I think one of the biggest features of his new engine are the vertex/pixel shaders. I don't know too much about those, but I doubt it's "just a few lines of code". If you can pull off a "Doom 3" engine in a few weeks though, post a demo, I'd love to see it

Labas2X, what is the URL of your Homepage?????
Back your words.

There are often people saying that it''s easy to build something, but when they back theyre words then you get to see crap and unoptimized stuff.

I recall a guy who had made an own interpretation of Quake Rally, he bragged about his version, that he had coded it in a week and that it was the best. When you played it you could see why it took only a week.

If you really are that fast and good then i''d like to see it, it would be a nice addition to the community.

Might be what I''ve written sounds a bit arrogant, but I didn''t want to show what a damn good programmer I am. I just wanted to say that if an average programmer like me makes an engine in some weeks, a real professional could be even faster. Hope that''s clear now.

@Promiscuous Robot: I didn''t say I''ve build a quake3 engine in
one week; it took me a month (but I only worked sometimes at the engine) and of course the engine isn''t complete. But I was completely new to C++, BSP-trees and curved surfaces, so I think that a more experienced programmer could be much faster.

If you have to invent all the algorithms, it will of course take more time, that''s right. But someone who writes an engine today doesn''t have to do much research. There are so many good tutorials and techniques (Ocllusion Culling, BSP, Octree, ...) that you can use.

@twigllet: The GeForce-cards support perxpixel-shading and all the other techniques by hardware; you just have to activate them.

@Phantom Lord: I don''t have a homepage; and I''m really not very good. But when I said that my shadows and light-effects are all
working in realtime, I didn''t lie. I will try to post a screenshot of the "doom3"-engine. Getting the shadows work correctly needed some research (yes, research, because there aren''t many tutorials) but if someone is interested in how I''m doing it I will try to help.

Thanks for all your comments

Ok, here is a screenshot:

You can see the shadows; they are all realtime and the lights are moving. It doesn't look too impressive, but it is just to test the shadows/lights.

The screenshot looks really cool, but how about "soft" realtime shadows, like in doom3 (not truly softshadows, but with kind''a blured edges)


newbie2001

Yes, the screen shot looks good. With powerfull hardware and OpenGL is things getting _much_ easier than before. It will still take some skill and time to do something great. Cutting edge stuff like doom3 is something different that is of course _extremly_ hard and time consuming.

My guess is that a group of decent programmers could do something great in something like a year.
