Hi all, I am trying to find a decent 3d World ( not modeler ) software that can export my 3D world ( polygons ) in a simple text file format that can be used by my OpenGL engine. I downloaded and am trying Morfit 3D Worldbuilder, but the format is going to take a lot of conversion effort. I guess before I move forward with developing worlds/levels for a game, I would pose the question to a forum and get some much needed advice. I have looked at DesignCAD, seems reasonably priced, but there is no info ( or indication ) that it will export into an OpenGL format. I am also considering another product called WorldBuilder ( by Digital Element ), it''s pricy, but it clearly states in the info that it supports OpenGL formatting. Has anyone used this software before? tia, adym

I have used World Builder to make Half-life maps, It was pretty easy to work from my side and I managed to pull off some pretty nice levels

As long as you stick to inclosed areas you cant really go wrong

It does lightmapping and stuff like that too

Thorin_nz,

Cool! I don''t suppose you have some lines from a file that this thing produces. I''d like to make sure the output from WorldBuilder is ''truly'' OpenGL. Some software states that it OpenGL ''compliant''...So you buy it only to find out you have to run thru some other software to get true OpenGL coordinates...

tia,

adym

WorldCraft is also nice (another HL-editor). Just search for cs editing and you should have no problem finding it. It can export the worlds as .map files which are quite simple to understand.

Example for a simple cube in worldcraft:


{
"classname" "worldspawn"
"wad" "\spel\counter-strike\valve\liquids.wad;\spel\counter-strike\valve\halflife.wad"
{
( -512 512 512 ) ( 512 512 512 ) ( 512 -512 512 ) 64CRATE0 0 0 0 1.000000 1.000000
( -512 -512 -512 ) ( 512 -512 -512 ) ( 512 512 -512 ) 64CRATE0 0 0 0 1.000000 1.000000
( -512 512 512 ) ( -512 -512 512 ) ( -512 -512 -512 ) 64CRATE0 0 0 0 1.000000 1.000000
( 512 512 -512 ) ( 512 -512 -512 ) ( 512 -512 512 ) 64CRATE0 0 0 0 1.000000 1.000000
( 512 512 512 ) ( -512 512 512 ) ( -512 512 -512 ) 64CRATE0 0 0 0 1.000000 1.000000
( 512 -512 -512 ) ( -512 -512 -512 ) ( -512 -512 512 ) 64CRATE0 0 0 0 1.000000 1.000000
}
}


(cut down the wad files list)

What does that mean, exactly? You know there''s no such thing as an "OpenGL file format", right?

Jolle,

Thx for the tip, I''ll check that out as well.

Anonymous,

Correct! There is no such format as OpenGL. But, what I''m after is a simple text format (ascii). Bottom line, I just want the raw vertices as floating point values (x, y, z) ...

5.00 5.00 5.00
5.00 5.00 -5.00

etc... I can fill in other stuff (textures, alpha, etc...) later.

The Morfit WorldBuilder does provide raw vertices, but there is a considerable amount of texture, object, etc... data in the file as well, meaning I would have to put time/tools in to strip out the stuff. But, if I can buy something, or better yet find something for free, then I can avoid having to write tools to modify the Morfit files...

Just an update...I''m also checking out AC3D and Blender, but these look more like 3D modelers, not 3D worlds.

tia,

adym

Valve released a mod of WorldEditor called Hammer, I think this was freeware aimed at developers for the hl engine as it would let more people make maps and therefore make thier game better...

Something like that anyway, It is pretty much exactly the same as worldcraft...

Also the Unreal editors are pretty easy to use once you get used to how they work, but I havent looked at the file structure that they produce, it may be a bit bloated for what you looking for as it contains bot waypoints and crap like that

later
