperature records set across the continental United States. Over at NPR they’ve rounded up some environmental data that…

I'm trying to assess the difficulty of creating a rendering style that is more like the game Okami and the Quake mods (as shown on this page...search for 'okami','quake npr'). Here's a better page describing the Quake rendering mod.
Can a game engine such as Unity be used and programmed to achieve…
