I've been working on a level editor for about a week.

Right now I only have sectors, extrusion and sector subdivision implemented, but later on it's going to support positive-space volumes, patches and path lofting.

Is there a specific game it's targeting?

What, like this?...

e: Design-wise, that's about all I control on this project. The colors (a zillion shades of blue and grey, fonts, sizing, etc are all Design By Committee. That looks... a bit odd, but it's been a helluva day and if I can make one person happy, so be it.

Stuff looks like it goes a few pixels farther on the right than on the left. :downs:

Fix this and somehow get the logo aligned with controls AND centered, and I'm sure that for that one brief second after it happens, the world will be a truer and more beautiful place.

edit: oh jesus, it looks like it already happened.

q3map2's approach is conceptually a decent idea: It takes polygons and chops them up until the light gradient is low enough, then spawns area lights from them. The approach I'm using is just faster because doing a scene render and running a big SIMD multiply/accumulate over it faster than casting a light by several orders of magnitude.

Of course, q3map2 is further impaired by its light casting algorithm being slow AND scaling very poorly.

What Q3 code base are you using as a base? IOQuake, CPMA, Vanilla?

How much of it is left? I remember Carmack somewhere saying about how he wanted to modernize the renderer a bit by adding support for VBO's, etc for Quake Live, but he didn't in the end because of time (i think was the reason).

Babbies first software renderer, uses GDI, a DIB section. It also has a really basic quake style console, and can load, draw, and scale bitmaps, which it uses for text drawing.

It can't fill triangles yet though or load models, so I've just been copy pasting the model verticies / indicies.

I tried making munching sqaures for it but it's brutally slow because I suck

code:

for(int y = 0; y < height; y++)
{
	for(int x = 0; x < width; x++)
	{
		int t = frameCount;	

		if((x ^ y) < t)
			set(x, y, color(x ^ 255, y ^ 255, t));
		else
			set(x, y, #000000);		
	}
}

I hosed my windows install and didn't back much of anything up so I ended up starting to rewrite my lovely software renderer for the last few days.

Design is a bit smarter and a bunch of stuff is vectorized now like surface manipulation, the math stuff like matrix and vectors, and all the transformation stuff. It also actually has a proper timer so I can set / get the FPS... though it seems too high to get anything meaningful if I leave it uncapped in a simple scene at a low resolution.

It hasn't regained the ability to draw lines yet but if you look carefully you can see the vertex pixels that make up my cube :downs:

It's actually less to look at than the first post I made on this because I had wireframe triangles working then... but this is totally more impressive in the underlying implementation of everything even if you can't see it. :v:

I felt inspired and got wireframe back in :c00l:

Next up is actual model loading so I can get away from this cube already and maybe stress it a little.

edit:
Testing out my new SSE transformation stuff. With no drawing, it plows through 1,048,576 verticies at about 12 fps. :v:

It's about 90%~ faster than the x86 version. Kind of ridiculous scaling, really surprised me. About 327,680 clocks in around 38 fps.

I still have a lot of room for improvement. Maybe I'll look into threading stuff eventually, as well.

Maybe I'm just stupid, but how in the hell are you doing that in command prompt?

I just give GetDC() the console window handle.
