Okay i have done a search for this and come up blank.
It probably has been mentioned before, but i am not sure (I have perused since this forum went up but cba to register then, too many flames, but i did read 'lots').
So.........
When i watched the the E3vid and the lovely Bink of Dr.Kleiners lab the thing that really struck me as being a 'nice touch' was the Magnifying lens on the desk. At first i thought 'wow is that really magnifying', i sat amazed. Then i looked at it a little bit harder. Now i am not entirely sure, but this just looks like it's just a displaced image of whatever is behind it, at the same scale, not straight through like glass but an image slightly off-centre from the image behind giving the impression that it is magnifying.
I would assume that if you involved real optics then it would mean a large CPU overhead to calculate the refractions, hence the need to use visual trickery to avoid the CPU overhead. This has been demonstrated already in the HDR demo, not the HL2 one, but the DirectX9 spinning marbles/skull/rope thingy that was posted here before.
If you take a close look at that demo you will note that when objects (solid spinning marbles) pass behind the middle object when its material is set to a refracting material (glass, ruby, etc...) you will note that the object passing behind the refracting object is not rendered. Although light does appear to pass through the object, i doubt that it is actually being refracted but instead reflected from its surface attribute using light values that hit the back side of the object.
Two different interpretations of refraction, with differing results.
So if i assume that 'true optics' is not coded into HL2, what would be the possibility of their being a 'Glass Brick' partition wall somewhere in the game, with enemy behind that you can see moving (hopefully somehow distorted). And [fingerscrossed] will these optical objects be breakable [/fingerscrossed].
The stained glass window of Gordon in the tech demo sort of gives the impression of the glass brick, albeit a very large and colourfull one.
