What are you working on?

Thanks. Projectiles.. the current effects are placeholders, and for some the trail is just way too long. I'll eventually make them from models or sprites. Maybe some projectiles would appear more beam like and follow player's movements/v_angle. Maybe it would fit for the E-Blade and Laser Rifle.

Wrote a quick and dirty script to automatically and regularly fetch Quake source code repositories: https://github.com/SpiritQuaddicted/quake-code-archives

Tell me about more public repositories or even better, add them to the lists for me.

Slap that room together, and out the door with it.


Nested transparent AND alphatest (holes) textures in Q2 software renderer.

I have added soft shadow mapping to the Doom 3 BFG edition recently.

You can get it from https://github.com/RobertBeckebans/RBDOOM-3-BFG/releases

old hard stencil shadows



new soft shadow mapping

[scar3crow]

Looking nice Tr3B. I'd like to see that in action for the segment where you are following the glowing specimen chamber through the corridors.

[qbism]

Looks like soft shadows also have longer 'range'? That pic adds shadows from the grates (very nice!) and a dark shadow on lower leg maybe from the clipboard.
Apparently FPS remains strong.

As far as I can see, self-shadowing is forced, that's why there are additional shadows on the legs, on the chest, etc. It was disabled for many models (notably human characters) in the original game.

Screenshot looks very nice. The only thing I'm worried about is the possibility of the "real" shadows from grates interfering with the old "fake" ones.

It seems to mess with the intended lighting.

They put cubemapped / textured lights wherever they wanted these grates to cast shadows. If some grates don't have shadows, I assume it's intentional on the part of the artists.

The game was simply not made with shadowmaps in mind; adding them has some weird side effects such as plunging Doomguy's face and half his legs into shadows here.

Question of taste I guess.

[Spike]

stencil shadows cannot cast through alpha-tested surfaces. either the _volume_ is shadowed, or it isn't. you'd need to generate geometry for the holes, which would be expensive. its not a case of whether the grates were intended to cast shadows or not, the engine was basically incapable of doing it.
the stuff with the dude looks like the new engine no longer supports whatever no-self-shadow flag doom3 had. stencil buffer or shadowmap, the algorithm should basically be the same (generate ss shadows, draw nss surfaces, add nss shadows, draw ss surfaces. hurrah for updaing 12 sides of a cubemap...).
so that part should at least be fixable.

grates/alpha-tested surfaces casting shadows will make an already-dark game even darker. might need to be restricted to custom/adapted content. I guess it depends how many other lights there are.

[jim]

Maybe self shadows could be only 50% dark of what they are now?

[dwere]

If some grates don't have shadows, I assume it's intentional on the part of the artists.

Or it was simply inconvenient with the tools they had at the time. The shadows drawn directly on light textures are pretty limited in what you can do with them.

I can think of two reasons why self-shadowing was originally disabled for human characters:

1. It looks like ass on faces.
2. Less shadows = more performance.

I don't think the first reason applies to shadowmaps as much as it applied to stencil shadows.

[leileilol]

Give how low poly Doom3 was, self shadowing would look very poppy and hard. Q3A had self-shadowing with cg_shadows 2 and it looked kind of horrendous.

Then again Shadowmap self shadowing also has its share of problems. I'm kind of sick seeing windowblind patterns scattered across arms and faces and the like because of a speed-based depth compromises.

They put that light texture on hundreds of lights in the game. It is just a matter of copy and pasting the light really. I have studied the original d3 maps very closely in the editor, and they paid a lot of attention to details like this.

Spike, they simply placed textured lights to create those shadows all over the game. They had a reason to not place them here. Probably to not distract from the animation and the video that play here, or from the dead marines that appear in this spot later.

You guys underestimate how much attention the artists paid to these things.

[dwere]

They had a reason to not place them here.

I'd say, that reason is the angle at which the light is emitted. It illuminates both the objects in front of the grate and behind it. Therefore, any shadow texture applied to it would be projected on the greebly "server" thing.

Sometimes it's just technical stuff.
