How does Q3 billboard(flare) renders? I know how to turn it to a viewer, but I don't know WHERE in .BSP stored size of billboard, blending, and is it a GL_QUADS or GL_TRI...? It's should be fine to see simple code or program. (I can't find in qfusion place where this rendres, but I understood that flare is internal shader. But... how to?) P.S. Sorry of my bad engish:)

It's a regular triangle, it's the shader that makes the engine treat it as a billboard.

just a side note, i dont believe a single triangle is the way to go, do a quad... theres no reason to use a triangle over a quad that i can think of
just my 2 cents

Q3 md3's only store data as Triangle format, so its not even
an option.

to use any surface as a billboard, you need a shader parser setup.

i will be writing a set of tutorials on the Quake3 BSP format
on how to write a complete loading engine for them (i think
its a great test-bed fileformat because its easy to render
and very flexible).

to silvermace:
It's great that my engine FPS is higher than Q3. Really!
On some computers. On some another it loses a little.
But w/o billboard!
My engine is not a thrash as at gametutorials.com, for example.
(But it's gooad to learn how q3 BSP bulit, and I did it).
There no memory manager, picmip, mipmap on/off, config,
bezier patches (I support any degree, not only 2 as in q3),
node frustum cull (really fast). My engine have ability:
OS independency, logging (on/off), and other.

I can send a demo.
