Added framework to do texture animations entirely in C++. Currently only
works on relatively simple ones, and doesn't handle updating all
parameters - only the speeds.
Connected texture animations to merc and tfrag for skull gems, dark
bomb, and scrolling conveyors.
Cleaned up Tfragment/Tfrag3, which used to be two classes. This was one
of the first C++ renderers, so it had a weird design.
This moves the blerc math from mips2c to the Merc2 renderer, and uses
floats instead.
We could potentially do this on the GPU, which would be even faster, but
this isn't that slow in the first place.
- decompile `neon-baron-part`, which also has the hideout door for some
reason
- improve a few error messages in static data decompilation
- fix bug with disabling fog in merc
- better handling of the `disable-fog` settings for merc, should fix the
spotlights. There's a setting in the merc effect, and also a runtime
flag for the draw-control. I'm not actually sure what reads these, but
the draw-control one is definitely used to disable fog on the
spotlights.
- increase merc draw limit to try to fix the issue about partially drawn
citizens in the city
- remove useless debug prints (it's okay to die in init, and the medium
load buffer size mode is understood now)
Fixes some mistakes with merc draw modes. The glass in the palace level
no longer writes to the depth buffer (it's "water"):
Also fixes the one-frame flickers when level draw orders change. We
might be able to make this more efficient in the future, but this will
at least fix the frame with nothing drawn.
Three main changes:
- Adds support for the texture scrolling effect used on conveyor belts,
and turn it on for jak 2.
- Use merc instead of generic in jak 1 for ripple/water/texscroll stuff
(non-ocean water, lava, dark eco, etc). This is a pretty big speedup in
a lot of places.
- Fix a really old bug with blending mode used to draw environment maps.
The effect is that envmaps were half as bright as they should have been.
As usual, there's a flag to go back to the old behavior on jak 1. Set
these to `#t` to use generic like we used to.
```
*texscroll-force-generic*
*ripple-force-generic*
```
The format has changed, and everything must be rebuilt (C++, FR3's, GOAL
code)
Support rendering eyes with merc for both jak 1 and jak 2.
For jak 1, everything should look the same, but merc will be used to
draw eyes. This means that jak is now fully drawn with merc!
For jak 2, eyes should draw, but there are still a few issues:
- the tbp/clut ptr trick is used a lot for these eye textures, so
there's a lot that use the wrong texture
- I had to enable a bunch more "texture uploads" (basically emulating
the ps2 texture system) in order to get the eyes to upload. It would be
much better if the eye renderer could somehow grab the texture from the
merc model info, skipping the vram addressing stuff entirely. I plan to
return to this.
- I disabled some sky draws in `sky-tng`. After turning on pris2
uploads, the sky flashed in a really annoying way.
This PR adds a feature to merc2 to update vertices. This will be needed
to efficient do effects like blerc/ripple/texture scroll. It's enabled
for blerc in jak 1 and jak 2, but with a few disclaimers:
- currently we still use the mips2c blerc implementation, which is slow
and has some "jittering" because of integer precision. When porting to
PC, there was an additional synchronization problem because blerc
overwrites the merc data as its being read by the renderers. I _think_
this wasn't an issue on PS2 because the blerc dma is higher priority
than the VIF1 DMA, but I'm not certain. Either way, I had to add a mutex
for this on PC to avoid very slight flickering/gaps. This isn't ideal
for performance, but still beats generic by a significant amount in
every place I tested. If you see merc taking 2ms to draw, it is likely
because it is stuck waiting on blerc to finish. This will go away once
blerc itself is ported to C++.
- in jak 1, we end up using generic in some cases where we could use
merc. In particular maia in village3 hut. This will be fixed later once
we can use merc in more places. I don't want to mess with the
merc/generic selection logic when we're hopefully going to get rid of it
soon.
- There is no support for ripple or texture scroll. These use generic on
jak 1, and remain broken on jak 2.
- Like with `emerc`, jak 1 has a toggle to go back to the old behavior
`*blerc-hack*`.
- In most cases, toggling this causes no visual differences. One
exception is Gol's teeth. I believe this is caused by texture coordinate
rounding issues, where generic has an additional float -> int -> float
compared to PC merc. It is very hard to notice so I'm not going to worry
about it.
This adds environment mapping support to `Merc2`, and turns it on for
Jak 1 and Jak 2.
- The performance is much better
- Jak 1 can be toggled back to the old behavior with `(set! *emerc-hack*
#f)`. The new environment mapping is identical to the old one everywhere
I checked.
- Jak 1 still falls back to generic for ripple/texscroll/blerc/eyes -
there's still no dynamic texture or vertex updating support. The eye
detection stuff will sometimes flag stuff as eyes which is not eyes,
which is fine, but means that generic will be used in some places where
emerc could be used. For example, the shiny plates on jak's arm will be
drawn with generic because jak has eyes.
- Jak 2 hasn't been checked super carefully against PCSX2 yet.
- Jak 2 still isn't technically using emerc, but instead putting emerc
models in the merc bucket.
- The interface to merc is a lot different now and totally custom
OpenGOAL DMA code. The original merc drawing asm doesn't run anymore.
- The FR3 format changed
- Something funky going on with foreground lighting in escape, but
doesn't seem to be related to this change?
Performance comparison, jak 1, in likely the most generic-merc heavy
spot:
- make sure bsp is processed on `l` levels in extraction (caused missing
remaps)
- clean up a few prints in extraction
- handle the <15 byte differences in art group files automatically (no
more errors about file naming)
- fix potential exception thrown by merc2 in a few ways: fixed bad data
in FR3's, check texture index just in case, and handle exceptions a
little bit better (still a crash, but at least you get a print)
- fix mips2 ocean stuff causing ocean far crashes
Favors the `lg` namespace over `fmt` directly, as this will output the
logs to a file / has log levels.
I also made assertion errors go to a file, this unfortunately means
importing `lg` and hence `fmt` which was attempted to be avoided before.
But I'm not sure how else to do this aspect without re-inventing the
file logging.
We have a lot of commented out prints as well that we should probably
cleanup at some point / switch them to trace level and default to `info`
level.
I noticed the pattern of disabling debug logs behind some boolean,
something to consider cleaning up in the future -- if our logs were more
structured (knowing where they are coming from) then a lot this
boilerplate could be eliminated.
