@casseveritt @nothings @g_truc I don't know that I agree with that. Isn't it a transform _and_ a set of clipping planes?

@casseveritt@nothings@g_truc I mean, as compared to "just a transform"... the viewport "takes the planes with it", so to speak.1 reply 0 retweets 0 likes -

@cmuratori@casseveritt@g_truc The clipping planes are hardwired. The viewport is one of several transforms that get you to clip space.1 reply 0 retweets 0 likes -

@nothings@casseveritt@g_truc But it's not, right. I mean, yes, it is a "transform" in the broad sense of the word...1 reply 0 retweets 0 likes -

@nothings@casseveritt@g_truc But other transforms cannot affect where things are _after_ clipping. Does that make sense?1 reply 0 retweets 0 likes -

@nothings@casseveritt@g_truc So I feel like it is disingenuous to say it is "just a transform", when it has a property others don't.1 reply 0 retweets 0 likes -

@cmuratori@casseveritt@g_truc I guess it's different in that happens after clipping, so you can think of it as defining space of clipping.2 replies 0 retweets 0 likes -

@cmuratori@casseveritt@g_truc But it's better to *not* think of it that way so you can understand e.g. why it doesn't clip glClear.2 replies 0 retweets 0 likes -

@nothings@cmuratori@casseveritt@g_truc Viewport is just another transform, and applies to primitives. Clears are not primitives.1 reply 0 retweets 0 likes
@basisspace @nothings @casseveritt @g_truc Except it's _not_ just another transform, because it does things other transforms can't.

@basisspace@nothings@casseveritt@g_truc Other transforms can't move shit _post clip_. Make sense?2 replies 0 retweets 1 like -
Replying to @cmuratori
@cmuratori@basisspace@casseveritt@g_truc The point is it's "just" a post-clip transform. See e.g. #10 at http://www.opengl.org/archives/resources/features/KilgardTechniques/oglpitfall/ …1 reply 0 retweets 0 likes - Show replies
