aeonios added a comment to D2143: prevent tree leaves from showing up as white in reflections.

Should be doable by having the darkness of the reflection affect the fresnel. A problem is that reflection should be seen as additive, where as right now we mix both.

aeonios added a comment to D2143: prevent tree leaves from showing up as white in reflections.

Your solution is honestly probably more correct. I figured out that the issue was due to translucency, although I still haven't figured out any way to get realistic levels of contrast in the reflections. :\ Real reflections tend to be very high contrast, particularly wrt shadows.

Oh. In that case it might be worthwhile to do more tuning with early exit, and possibly find the optimum value for using RangeOp.

The object-oriented programming should not be hidden from the author, the author should rather become used to it. It's one the core design aspects of the rmgen system to be able to use different prototype instances implementing the same interface interchangably.
Yes it requires typing some more characters (new AvoidTileClassConstraint() vs avoidClasses()), but the alternative means spamming the libraries with random proxies.
The mapscripts should be as easy to write as possible, but not at the cost of introducing proxies in the library. The library should be as concise as possible while maintaining its features.

My preferred language is java. :\ I still prefer the factory methods in this case, but I guess I don't necessarily have to do everything in rmgen. An alternative library seems like a better option at this point, because we're definitely not going to agree on very much.

That 6s performance is achieved by nuking the 27 already IIRC

Do what?

Replace the number 27 with 0 in TileClass.js so that RangeOp is always used

Ok, I can pretty much guess what that involves. Seems like an easy win. I bet that early exit could be used there as well, but it'd need similar tuning to ensure that it's only used where it's likely to be profitable. On the other hand, the difference with early exit only seems to be fractions of a second when using RangeOp so it's probably not worth the effort. :P

The main reason I switched things around the way I did was to cut down on verbosity. You no longer have to type "new" all the time and instead of typing "AvoidClassesConstraint" you just type "avoid:". That's also why I made them constants, because nothing is a bigger PITA to type than freaking quotes.

aeonios added a comment to rP22310: Fix red squares on some maps when using HQ water effects.

Partially because of scissoring #2692, but also we have inaccurate refraction projection (inaccurate in relation to the real refraction angles). We may calculate it more carefully.

There really isn't a better way of doing that. Any given approximation of refraction isn't going to be much different from what we've got.

Yeah, I found the 6-36 thing hard to believe too. Way less and faster iteration and way more efficient cpu cache usage might be the reason. The significantly JS typed arrays would have something to do with it too.

You should submit this. Seriously. Going from 36 to 6 is going from O(n^2) to O(n).
What I don't understand is why early exit is performing worse on certain things. :\ It should generally lead to fewer iterations or else have no effect at all.

Yes, there is currently no need for finding the exact number of points in a radius. But a density constraint may not be the only use case. Smarter coordinate picking for random placers could also be a thing.

They wouldn't be very 'random' then, now would they? Doesn't matter, if there's a good use case for it we can just write a function for it. No sense having the feature for uses that don't require it, particularly if it costs more.

But, I guess if it helps, there is no reason to keep dead code around.

I see what you mean here. I mean I guess you could place things based on tile class density, but the current usage only uses geometric measures. If there were an actual need for that we could just add extra functions for it.
At the moment I don't see a real reason for using density-based constraints though.

For all the people who have spent countless hours messing with this, that is only partly true. The last point is only true in a subset of map designs. (Jebel Berkal a prime counter-example)

It's true for most maps that aren't Jebel Berkal.

Most importantly, early-returning is entirely pointless when you have done other optimizations. See that tileclass thing lying around which have promising results. Those results could be matched and even faster at times without losing a feature that have interesting use cases.

I don't think so. Even with all the other optimizations this can still represent a significant speedup. Also there were no features lost by this. The behavior is exactly the same, only faster in a lot of common cases.
I mean literally all the function does is say "yes this location meets the requirements" or "no this location doesn't meet the requirements". That's all it ever did, except that it did so more wastefully before since it would keep calculating even after success or failure had already been established.

Or rather the problem, nor the setting change are reported at all (barring the unreadable barely noticeable openGL mainlog error).

I sort of fixed that in my unrelated shadow revision. Sort of. The error is still reported via the GL error text, but I made it more understandable and just had it recursively reduce the size until it allocs properly or fails completely. Also the settings GUI won't update until you close it and open it again even after the resolution has been reduced by the backend code if/when it fails. I don't think there's any way around that due to the way the settings panel works.

aeonios added a comment to D1588: [Atlas] Allow returning to current selection to place objects .

I think the real issue here is the lack of a proper "place object" cursor mode. If you select an object to place then you get an object placement cursor, but if you switch to anything else then there's no way to get back the object you were placing except to select some other object first to get the object placement cursor back, then switch to the object you actually wanted. Most of the other cursors have proper modes so if you switch to a mode you get whatever it was you were last using with it, but object placement doesn't have any indicator that that's what you're even doing until you start moving the cursor around and see the object on it.

I replaced the tileclass member counting function used by constraints with a function that returns either true or false, using early exit for success/failure depending on the type of query. The early exit should moderately reduce the cost of constraints checking, which is probably the largest single cost for generating maps.

  • Most of the camera options are broken in the engine. They do not work and need to be fixed or perhaps just implemented before these options will do anything.
  • You'll need scripting hooks to the camera control settings engine side in order for changes to options to have any effect without restarting.
  • Tilt up/down using the (control+) scroll wheel would be nice. Currently it's not implemented and due to the peculiarities of scroll wheel controls it doesn't work if you try to set regular tilt up/down to use the scroll wheel.

It seems most maps are just different combinations of randomized resources lakes and hills and only differ at textures and models.
What I like to see for 0 A.D. are truly unique maps that are entirely different than every other map. Ambush in Alpha 19, Red Sea, Mediterranean in Alpha 20, Danubius and Extinct Volcano in A21, Jebel Barkal, Elephantine, Lower Nubia, Hellas in Alpha 22 for instance.
(There are considerably many players who just want mainland forever though)

Most of the maps aren't very random at all. They use a very strict construction formula that basically only differs in the number of players placed on the map. A lot of the maps you mention here have terrible gameplay as well. Mediterranean is bad in every imaginable way. Extinct Volcano is hideously ugly and the texture creates a false impression of cliffs and things where there are none. Aside from the city, Jebel Barkal is an extremely boring map, and also not applicable to ranked games. Elephantine is basically always the same map, nothing random about it. Same with lower nubia, with the additional problem that it's horribly imbalanced to the point of being unplayable for whoever gets stuck in the north. Hellas is kind of interesting but it often generates terrain that's extremely frustrating to play on.

I hadn't really thought about it, but you're right the mountain texture is pretty monotonous. I'll look into that next.

Btw, I see a little texture glitch (?) on the very first screenshot, left-side little to the bottom. The transition from snow to grass features two perfect straight lines and a perfect straight angle connects them (if you understand what I mean)

Eh, that's a limitation of the map generator interface. Ultimately I decided to split it back up into summer and winter variants rather than trying to get the snow and grass to mix in any sort of coherent way.

Also, it seems like you use only one texture for everything (so one snow texture, one grass texture etc). Maybe introduce a little more eyecandy there?

Yes I've already done a bunch of work in adding variety to the ground textures. It became more or less a necessity when splitting them into summer and winter.

This is a bad idea.

I reduced the big blur from 9 taps to 5 taps, which when using linear sampling uses the same number of samples as the 3-tap small blur. This allowed me to simplify the code by reusing the same code for both 3-tap and 5-tap blurs and just changing the offsets and weights. Visually you can't really tell the difference. I also reinstated using all 3 blur textures for bloom, since the smallest blur texture increases the sharpness of the bloom and makes it look a little better. Since that texture is already being sampled by the shader as long as dof is enabled it adds exactly zero overhead one way or the other.

Ok this is getting a major overhaul. I figured out how to implement PCSS for soft shadows and got it working, but that touches a million different files which will cause conflicts with my grand unified postproc shader revision, at least until that gets merged. For the moment I'm going to have to shelve this, but until all of that is sorted out, screenshots!

aeonios added a comment to rP21786: really fix packing problems reported in rP21630.

This doesn't really have much to do about packing or rP21630, it's changing the attack-move sub-orders from forced to not forced so units won't chase targets anymore.
In particular, units in defensive stance won't attack any units on the route until they're close enough to their destination. That doesn't seem correct to me, but I guess we'll see how many bug reports we get.

Usually what is done is that there is a number of ragdolls set by the engine. The way it could be implemented would be to iterate through all decaying entities and remove the one that have decaying for the longest until you reach the number set.

That'd probably be more expensive than just increasing the sink rate dependent on the number of corpses relative to the preferred max. Doing it that way doesn't require any extra iterations over the corpses and doesn't cause corpses to suddenly disappear.

Expensive is the pretty relative meaning. The blur is expensive too. How much the combining expensive? We need to choose between usability and performance.

The biggest cost, as with most postproc-type rendering, is in memory bandwidth. Both the blur process and the final combine are shared by bloom and dof. That means the blur process only needs to be performed once for both shaders (and blur can indeed be expensive, as in causes a noticeable slowdown if overused) and the combine can read the screen texture once and write it once for both shaders. Also, as I've mentioned, combining them allows the visual effect to be consistent whether applying just one of the effects or both. There's no loss of usability and you only pay for what you use. However if you use both you get a cost discount. DOF could support customization through atlas (ie distance factor, distance scale kind of like fog), but that's not immediately needed.

We use the javascript language for the game logic. It's expensive, but it allows many useful things. Deferred rendering is expensive, but it allows to calculate PSM with high precision, virtual textures, etc. Raytracing is expensive, but it allows nice AO.

True but getting the best visual effect for a given cost is always good.

Right now custom postproc effects are not actually supported by postproc manager, but that's beyond the scope of this revision.

It's not actually true, you can customize effects by editing a map file manually.

Eh? How? AFAIK you can't actually use custom shaders. You can configure effects that are already supported, but you can't set up custom textures or FBOs or manage the rendering process.

My point is to allow to artists/modders to freely edit effects. Why? Because if you will profile the game, you will notice, that postproc or final rendering don't cost a lot, the most expensive thing is object submitting. As you noticed we don't use instanced rendering, so we draw a lot of tries/units per different calls. So until we have the completely different bottleneck, we don't need to do optimizations that break usability too early.

There's nothing here that prevents map makers from customizing things just as well as they can do already. Well, at the moment they can't turn off DOF but it wouldn't be a large step to allow it and to even make it customizable. That's mostly a matter of atlas though and beyond the scope of this revision. If you give atlas the necessary capabilities I can certainly handle the backend support. This won't be live until at least a24 anyway so we've got time. The way postproc is handled with maps isn't really ideal, and only allowing one effect is rather limiting. Due to how bad DOF was before I don't think there are any maps that use DOF intentionally anyway.

But the BIG word doesn't mean something exact. Why not call it as I mention above (actualSize, fullSize, etc)?

"actualSize" and "fullSize" aren't any more meaningful either. One blur is a 3 tap gaussian blur and the other is a 9 tap gaussian blur. Both are gaussian blurs and both are "actualSize", but one is bigger than the other which is why I named it such.

How Postprocessing should work? An artist/modder has the Atlas or a text editor. He/she adds a list of different PP-effects (i.e. bloom, BW, cartoon) to a map and it works together. Effects are like components. So you don't have to do all things in the one file. And it'd be very good to choose an order of effects.
But if you don't know how to do it or don't want to do yourself, you can wait me. I plan to make changes to the Atlas to allow multiple effects with a different order.

You don't need to be compatible. You just need the same position and the same angle of the camera. You can hardcode it, or just use a simple cinemapath.

That'd be a lot of work. Way more than is justified for taking screenshots.

Ok so I got around to dealing with compatibility issues. The way maps interact with postproc is kind of a pain but I made it work as sensibly as I could.

I like this at all, but I have important notes:

  • Screenshots should be before/after, not just after. Also they all have the pretty same angle, that's not good for any comparison.

Someone apparently fixed the broken blur shader, but as you can see it's not exactly something that anyone would want to use on purpose.
