Goober5000andClaude Opus 5.5 d6c253bda3 light insignias using lights rotated into their frame of reference
light_apply_rgb works in the model's local frame, but nothing rotated the
lights into that frame before insignias were drawn: light_rotate_all() was
only called for the briefing and tech room lights, and even then it skipped
Static_light, the separate copies of the sun lights that light_apply_rgb
reads.  So the sun term used a stale, never-set direction and the point
lights were treated as if they sat at the model's origin.

Rotate the lights, including the sun copies, once the insignia's instance
is set up, and light each vertex at its actual position, which includes
the insignia's offset.

Goober5000andClaude Opus 5.5 52e5652624 store insignia normals per face, and light insignia faces with them
The insignia normal array was declared with the vertex limit, filled in by
face index, and read by vertex index.  An insignia with more than 81 faces
therefore wrote past the array, into the following insignia or, for the
sixth and final slot, past the insignia list into the rest of the
polymodel.  And the renderer lit each vertex with the normal of whichever
face shared its index, or with a zero normal (ambient light only) when
there was no such face.

A normal belongs to a face, so size the array by the face limit and light
all three corners of each face with that face's normal.

wookieejedi c23c69a538 Fix primary thruster glows rendering through geometry (#7805) 2026-10-01 11:18:58 -04:00
Goober5000andClaude Fable 5.1 b609a6857b Time an animated shockwave base texture like its glow map
A 3D shockwave's glow map already takes its frame from the shockwave's
elapsed time so the animation spans the shockwave's life.  Do the same
for an animated base texture, and skip the radius fade for it, since the
artist's frames then control the brightness the way they do for the glow.
A static base texture still fades with the radius.

Goober5000andClaude Fable 5.1 1bfa46eabe Restore the fade on unlit additive model draws
3D shockwaves pass `1 - radius/outer_radius` as the warp alpha, which `model_render_determine_color` turns into the material colour for additive draws.  Since a481999a2 (SamuelCho's OpenGL Code commit in August 2016), the model fragment shader has not multiplied the diffuse sample by that colour in the unlit branch, so the base texture stayed at full brightness and vanished abruptly.  The same path carries the warp effect's radius fade and the alpha of unlit transparent weapons.

Clamp the alpha before converting it to a byte, as the pre-2016 code did; thrusters pass 1.2, and without the clamp they would now render dim.

Goober5000andClaude Opus 5 519e3aef21 Fix three memory leaks and make the debug leak check accurate
Report leaks after static destruction via _CRTDBG_LEAK_CHECK_DF instead of calling _CrtDumpMemoryLeaks() at the end of main(), which incorrectly reported every global container as a memory leak.

Also fix the three remaining real leaks which were discovered after all the noise was cleared up:
- Mc_point_list was never freed, because its atexit cleanup was only registered by code that no longer runs.  But the list was only a temporary array of pointers used while building the collision tree, so remove it and have model_collide_parse_bsp_defpoints() copy the vertices directly into the tree's point list.
- model_batch_buffer's Mem_alloc copy was never freed.  But the copy is actually not necessary, so remove it and pass Submodel_matrices directly.
- Goal_target_names strings were only freed when the next mission was parsed, so the last mission's names leaked at exit.  Hold them in SCP_vm_unique_ptr so they are freed with the vector.

b26b9cf743 Add Vulkan rendering backend, with HDR10 output and raytraced shadows (#7554)
* Shadow overhaul round 2: PCSS, dynamic cascades, cockpit/instanced shadows

Squashed snapshot of lafiel/shadow_overhaul_2's continuation work
(d3922aa87..010f9d2d9), which has no separate upstream PR of its own.

* Add Vulkan rendering backend

Squashed snapshot of the Vulkan backend as vendored into this branch
(ce2d1e85f..6ce539463, authored by Mara van der Laan with build/CI
fixes by Taylor Richards). This work has its own upstream PR #7553
(notimaginative:vulkan-pr-new) and is not otherwise original to true-hdr.

* Add true HDR output, RT shadows, and PCSS shadows for Vulkan

Squashed snapshot of true-hdr's own integration work: true HDR
framebuffer output, wiring the shadow overhaul into the Vulkan
backend (raytraced + cascaded shadow maps), logging refactors, log
filter UI, and CI/build fixes.

* refactor: update Vulkan logging calls to use `nprintf` for scoped logging

* fix: correct shadow cascade count in Vulkan logging calls

* fix: fall back to PATH-resolved ccache when CCACHE_PATH is stale

CI hardcodes /usr/local/bin/ccache, but macOS runners on Apple Silicon
hosts install Homebrew (and ccache) under /opt/homebrew instead,
causing all four Mac configs to fail with "No such file or directory".

* Fix vulkan texture readback to correctly handle transparent pipelines

* Put the pixel swizzles into a util file

* OOB safety check

* Fix fog handling

* Fix MSAA in Vulkan

* fix: enable SMAA for vulkan

* adapt the post-processing AA shaders to hdr

* fix clang-tidy warnings: concatenate nested namespaces, static methods

pixel_swizzle.{h,cpp}: collapse `namespace graphics { namespace util {`
into `namespace graphics::util {` (modernize-concat-nested-namespaces).

VulkanState.h/VulkanDraw.h: getClearColor()/setClearColor() only touch
gr_screen and other globals, no instance state, so make them static
(readability-convert-member-functions-to-static) and drop the
top-level const on getClearColor()'s return type
(readability-const-return-type).

* fix clang-tidy warning

* Extend raytraced shadows to all directional lights

RT shadows previously only shadowed the first directional light in the
scene, even though multi-sun missions push more than one directional
light into the engine. The TLAS raytraced shadows query against is
already light-agnostic, so this extends both the deferred lighting
pass and the forward MODEL shader to shadow every directional light
(capped by a new Max Raytraced Shadow Lights option, configurable via
the in-game Options menu or the Lab's Scene rendering options).

Cascaded shadow maps are untouched: they're built for a single light
only, so the deferred pass still limits itself to one shadowed
directional light whenever CSM (not raytracing) is the active method.

* refactor: improve shader flag handling and render target finalization in Vulkan backend

- Consolidate shader flag setup logic in VulkanPostProcessingLighting to simplify configuration.
- Fix dead field usage in VulkanDraw by ensuring correct image view selection for environment maps.
- Add mip chain regeneration in VulkanRenderer::endRenderTarget to ensure correct mip levels for cubemaps.

* fix: ensure correct mip chain initialization in cubemap rendering

- Add mip chain generation to VulkanDraw for cubemaps with multiple mip levels.
- Fix potential issue with uninitialized mip levels above level 0 in deferred-f.sdr sampling paths.

* fix: don't crash on startup when environment locale is unavailable

std::locale("") pulls in the process's environment locale categories
(LC_CTYPE, LC_MONETARY, LC_PAPER, etc.), and throws std::runtime_error
if any of them names a locale not installed on the host (e.g.
mismatched regional-format overrides). Since SCP_default_locale is
constructed during static initialization, before main() and before any
of our own exception handling exists, an uncaught throw here aborted
the whole process before the game even started. Fall back to the
classic "C" locale instead, which is sufficient since this locale is
only ever used for ASCII case-folding (SCP_toupper/tolower/isdigit).

* Ensure memory flushes after UBO updates and add explicit pipeline barrier for MoltenVK compatibility.

* fix: add clear pass for SMAA edge detection to prevent persistent artifacts

* feat: add Vulkan debug-utils messenger, opt-in sync validation, frame diagnostics

Groundwork for the renderer-review fix series (.agents/plans/
vulkan-renderer-review-fixes.md, Phase 0):

- Register a VK_EXT_debug_utils messenger (preferred) instead of only the
  deprecated VK_EXT_debug_report callback, which is kept as a fallback for
  loaders without debug-utils. The messenger config is also chained into
  instance creation so vkCreateInstance-time messages are captured.
  Validation errors/warnings now go to the main log via mprintf.
- New -gr_sync_validation cmdline flag (implies -gr_debug): chains
  VkValidationFeaturesEXT with synchronization validation into instance
  creation when VK_LAYER_KHRONOS_validation is available. This is the
  regression net for the synchronization fixes in the following commits.
- Frame stats now report descriptor sets/writes allocated per frame and the
  total pipeline count (descriptor-manager counters; DescriptorWriter::flush
  moved out-of-line to report into the manager).

* refactor: unify Vulkan render-pass begins, clamp in-pass clears, add per-frame UBO ring

Phase 1 of the renderer-review fix series: shared helpers that the
correctness fixes build on.

- New VulkanRenderer::beginTrackedRenderPass(PassBeginDesc): every render-pass
  begin on the frame command buffer now records vkCmdBeginRenderPass and
  updates the state tracker (pass, color attachment count, sample count,
  render area, viewport) in one place. Converted: setupFrame,
  beginSceneRendering (both branches), resumeSceneRendering,
  endSceneRendering, beginRenderTarget (viewport kept for gr_set_viewport),
  resumeSwapChainPass, plus new resumeScenePassAfterCopy() shared by
  copyEffectTexture/copySceneDepthForParticles and
  rebeginSwapChainPassAfterReadback() shared by both readbackFramebuffer
  exits (~200 lines of duplicated begin/clear/viewport blocks removed).
- The state tracker records the active render area; all four
  vkCmdClearAttachments sites clamp their rects against it and skip empty
  results. Previously gr_screen-sized clear rects could exceed a smaller
  off-screen render target's render area, which is invalid API usage.
- New PerFrameUboRing utility (VulkanPerFrameUbo.h/.cpp): a persistently
  mapped uniform buffer with one slot region per frame in flight and a
  self-flushing alloc(). Used by the next commit to fix the cross-frame
  UBO races.

Deliberate behavior deltas (all safe-direction): the helper always sets
colorAttachmentCount/sampleCount (some sites previously inherited stale
values), and resumeSwapChainPass/resumeSceneRendering now also reset the
standard flipped viewport instead of leaving the previous one.

* fix: eliminate Vulkan cross-frame UBO/buffer races, make gr_sync honest

Phase 2 of the renderer-review fix series: with two frames in flight, several
host-visible resources were rewritten by the CPU while the previous frame's
GPU work could still be reading them.

- The post-processing scratch UBO is now a PerFrameUboRing (per-frame-in-
  flight slot regions, persistently mapped, self-flushing alloc). All the
  per-pass map/unmap/cursor bookkeeping in bloom/LDR/fog/SMAA is deleted;
  the cursor resets exactly once per frame via the new
  VulkanPostProcessor::beginFrame() hook in setupFrame.
  This also fixes two latent bugs: (a) fog consumed scratch slots mid-scene
  and bloom's later same-frame cursor reset overwrote them before submission
  whenever fog+bloom were both active; (b) volumetric_fog_data (288 bytes)
  overflowed the 256-byte slots - the memcpy spilled into the neighboring
  slot and the shader's bound range ended before the aspect/fov/noise
  fields. Slots are now 512 bytes (static_assert at the fog call site) and
  the per-frame budget is 32 slots.
- The dedicated tonemap, output-encode, and MSAA-resolve UBOs (each a single
  instance rewritten per frame, i.e. racy; the MSAA one also never flushed)
  are deleted entirely - those passes build their structs on the stack and
  allocate from the scratch ring.
- Static-buffer rewrites orphan instead of racing: getVkBuffer() stamps a
  last-used frame number, and a full-content updateBufferData() on a Static
  buffer used within the last MAX_FRAMES_IN_FLIGHT frames defers the old
  VkBuffer to the deletion queue and writes a fresh one. Offset writes
  (GPU-heap appends to fresh regions) and PersistentMapping buffers (the
  engine holds their mapped pointer and syncs via gr_sync) are exempt.
- gr_sync_wait now honors its contract: VulkanRenderFrame::waitForFinish
  takes a timeout and reports expiry without consuming the fence;
  VulkanRenderer::waitForFrame returns false for fences taken during the
  still-recording frame (previously it waited on a stale or idle slot and
  reported success) and resolves the frame->slot mapping correctly. This
  makes UniformBufferManager's segment-fence throttling actually protective
  on Vulkan for the first time.

External weapon model cleanup: consolidate duplicated logic, fix several longstanding bugs
2026-07-20 23:40:35 -04:00
Goober5000andClaude Fable 5 7b241812ed make ship move-correct
Ship's implicit move operations compiled but were semantically broken in
two ways: moving copied the subsys_list sentinel's links verbatim,
leaving the bookend nodes of the intrusive subsystem list pointing at
the old sentinel address; and the raw owning warpin_effect /
warpout_effect pointers were copied without nulling the source, so a
vacated Ships[] slot aliased live WarpEffects that ship::clear() (on
slot reuse) or ship_close() (which walks every slot) would delete out
from under the destination ship.

Fix both at the member level so the compiler-generated moves are
correct by composition:

- Add ship_subsys_sentinel, derived from ship_subsys, whose move
  operations re-link the bookend nodes (handling the null-linked,
  self-referential-empty, and populated source states) and leave the
  moved-from sentinel as an initialized empty list.  Copying is
  deleted.  Public inheritance keeps &ship::subsys_list convertible to
  ship_subsys*, so list_init, GET_FIRST, and every other call site is
  unchanged.

- Convert warpin_effect and warpout_effect to std::unique_ptr.  The
  delete-and-null blocks in ship::clear(), ship_close(), and
  ship_set_warp_effects() collapse into reset(); call sites that borrow
  the pointer into a raw local now use get().

With the members handling themselves, declare ship's special member
functions: defaulted default constructor and moves, deleted copies
(previously implicit via the unique_ptr members, now stated intent).
The moves are deliberately not declared noexcept because members like
SCP_map and std::deque do not have standard-guaranteed nothrow moves;
the computed exception specification is used instead.

Goober5000andClaude Fable 5 da24cdae38 store glowpoint override indices instead of pointers
glowpoint_bank_override_map stored raw pointers into the growable global glowpoint_bank_overrides vector.  Store indices instead, which survive vector reallocation.  The readers also lose a redundant second map lookup (they previously called find() and then operator[] on the same key), and prop_info's parallel map gets the same conversion.

Goober5000andClaude Fable 5 6578217008 revive $Weapon Model Draw Distance; fix attached weapon model LOD depth
The draw-distance cull for attached external weapon models checked
MR_ATTACHED_MODEL, but nothing has set that flag since commit
1ef7688fa1, so $Weapon Model Draw Distance: has been dead for years.
The check also needed the ship resolved from the render params' object
number, which is deliberately not set while weapon models render
(setting it would make model_render_queue clobber the explicitly
passed gatling model instance), and it compared against a depth
computed as if the weapon model's ship-local position were in world
space.

Carry the distance in model_render_params instead
(set_attached_model_draw_distance, negative = not an attached model),
set by ship_render_weapon_models from the ship's tabled value.  When
set, model_render_queue measures depth from the eye position expressed
in the parent's frame (model_draw_list::get_view_position), which is
correct under the pushed parent transform, culls against the tabled
distance, and uses that same corrected depth for detail level
selection -- previously attached weapon models picked their LOD from a
garbage depth (roughly the eye's distance from the world origin).

MR_ATTACHED_MODEL is removed; nothing else referenced it. The unused
flags are also removed and the remaining flags are consolidated.

Goober5000 ee50cde0e1 more robust handling of modelinstance teardown
Set model instances to -1 when objects are deleted, and guard against null model instances in `modelinstance_replace_active_texture`.  This may fix a crash in Event Horizon.

BMagnuandGoober5000 20c8417e8b Fullneb Revamp (#7352)
* change to new fog system

* Fix fog conversion issues

* remove unused old neb values

* Update scripting API

* temporary old-value round trip

* Rewrite nebula fog with four explicit parameters

Replace the legacy `+Fog Near Mult` / `+Fog Far Mult` model — which
depended on fixed engine constants — with four parameters that map
directly to renderer behavior:

  +Fog 1000m Visibility    fraction of light surviving 1000m of fog
  +Fog Near Distance       meters from camera where fog begins
  +Fog Skybox Clip Distance  max render distance for the skybox in fog
  +Fog Clip Distance       max render distance for the scene in fog

The deferred-lighting fog shader, material system, model renderer,
object sort, and the Lua mission API all consume the new parameters
directly. The legacy `Neb2_fog_near_mult` / `Neb2_fog_far_mult`
globals are removed.

Mission parsing accepts either the legacy keys or the modern keys.
Legacy values are converted to the modern set at parse time, and a
per-mission flag (`Neb2_fog_use_legacy_values`) records which keys to
write back on save. The flag is cleared only when something actually
changes, so opening and OK'ing an unmodified legacy mission preserves
its on-disk format. Saving uses `optional_string_fred` to preserve
user comments through edit cycles.

FRED2 and QtFRED background editors both expose the four parameters
in place of the old multipliers, with friendly labels and tooltips.
Both editors validate input (visibility clamped to [0, 1]; near
distance must be > 0; skybox and scene clip distances may be 0 to
disable fog at that range) and use a snapshot-and-compare at close
time so that a no-op open-then-OK never spuriously rewrites a legacy
mission in the modern format.

FRED2's background dialog is also reorganized so that "Display bg
bitmaps in nebula", "Override nebula fog palette", the RGB row, and
the four fog parameters all sit inside the Nebula group box; the
"Old Nebula" group box is restored below it with its Pattern, Color,
Pitch, Bank, and Heading controls back inside the frame. The dialog
now overrides PreTranslateMessage so that the new fog tooltips —
and the previously broken "Save sun/bitmap angles in correct format"
tooltip — actually fire.

QtFRED's BackgroundEditor.ui adds four QDoubleSpinBox controls in
the existing nebula form layout, with per-field decimals chosen to
avoid scientific notation, and per-field min/max declaring the
validation rules. The QtFRED help page is updated to describe the
new fields.

* fix tooltips

* restore forward-renderer fog

* Clang Tidy

* address feedback

* Refine nebula fog rewrite

- Rename Neb2_fog_use_legacy_values to Neb2_fog_save_legacy_values
  to reflect that the flag governs save format, not runtime
  behavior.
- Decide both the save flag and the legacy-to-modern conversion
  purely from whether the file contains modern fog keys, dropping
  the prior heuristic based on required_fso_version. A mission
  without modern keys (legacy- or retail-format) converts on load
  and saves back in legacy format; missions with modern keys are
  saved as modern.
- Snapshot the four fog values as floats at editor open and use
  fl_equal for the no-change comparison in both FRED2 and QtFRED,
  replacing the FRED2 CString comparison and the QtFRED strict
  inequality.
- Document the on-disk invariant in missionsave: when not saving
  legacy keys, the four modern keys must always be written (never
  gated on "only if non-default"), since the parser uses their
  presence to decide whether to run the conversion on next load.

wookieejedi 2ec1553898 Fix few small bugs (#6755)
* Fix two small visual-based bugs

PR fixes/cleans up two small visual bugs/clean-up aspects.

1) If a mod uses the autoaim frame feature of the center reticle (IE the center reticle switches to a second bitmap if a target is within the autoaim cone), then there is currently an edge case bug where if the player's target dies while in the autoaim cone, the value tracking whether or not to use the autoaim frame is never reset to false. This results in the autoaim frame remaining even when the target is dead and long destroyed. This PR properly resets the autoaim bool to false if the target is not valid, and overall works now as expected.

2) #6555 moved warp options to tables instead of via in-game options, but there was a line of code that still referenced `WarpFlash`, where that option was forced off in standalones. This PR properly removes that line and instead puts the standalone check as part of the input warp queue function.

* also cleanup techroom subsystem loading

wookieejedi c6f2d05998 Allow normal, AO, and misc maps at higher detail settings (#6658)
Previously, FSO did not show normal, AO, or misc maps at LODs 3 or higher. This was  a relic from original retail days, so this PR allows players to see those textures if the model detail level is at 3 or 4. I put this under the model slider because it is related to LODs, and b/c changing the model slider is something folks actually use compared to the other hardware tex slider which really makes things look ancient if turned to anything other than the max.

Goober5000 ca624f86e2 a few pstypes changes and refinements
Several changes related to the volumetrics model fix:
1. Update the `model_load()` prototype with better parameter names, including a new `ErrorType` enum defined in pstypes.h
2. Update the `MIN`, `MAX`, and `CLAMP` macros, all of which were susceptible to performance issues because they duplicated their tokens.  This could cause functions or calculations to be re-run unnecessarily.  Since the codebase is now on C++17, `std::clamp()` can be used.
3. Update the rest of the codebase to fix any associated issues.
