When I double clicked on BSP Tree thingy and it just turned my desktop to 1024x768 res (I was at 800x600). Oh well, I didnt think it would work on my diamond stealth s540 card anyway. Thats pretty cool you can make something like that, I can only do qbasic https://www.sharkyforums.com/images/.../2005/06/6.gif.

What kind of BSP tree are you using? Solid? Leafy? Are the lighmaps calculated realtime?Quote:

Just some questions since I'm writing a 3D engine with a couple of friends and we have a editor going and a simple renderer. Hopefully by the end of the month we will be able to have a deathmatch game going https://www.sharkyforums.com/images/.../2005/06/5.gif
Just out of curiosity, what kind of languages does someone use to create Linux games?

On my Celeron 1GHz running a TNT2-A, I get 28-42 fps. Looks pretty cool, but you need to work on the lighting. Screenshots work fine. I get a few glitches though, and sometimes I simply get "stuck" (weird graphics shaking on the screen) and have to press "Esc" or reboot...

Well, it doesn't contain any information about solidity. It's simply a split of the surfaces with the splitting surface in each node in the tree.Quote:

The lightmaps are static and are generated at startup, I'm investigating a little on how to implement dynamic lighting and have a few ideas. It'll probably need two extra passes on the surfaces involved.
I'm no Linux guy but I guess C/C++ is most mostly. Probably OpenGL (or Mesa) for the graphics.Quote:

The reason the lighting looks wrong on your system is because the TNT2 doesn't support DOT3 bumpmapping. My engine doesn't check if it does so the drivers will probably just modulate the bumpmaps with the base texture giving a little strange look. Bumpmaps tends to be mostly purple. If you look on the screenshot at the same page as you downloaded it from you'll se how it's intended to look. It's a little small pic but it'll give you an idea.Quote:

The textures don't look anything on my TNT2 than they look on the screenshot http://dev.www.sharkyforums.forums.relay.cool/Quote:

Nah, I don't game a lot, and even when I do, it's for adventures and RPGs which don't *really* need a lot of graphics power...Quote:

Just tried it on my pc at home. I got between 290 and 600 fps according to the counter, the textures were all messed up, it changed my screen resolution from 1280 to 1024, my system became very slow and I had to use taskmanager to get back to windows.
Here are my specs:
PIII 733
Abit SE6
256MB CAS3
Matrox G400 32MB DH
Creative 1024 Live
Windows 2000 SP1
latest drivers for all
It's probably not your program that's messing up, but something in my system.
It's probably a mix of my application not checking for support for bumpmapping (I've used DOT3 bumpmapping not the EMBM bumpmapping used by G400) and the drivers for G400. I owned a G400 before my Radeon and were never really satisfied with the OpenGL driver. It took them a year to get stencil buffering in there ...Quote:

Sorry I meant were you calcuating the static lighmaps at startup https://www.sharkyforums.com/images/.../2005/06/5.gif How are you doing collision detection without using Solid BSPs? They are very easy to implement and very fast when it comes to collision detection.Quote:

Yo I was wondering....how long would it take to create a really great Engine (Like Quake 3 and Unreal) by yourself?
BTW Yours is awesome how long did it take you to make?

Well, yes, they are calculated at startup. I don't know the actual definition of a solid bsptree but I have not implemented my bsp tree the same way as another bsptree example I saw which was said to be solid ...Quote:

Anyway, you can do collision detection by checking with two point if the line between them intersects a polygon. You start at the root node and check on which side of the polygon the two points are. If they are on the same side (which is very very likely) you can cull all the polygons on the other subtree thus reducing the amount of polygons to check to half each step. If they are on different sides you need to check both subtrees and the polygon itself.
This way you can not just extract solidity information, but you can also get the line of sight or intersection point. This also makes doublesided polygons possible.
