CS: Source Graphics Mod

[|cyborg|]

I wonder why valve didn't already have features like this, but theres always the the mod community to the rescue!

Here's a bump-mapping example. It's not perfect, because true bump-mapping requires light sources in motion - but here's an example of why bump-mapping works:









These images are exactly the same, only one is rotated 180 degrees. Notice the trick it plays on your eyes - right side up, the words "bump map" appear to be recessed. Upside down, the words appear to be beveled up. The same principle of lighter vs. darker areas interacting with a lightsource basically fools the eyes into seeing depth.

Thanks asspennies! Very cool example. Not only are you named after possibly the greatest single sketch in comedy history (I assume), but you're educational and informative as well.

[asspennies]

They call me a triple threat.

Bottom line guys, is it worth it?

[asspennies]

If you have a graphics card (and processor) that can handle it, absolutely. It only adds to the game, assuming it works correctly (haven't tried it yet.)

[gumplunger]

Yeah the changes aren't that noticable all of the time, but when they are, it's definetly worth it.

Is there any chance you can make the terroists trousers heavily bump mapped on the camo just for me <3

Hah, there wouldn't be any bumping with the cammo at all if I had the oringal .psd files for the textures. But working with just the finished textures has some limitations; hence it was basicly either no bumpmaping at all for the pants or quilted cammo, and the latter came out looking better overall.

nice, but you forgot to add that the reason one of them looks recessed and the other raised is because our brains naturally assume a light source to be coming from above (eg the sun).

Sure, that's true, but I didn't feel it was neccesary to go into the anthropological reasonings behind the example for it to be reasonably explained.



But yes, bump mapping works because of an optical illusion in which our brain uses certain visual light cues to simplify processing. It's a fascinating example of organic processing at work, when you think about it. If you stare at the image long enough, you can fool your brain into seeing the reverse image. The concious mind can really do a number on the old noodle's visual cortex.

Nice little mod. Not much of an impact on resources if you have a reasonable gfx card and cpu.

AS I LAY DYING RULES MAN! (gumplunger)



Kick ass band, listen to Heaven Shall Burn, Unearth, and that stuff to.



Also I just downloaded it, trying it now, will be back to write again.

it's funny, i've noticed with asspennies example pictures, even if i turn my head upside down, combined with my sense of gravity, both seem to keep their "bumpness" they don't appear to flip inside out to me, but instead my brain keeps them still because my sense of gravity (thus sense of up and down) changes to correspond to what i'm seeing.

[asspennies]

It's easy to test yourself - take one of those pictures, load it up in irfanview, and rotate it.



And yeah, your mind will try to keep things consistant, so if you try to fool it by turning your head it will adapt. Your depth perception doesn't suddenly flip around if you stand on your head.
