Alfred Shitcock  Why is this lame crap on the front page? Anyone who knows how to use stencil buffers can do this easily. If you can render a mirror, you can make a portal.

dancingshadow      That is fucking rad !! Is this guy using stencil buffers or something??! Brilliant !
|
Alfred Shitcock Apparently I have the power to decide how videos are rated by being the first to rate them. Yay!
|
futurebot Can someone explain to me what the hell is going on here?
|
zatojones Stencil buffers is what's goin' on, Jack!
|
|
Ursa_minor Hey, i heard there were some stencil buffers in here, are there any left?
|
Westward      Oh stencil buffers, your lips are like velvet.
|
Xiphias      stencil buffers are amazing!
Also: the physics of moving through portals is built into Direct3D's stencil buffers. Strange but true!
|
Alfred Shitcock The physics of moving through portals is as simple as transforming the player's movement vector from the space of one plane, into the space of the other. I would have expected a robotologist to know this.
|
Xiphias yes and if you can summarize something in a sentence that means you understand it completely and it's very easy to do
|
Alfred Shitcock It IS easy to do. Any freshman college computer science student could do it. And they did. Long before Portal came out. Just because you don't know how to do it doesn't mean it's not easy.

jihadbaby      Hey, Shitcock, will you buffer my stencil?
|
glasseye      Oooh stencil buffers. So hot.
|
yourmother    needs more stencil buffers.
|
Aelric      screw the video, the comments are where the entertainment is.
|
Feyd   This video is not very good.
|
|
Aubrey McFate How can that cop get away with stencil buffering? There ought to be a law!
|
Fingasmcgee   Now your failing with portals
|
NineEleven    I would make a comment about portals (and get IPbanned again) except...whoops 8(
|
baleen     
these pencil stuffers are really creepy
|
Keefu      stencil buffers
|
A Jumping Spider! god damn it you guys
|
ABoyNamedCheese     bencil stuffers, the lot of you
|
Olaf the Unspeakable      I could go for a buffed stencil right about now.
|
fluffy      I think Portal actually uses render-to-texture, which are a much easier way to do these things anyway (and makes it a lot easier to have portals-within-portals if you're okay with each additional layer being a frame behind the last one).
|
Cinnamon Imperialist  Memes, huh?
|
FABIO2   This video would have been sorta kinda neat in maybe 1999.
Alfred could post dog fucking videos where the dogs are dressed as Orange Box characters and you all would love it.
