Preserved Topic: F@$% what about DOOM (Page 1 of 1)

Ok i bet u all know "DOOM" anyway was the first game 3D...some peopel say it is , but for me its flat and pixelated so I wouldnt say it really is 3D.... ahh shit of course its not 3D, damn everything is flat..but then how did they gave a posibility to move in 3D...well shit explain i am confused!

It's not total 3d.
That is, it used sprites in a 3d environment.
The maps are 3d, but the monsters are flat.

People say Doom II was the first total 3d game.
However, I remember Descent being out before Doom II.

I consider doom the first 3d game because the environments were 3d, and there were diagnal walls in the maps too along with ramps and other such 3d things. But I think Wolfenstien deserves some credit as well. It was pretty sucsessful and I don't think Doom would have been created if it hadn't been sucsesful.

Plus Nazis are funnier to kill than aliens =)

Depends on your definition of 3D. I'd consider Starglider to be more of a 3D game than Doom, since you fly around in full freedom of movement. It's a wireframe flying game from 1986. Doom could only do perfect vertical and perfect horizontal planes; you didn't have full freedom of movement. It came out in 1993.

Actually, I remember playing Akalabeth on the Apple ][ back in 1979. It was a wireframe hallway exploration game, and definitely showed a 3D scene in realtime. It was in wireframe, with no visible creatures, and even more limited perspective than Doom (you moved in 'steps'), but it was 3D of a sort.

LOL Emps,

I remember playing it on the Amstrad 464 and 6128, the first filled 3d space adventure, (the only version that actually had filled space ships .

then came along star wars and the wire framed 3d version of the attack on the death star, damn i feel old.

Hehe, I just discovered that even X-wing came out before Doom (by 1 year), and it was full freedom of motion AND textured objects. I loved that game

Ohh....

What about that tank game? The one where you had two joysticks to maneuver and you had to look through that gaudy periscope thing. Man, I really hated the UFOs.

Battlezone, I think that one was called. One of the old vector games. I played that one a lot

The poster has demanded we remove all his contributions, less he takes legal action.
We have done so.
Now Tyberius Prime expects him to start complaining that we removed his 'free speech' since this message will replace all of his posts, past and future.
Don't follow his example - seek real life help first.

On the topic of raycasting -

The way I've always seen raycasting described makes a good argument for Doom not being a 'real' 3D game at all. A raycasting engine can be described as (and is often implemented as) a 2D raytracer. The levels are created as lines on a 2D map, and the engine casts several rays from the viewpoint in a 2D arc. If a ray hits a line, it knows to draw a wall at that point.

The extension of the lines upward into walls (and the addition of ceiling/floor) are drawing tricks done at display time. For instance, the distance to the wall determines the top and bottom points of vertical line that will be drawn for that wall at that ray-angle. Since the eye-line is locked to the horizon (you can't look up or down), the bottom or top of a wall at a given distance is always the same. The program doesn't actually keep any positions (player, monsters, walls) in 3D; everything just has a location on a 2D map. It doesn't draw 3D objects, it just draws vertical lines and figures out where to start and stop them based on the 2D distance to the wall-line.

With a display recoding, you could easily play Doom in top-down mode, with icons for the player and monsters, and lines for the walls. That might actually be fun to do; the source code for Doom is public now

*gulp*

REALLY?!?!?!?

where????


Code - CGI - links - DHTML - Javascript - Perl - programming - Magic - http://www.twistedport.com
ICQ: 67751342

Let me hazard a guess...
Google stuff.

Might be fun to sift through.

Source code for Descent has been public as well for some years.

Hey, looks like Quake II is also public: click.
