the-e 9443c4abe0 Add shadow contact hardening via PCSS blocker search
The shadow-mapped path's penumbra width was a fixed per-cascade value
(shadow_smoothness_scale()'s ceiling), so every occluder blurred its
shadow by the same amount regardless of how close it actually was to
the receiver -- unlike the raytraced path, which gets that for free
from traceShadowRayCone()'s real occluder distance. Close that gap
with PCSS: search nearby texels for occluders, then scale the filter
radius by how far away they were.

The blocker search (pcssBlockerSearch() in shadows.sdr) needs raw,
uncompared depth reads, which the existing PCF sampler can't do -- it's
bound with a compare mode for the hardware shadow-compare instructions
the filtered sampling itself relies on. So shadow maps now get a second
sampler, shadow_map_raw, bound to the same texture with compare mode
off; on OpenGL that needs a second sampler object and GL 3.3
(shadow_contact_hardening_supported()), Vulkan can always bind it.
Where the raw sampler isn't available, or the new Graphics.ShadowContactHardening
option is off, shadows_start_render() sets Shadow_penumbra_scale[cascade]
to -1 as a sentinel and pcssPenumbraRadius() (shadows.sdr) falls straight
back to the fixed radius, bit-identical to the pre-contact-hardening
behavior and skipping the extra texture reads.

When it is on, shadows_start_render() computes each cascade's penumbra
scale from its own frustum extents and the sun's tanθ; the shader turns
that plus the blocker search's average depth into a per-pixel radius,
clamped to [1 texel, the old fixed ceiling]. A blocker search that finds
nothing doesn't fall back to "no shadow" -- a sparse 8-tap search can
miss a thin occluder, so it instead runs the full filter at the hardest
(1-texel) radius, trading a touch of extra blur for not popping a real
shadow to nothing.

Drops RT_SHADOW_SUN_SIZE_CALIBRATION accordingly: that constant existed
only to fake a blocker-distance-driven penumbra on the shadow-mapped path
by pre-scaling the raytraced cone to match it, and the shadow-mapped path
now has a real blocker search of its own, so the raytraced cone goes back
to its physically correct size.

the-eandClaude Opus 5 5e745f7535 Add RTAO and unify raytraced/shadow-mapped shadow softness on sun angular size
Raytraced shadow penumbras needed a hand-authored $SunAngularSize: in
stars.tbl, which no shipped content sets -- so in practice nothing ever
got a penumbra, and the shadow-mapped path's $Shadow Smoothness Factor:
had no relation to it at all. Derive a size from the sun bitmap instead
and drive both methods from the same number.

g3_render_rect_screen_aligned_2d() sizes the sun quad so its rad is the
tangent of the half-angle it subtends, making tan(angular radius) equal
to 0.05 * the mission's +Scale: * the emitting disc's fraction of the
bitmap. That fraction is the area of the pixels at or above 90% of the
brightest one, converted to an equivalent radius. Across 90 sun bitmaps
from retail, the MediaVPs, Blue Planet and BtA it lands at a median of
0.261 (retail's chunkier art at 0.487), and the threshold acts as a
constant factor rather than a per-bitmap judgement call -- Spearman rho
0.96 between a 90% and a 50% cutoff.

Taken literally that yields suns 3.9-8.5x Sol's apparent diameter once
+Scale: is folded in (median 1.55, up to 5.0 in retail's own missions),
so the measurement is scaled by 0.25 and clamped to 1.5 degrees, putting
typical content near Sol. Derivation is the default: $SunAngularSize: 0
asks for hard shadows, an explicit value still wins, and missions can
also set +AngularSize: on an individual sun to override both, with FRED
and QtFRED UI (validation and fallback included) to author it. Bitmaps
that can't be read -- and the deliberately blank sun bitmaps mods ship
to get a light source with no visible disc -- fall back to hard shadows
rather than to the widest possible penumbra.

That angular size now sizes the raytraced penumbra cone directly
(traceShadowRayCone() in shadows.sdr), with sample count following the
same Shadow_quality tier that picks the shadow map's resolution (1 ray
at Low, up to 16 at Ultra) rather than being a separate setting. The
shadow-mapped path's tabled smoothness values were tuned by eye against
Sol-sized retail/MediaVPs art, so shadow_smoothness_scale() in
shadows.cpp scales them by the active sun's size relative to Sol,
clamped to what the shadow map can represent (shadow_clamp_smoothness()).
The two methods still disagree about occluder distance -- the raytracer
uses the real one, the shadow map's tabled values stand in for a blocker
distance pinned to the cascade's own extent -- so RT_SHADOW_SUN_SIZE_CALIBRATION
in shadows.sdr is a constant factor that makes a given $SunAngularSize:
read as roughly the same softness either way; it's the number to revisit
if the shadow map ever grows a real blocker search.

Also adds RTAO (raytraced ambient occlusion) sharing the same TLAS as
the shadow rays, with lighting-profile-driven radius/strength, and lab
controls for RT shadow quality (Low/High), the local light cap, RT
shadow samples, RTAO, and an angular-size override for comparing both
shadow methods against the same sun. All are safe to change live: they
only gate which lights are picked as shadow casters or scale existing
uniforms while filling the per-frame light data.

the-e eec4a9ce3e Refactor Vulkan descriptor set binding to reduce dynamic offset churn
- Consolidated dynamic descriptor offset logic into `DescriptorWriter::bindSets`, replacing repetitive `vkCmdBindDescriptorSets` patterns across Vulkan modules.
- Eliminated redundant descriptor binding operations for Material and PerDraw sets by centralizing logic in `bindSets`.
- Simplified descriptors by directly splitting offset changes from descriptor contents, avoiding unnecessary updates.
- Updated comments and documentation to align with the new approach while maintaining reference consistency.
- Applied optimizations across Vulkan modules (`VulkanPostProcessing`, `VulkanDescriptorManager`, etc.) to reduce per-draw overhead and improve readability.

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).

* 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.

Goober5000 e103eaeb45 add some XSTR entries (#5229)
Add XSTR entries for "or", "None", and "Nothing".

Note that there is already an XSTR entry for "none", but it does not have the right capitalization.

Note that "None" is localized in `textify_scancode` but not `textify_scancode_universal`.

This makes "Nothing" cargo use appropriate localization.

Fixes #5227.

EatThePath 452f554193 Crossing the specular rubicon (#4302)
* Applying directional brightness profile value, disconnected spec flags and made specular light always equal to diffuse light

* Switched over to new command line arguments

* Wire lab up to new lighting controls, and provide backwards-compatible defaults for emissive.

* cleanup unused new function

* make static some functions that can be static

* revise command-line and emissive handling

* handled specular sun depreciation and general removal of specular value handling

* Removed specular light color as a separate value in the uniform buffers.

* cleanup of leftover/post-rebase specular references

* further post-rebase repair of light flags command line and leftover specular

* move techroom/selection/breifing 'room' lights to a common function and
augment lighting setup for current rendering

* fixed some mishandling of lighting modifiers.

* Addressed code clarity and comments from review

Goober5000 f7dd1172c6 background bitmap fix, part 1
Adds the framework for loading and saving backgrounds with correct or incorrect angles.  Backgrounds in FSO will all have fixed angles internally, and newly created backgrounds in FRED will have fixed angles, but existing mission files will have incorrect angles.  The parser will determine whether the mission file contains fixed or unfixed angles and act accordingly.  (Actually fixing the angles will be done in part 2.)

Goober5000 e1f20be856 rename and adjust scope of Rotators_locked flag
The Rotators_locked flag was created specifically as a lab option that didn't affect animations or intrinsic rotations, so return it to that scope.  Also rename it to clarify that it applies to subsystems and to be future-proof for submodel translation.

Goober5000 575c050da4 reorganize submodel rotation
This moves submodel rotation out of the AI pipeline and into object movement.  With the exception of turret rotation (which remains in the AI code) this now allows all types of submodel rotation to happen in the same place.  Many associated functions have also been cleaned up.

In addition to making the code cleaner and clearer, this will make it much easier for intrinsic rotations and new animations to be applied to non-ship objects, such as weapons.
