Frame Studio - Gaussian splats (PLY, SPZ v2-v4), PLY vertex colours, panorama skies - Copy, cut, paste and duplicate for objects, splats and world items - Walkable-area rebake moved off the UI thread; viewport one frame sooner; refresh-locked pacing (FS_PACE=timer for the old one) - Fixed: bundle thumbnail use-after-free crash, auto-save deleting environments, saves into scratch copies, edits lost on non-ASCII paths, unopenable manifests with inf/nan, bundle save data loss, opening a home marking it changed, gizmo NaN, long paths, many malformed-file crashes - Updater verifies sha256, journals the swap and never leaves the exe missing Frame Home - Seats turn you to face their way - Draw batching (Hand Tutorials up to ~20% less GPU time), cut-out EQUAL pass, late head-pose read before submit - Proper queue-family hand-over to the compositor layer; layer descriptor generations and seqlocked slots; structural SPIR-V check - Fixed: hangs/crashes on damaged .fenv files and shaders, render-pass validation error, sync hazard in the foveation smoothing pass, unverified update downloads, half-done installs Tests: tests_loco/env_share/spv_check wired into CMake (FRAME_TESTS) and CI.

// The canonicalize IDs pass is an optimization to improve compression of SPIR-V
|
|
// binary files via entropy reduction. It transforms SPIR-V to SPIR-V, remapping
|
|
// IDs. The resulting modules have an increased ID range (IDs are not as tightly
|
|
// packed around zero), but will compress better when multiple modules are
|
|
// compressed together, since the compressor's dictionary can find better cross
|
|
// module commonality. Remapping is accomplished via canonicalization. Thus,
|
|
// modules can be compressed one at a time with no loss of quality relative to
|
|
// operating on many modules at once.
|
|
|
|
// This pass should be run after most optimization passes except for
|
|
// --strip-debug because this pass will use OpName to canonicalize IDs. i.e. Run
|
|
// --strip-debug after this pass.
|
|
|
|
// This is a port of remap utility in glslang. There are great deal of magic
|
|
// numbers that are present throughout this code. The general goal is to replace
|
|
// the IDs with a hash value such that the distribution of IDs is deterministic
|
|
// and minimizes collisions. The magic numbers in the glslang version were
|
|
// chosen semi-arbitrarily and have been preserved in this port in order to
|
|
// maintain backward compatibility.
