[gameprogrammer] Re: 2D vs. 3D was RE: Re: PC game Outsourcing

Hey Jason,

2d is in theory faster than 3d since the computer works in 2d (well RAM is
1d really but yeah....)

however...since modern video cards are setup w/ all sorts of 3d hardware
accelerations, your fastest way to draw 2d is actualy to go through the 3d
interface to gain all the hardware acceleration (:

this is actualy a good thing too doing 2d drawing using a 3d interface.  It
handles alot of things for you such as clipping, rotating, skewing, zooming
in/out, etc.

Also if youve done any 2d stuff you know you have "alpha" abilities where
you can make things transparent at different levels.  In something like
OpenGL, transparency is only one of many many things you can do with the
alpha channel.  You can do lighting with multiplicative or additive blending
for instance.

GL also has things like fog built in which you could even use for your 2d
application.

and, like you said you can use models to draw to the screen instead of
pre-rendering them which is cool cause you can animate/distort the models at
run time to acheive some cool things you cant do with pre-rendered sprites.
