I finally went through and worked out the math for the camera matrix,
and improved how it works for PC rendering. I was able to finally avoid
the double perspective divide issue, which I always thought would cause
accuracy issues.
This will help tfrag, tie (no envmap), shrub, and hfrag have less
z-fighting in cases where the camera and the thing you're looking at are
pretty close, but the entire level is far from the origin - like jak 3
temple. I was able to modify the camera matrix so we don't have to do
all the weird scaling/addition in the shader.
Here's a screenshot from the temple oracle checkpoint, cropped from 4k.
This used to have a lot of fighting issues.
It doesn't help issues where the thing you're looking at is very far
away (jak 1 mountains, some jak 2 city stuff). It also doesn't help with
jak's skirt/scarf, since those use a different renderer.
There's definitely more to do here, but this is a good starting point
and proof that I can at least figure out the math.

In Jak 3, the default PC settings file would have a language of 255
because it runs before the first settings update. This would cause the
game to crash the second time it is started.
I also added this simple imgui window to see the names of streams in the
"SPU" memory, which has been useful for debugging

Two new flags were added to the Blender plugin to allow reusing the mod
and/or eye draws of the original model that is being replaced. Works
pretty well for eyes, but the blerc draws can cause some Z-fighting with
the non-moving parts of the model.
Also a small refactor to the merc replacement code to de-duplicate some
code by moving stuff to `gltf_util.cpp`.
Fix compiler warnings, and a bug where the `snd_handle` of
`SoundBankInfo` was never set, leading to sound banks never unloading.
The game relies on unloading soundbanks to make sure certain sounds
don't play, like the blue gun 1 fire noise when using blue gun 2.

The fundamental issue is related to hiDPI / Retina displays, I don't
think our rendering code is setup properly to handle the scaling between
the two (which you can derive by comparing `SDL_GetWindowSize` and
`SDL_GL_GetDrawableSize`).
So rather than opening that can of worms, I just removed the window
flag.
Also fixed an unrelated issue for displaying resolution options when in
windowed mode, it was previously only adding options to the list if they
were invalid for full-screen.
Fixes#3099
Fixes a regression in #3722.

This is so I can get rid of wgpu from the launcher, where it's only
purpose is to figure out the GPU name for the support package.
The problem with it is that on some environments, it errors, but the
function cannot have it's errors gracefully handled (it panics and
crashes instead).
So I'm tired of it, do it ourselves.
Fixes issue with not handling texture flipping flags in sprite renderer
(new jak 3 feature). As far as I can tell, there is no visible
difference because the textures that use this flag are symmetric.
Fix issue with not adding an `and` with `0xf` on the offset into the xy
table. This is added only in jak 3, where `vi07`'s upper bits are
sometimes nonzero, but doesn't hurt to have in all three games.
```

This only applies to the background for now:
- support for alpha for vertex colors in custom levels
- switch time of day palette generation from octree to k-d tree
- support for alpha masking in custom levels
- support for transparent textures
- support for envmap in custom levels

This attempts to do a best-effort quick fix for the sprite alignment in
the menus and first person views on higher aspect ratios. This:
- Hides the binocular borders completely when using a non-standard ratio
- Hides the borders in jak's first person view when using a non-standard
ratio
- Uses a combination of manual alignment and approximation to get the
pause menu closer.
> 32:9 screenshot.
I accomplished the last one by manually aligning all of the core sprites
and text for the most popular aspect ratios. This means that from a
practical standpoint, things should align "perfectly". However, I then
used all of those values to derive a polynomial for each adjustment
based on the aspect ratio. This allows the game to do a half-decent
approximation/interpolation for every aspect ratio in-between the common
ones. It won't be perfect, but it will be better than this:
A few minor fixes:
- Fix crash in overlord3 during final boss
https://github.com/open-goal/jak-project/issues/3605
- Update goal_src for `scene-actor.gc`, which was not updated after a
bug fix for decompiling skelgroups, making some cutscene actors
invisible due to using the wrong joint for culling checks.
- Stop using `-1` as an invalid value for texture id's in Merc.cpp. This
could sometimes cause Merc2.cpp to accidentally skip updating the OpenGL
texture. This fixes the bug where skull gems sometimes didn't have the
animated textures.
I found two issues with Jak 3 eyes. The first was simple - we were
missing a `-pc` texture upload in `texture.gc` for `pris2` textures,
which has eye textures for a few characters, like torn or damas.
The second was a little more annoying. Unlike jak 2 and jak 1, jak 3 can
dynamically assign eye slots when merc models are loaded. This involves
modifying eye data to tell the eye renderer where to render, and
modifying the merc model's adgif shaders to point to the correct eye
texture. The modification to the merc adgif shader is problematic since
our PC port of merc assumes this slot is constant.
My solution here was to bypass this whole slot system entirely for jak
3. I modified the GOAL eye renderer to tell the c++ eye renderer the
name of the merc-ctrl containing the eye. Then, the PC C++ Merc renderer
can just look up the merc-ctrl by name. To make this fit nicely in the
existing memory layout, I used a 64-bit fnv hash of the name. (which
honestly is how we should have handled a lot of other texture/model
names stuff...)
Unrelated fix to Overlord2 so it handles the case where file size
changes after the game starts, I had this in jak2/jak1 and forgot it for
jak 3.
This adds support for replacing existing merc models in FR3 files with
custom GLB model files. The replacements go in
`custom_assets/<GAME>/merc_replacements`, similar to texture
replacements. When a `.glb` file with a file name that matches any model
present in an FR3 is detected (e.g. `eichar-lod0` for Jak), all merc
model data is replaced with the given model.
Additionally, models for custom actors can now also be added to vanilla
FR3s. The models for this go in
`custom_assets/<GAME>/models/<LEVEL_NAME>` (e.g.
`custom_assets/jak1/models/jungleb/test-actor-lod0.glb`) and will be
added to the FR3 that has a matching name (exception: to add things to
the common level file, the folder should be named `common` instead of
`GAME`).
For custom levels, these now go in
`custom_assets/<GAME>/models/custom_levels` (previously
`custom_assets/<GAME>/models`).
Another small change: When level ripping is enabled, the resulting model
files will now be stored in game name subfolders inside of `glb_out`.
- Can make the event buffer larger or smaller
- UI shows the current event index / size, so you know how fast it's
filling up
- Can save compressed, 10x reduction in filesize and Windows 11 explorer
actually supports ZSTD natively now so this isn't inconvenient at all
> An example of almost 1 million events. Results in a 4mb file.
This adds support for generating collide meshes when importing custom
models. A couple of things to keep in mind:
- A single `collide-mesh` may only have up to 255 vertices.
- When exporting a GLTF file in Blender, a `collide-mesh` will be
generated for every mesh object that has collision properties applied
(ideally, you would set all visual meshes to `ignore` and your collision
meshes to `invisible` in the OpenGOAL plugin's custom properties).
- Ensure that your actor using the model properly allocates enough
`collide-shape-prim-mesh`es for each `collide-mesh` ([example from the
original game that uses multiple
meshes](https://github.com/open-goal/jak-project/blob/f6688659f2ef85f5ceaacea6271580c9f4d91ed1/goal_src/jak1/levels/finalboss/robotboss.gc#L2628-L2806)).
~One annoying problem that I haven't fully figured out yet (unrelated to
the actual functionality):
`collide-mesh`es are stored in art groups as an `(array collide-mesh)`
in the `art-joint-geo`'s `extra`, so I had to add a new `Res` type to
support this. The way that `array`s are stored in `res-lump`s is a bit
of a hack right now. The lump only stores a pointer to the array, so the
size of that is 4 bytes, but because we have to generate all the actual
array data too, the current `ResLump` code in C++ doesn't handle this
case well and would assert, so I decided to omit the asserts if an
`array` tag is present and "fake" the size so the object file is
generated more closely to how the game expects it until we figure out
something better.~
This was fixed by generating the array data beforehand and creating a
`ResRef` class that takes the pointer to the array data and adds it to
the lump.
For now, this just adds sky (clouds and fog), darkjak, and skull gem.
There are some unknown issues with drawing the skull gems still, but I
think it's unrelated to texture animations.
Also fixes https://github.com/open-goal/jak-project/issues/3523
This adds hfrag, but with a few remaining issues:
- The textures aren't animated. Instead, it just uses one texture.
- The texture filtering isn't as good as at it could be.
I also cleaned up a few issues with the background renderers:
- Cleaned up some stuff that is common to hfrag, tie, tfrag, shrub
- Moved time-of-day color packing stuff to FR3 creation, rather than at
level load. This appears to reduce the frame time spikes when a level is
first drawn by about 5 or 6 ms in big levels.
- Cleaned up the x86 specific stuff used in time of day. Now there's
only one place where we have an `ifdef`, rather than spreading it all
over the rendering code.
This fixes issues with certain Jak 3 levels not rendering because there
is a mismatch between the DGO name, nickname and real level name (bsp
name).
FR3s use a different filename, so you can delete the ones you have after
this is merged.
This affects custom levels, but I don't have that toolchain set up so
someone else will have to test that.
This is primarily driven for proper mod-support. Mods would like to
isolate their settings and saves (potentially) and that is currently
done by find-and-replacing code before building. Bad!
Additionally, this has the side-effect of allowing for portable
installations of the game so, win-win.
Testing in progress, i'll merge once it is ready.
