I Played FarCry with Pixel Shader 3.0

ok jarred, go pick up a rock, wet it and brin git outside. it WILL NOT HAVE ANY VISIBLE SPECULAR PROPERTIES

Ok... I will take you up on that offer
AHHH!!! Too bright!!! Luckily I brought my non SM3.0 ATI hat.. hopefully it will reflect all the light:


For our experiment, we will take an everyday beach rock, and submerge it in water. We shall see how, and if it reflects light. Here is the beach rock, yes, it is on my mailbox:


Lets dunk it in water! Its kinda dark outside, so lets take it in the bathroom light: (Bonus game, spot the hidden A64 logo!!)


I see a small sparkle there!! Luckiley my ATI shirt had no reflections, as to not distract me from the rock. Lets take the rock back outside:


No shine?!?!??! I think we need to conduct this experiment when it is more light outside.. until next time... Unfortunately my experiment was non-conclusive.

... lol ill give u points for ur humor, but seriously that is not the type of rock i was referring to. if olnly we were so lucky to have beaches littered with mechanicly smoothed and polished kitten rocks.

Oh well, I became bored... Nothing like Googling around for high school physics that I'm foggy on to say the least. Anyway, specular reflection can occur with most any surface, given that it is either naturally "smooth enough" or if something (water) fills in the otherwise rough surface. Heck, paper exhibits some specular properties, as anyone who has tried to read with a high intensity lamp can attest. Below is a good link for more information and this quote which goes along with what I just said.

There are several interesting applications of this distinction between specular and diffuse reflection. One application pertains to the relative difficulty of night driving on a dry asphalt roadway compared to a wet asphalt roadway. Most drivers are aware of the fact that driving at night on a wet roadway results in an annoying glare from oncoming headlights. The glare is the result of the specular reflection of the beam of light from an oncoming car. Normally a roadway would cause diffuse reflection due to its rough surface. But if the surface is rough, water can fill in the crevices and smooth out the surface. Rays of light from the beam of an oncoming car hit this smooth surface, undergo specular reflection and remain concentrated in a beam.

Back to that FarCry beach. The rocks could be wet...I mean it is a beach, right? Even if the rocks are not wet...why be so hellbent about the likelihood of that being a hemitite covered beach or not? What's the big deal? The last time I checked there are countless liberties with physics, visual properties, physiology, etc, etc, etc that game developers take...they are games afterall.

allright. now you got the man outside wetting rocks down, and I applaud his effort. - the world is full of rocks, some shine when wet, some dont, apparently the beaches of farcry shine! weeeeeeeeee!!

alright dude, you forced me to do this!

just wait one minute!

[Jarred]

ok, so since it's Dark here, I opted for using normal kitchen light, heck why not? the sun is WAY brighter than anything I have in my house...

so, as you can SEE (the red arrow) there is in fact specular properties to this wet rock.

and if you still don't think so, then...maybe your thinking of something else?

btw Thanx for tying Jakup,

Oh nooooose! Jarred took a picture of some massive terd!

Ewwwww....you gross man.

[Jarred]

WOW ! Jakup your a walking ATI ad!

[ClosetFanBoy]

nope. jarred you cheated, you dunked yours in the oiled down forceware 68.00 drivers.

[Jarred]

and since jakup posted his mug I'll post mine...

yeah thats right I don't look like

LOL, na I think it was only requesting true trilinear specular when color maps were used...
