comment GLSL - Rewriting shaders from #330 to #130
@nilstatic So what have you changed and what still doesn't work. Maybe you can edit your question to include the new 1.40 shaders. If you already got 1.40, maybe you just have to change the use of your custom position varying`to gl_Position.

@Jonathan And by the way, I have already written those reminders in first questions not answered by me. But you're right in that it is a bit self-interrested here.

comment GLSL - Rewriting shaders from #330 to #130
@Jonathan Wasn't meant that way. It's not rude to not accept if the answer was not of help. Actually the OP has maybe accepted my answer too fast (sorry for that). But I often (even in my still short SO-life) I see one-time visitors ask a question and then completely forget about it (maybe they solved it 3 minutes later themselves or they mistook the site as a forum). But the reputation system is the driving force of this feedback oriented Q&A site. It wasn't meant to immediately accept my answer without thought, but as written, to be aware of the accept feature (as many newbies aren't).

Don't forget to inform yourself about the accept and up-vote features.

comment Why is programmable pipeline( GLSL ) faster than fixed pipeline?
@iamcreasy I don't have a reliable source (therefore the probably), I have to admit. But I strongly doubt, that nowaday's graphics cards (which are just a bunch of many small processors), still have dedicated hardware for computing lighting or fog computations. Instead it is more likely they just load pre-compiled programs for this into the specific shader stages (whether these come from the driver or some ROM storage, I don't know).

comment What is a reasonable OpenGL version baseline for a mid-range 3D game?
@Nicol Could provide some short information about why subroutines are a bad idea? bad design, low performance, buggy implementations? Would be interresting, as I haven't heard about that before (and not worked with them either).

comment What is the purpose of the canonical view volume?
I don't see any part where he asks what the projection matrix does. He just seems to wonder what the normalized device coordinates are for.

comment 3D Ray Casting / Picking
@Notabene It's actually the inverse of proj*model, like you did in your example (if I assume g_LightViewMatrix means g_CameraProjectionMatrix)

@Sebastien And for a Minecraft-like game, developing you own small specialized graphics engine might really pay, performance-wise, as long as you make good use of the above mentioned features and don't just draw glBegin/glEnd cubes.

comment What is a reasonable OpenGL version baseline for a mid-range 3D game?
@Sebastien When drawing many textured cubes (something Minecraft-like, eh?), feautures like instanced rendering, texture arrays (forgot to mention those) and maybe the geometry shader come quite handy, especially instanced rendering (maybe together with transform feedback for culling). So I think GL 3 would really be a reasonable choice.

comment What is a reasonable OpenGL version baseline for a mid-range 3D game?
@Nicol I actually used it for separate_shaders, subroutines and program_binary together. I didn't know subroutines are evil, as I only have 2.1 experience.
