Why can 3d objects only be made up of straight lines in 3d graphics? In 2d graphics, you can do what you want (well i think you can).

What do you mean by saying "you can do what you want"?

2D graphics, by this I hope you mean Sprites?
They can be what you want because they are designed to always face the player. They are not solid.
3D objects are solid.

I was just talking in the general sense, like in terms of what's applicable to computer games, when I was mentioning 2d & 3d graphics. When I said you can do what you want in 2d graphics, I just meant that you could use bent lines as well as straight ones.

not to mind you but everything in this universie is build out of blocks. even the smallest atom and if you want such a thing aplied in a computer game you would nned such a fast pc wich doesnt excist yet. and the face you would need over 20 million molecual's isnt really anice thing to thiunk about

:

it isnt that hard.....i think

Take a close look at 2D graphics. They're not bent lines. They're pixels. The higher the resolution, the smoother it will look. The more polygons you use, the smoother the shape will look.

Besides, it's possible to base a 3D shape on a curve. I believe it's called NURBS. Do a search on Google to find out what they are. You may find it quite interesting...

What I really meant was why can't any 3d game support completely rounded spheres?

Some can. Search for NURBS and what they are. They're not based on faces but on a mathematical function. Much easier to render (for the computer) and looks very smooth.

But I doubt there are much engines that use it right now. But it is possible. Several modeling programs use it.

HL dosent support it, but It's definately possible, it's
in the OpenGL library. If you code any OpenGL, you'll find you can draw spheres, cones, and cylenders very easily.

did they not support it because it would screw people with slow computers?

it wasnt avalible at that time i think
