2b41912c4d'what an expensive mistake this turned to to be' (was curious and revived my mistake of a .5K rig from a couple of years ago to toss the CPU=>GPU serialization issue at it just for it to shuffle some lines after 5M tokens)ecker2026-08-19 15:44:13 -0500

a43b1567b3rabbithole of swapping VXGI to SVOGI (currently enabled arbitrary regions to voxelize into (mostly working)), repaired shadowmaps (kind of flickers from depth precision when moving), to-do: fix annoying race issue when GPU is under load that is not fixed with N-buffered attachments, but is fixed with vkDeviceWaitIdle (although this is a horribad bandaid fix)ecker2026-08-15 23:36:26 -0500

956b0ddb4afinal fixes (refit/decide is flat aware, can fully clear unflat bounds/nodes when flattened, some timing issue with creating/initializing/updating the physics state), dreamcast still stutters on streaming in data though......ecker2026-08-09 13:13:48 -0500
d078784088fixed footsteps returning wrong sound (due to it assuming the view ID was a triangle ID), overhauled flattened BVHs by shrinking node size and quantizing AABBS to reduce memory footprint, fixed BVHs to clear the unflattened node/bounds when flattened (for meshes, broadphase BVHs need to be updated to use the flattened versions)ecker2026-08-09 11:35:04 -0500
1324cf7e42properly fixed this streamed-in BVH nightmare (to-do: fix the footsteps because it's passing in a local triangle ID instead of a global triangle ID like it expected before)ecker2026-08-08 22:55:20 -0500
992556b054more fixes (to-do: fix BVH serialization/deserialization since I'm very sure it's wrong, but everything else should be plumbed right)ecker2026-08-08 20:54:32 -0500
24d1d63516actually fix BVH building, overhauled BVH building to (theoretically) allow for nodes to be disabled so the BVH is loaded once and unloaded mesh regions are deactivated, build mesh BVHs when saving graph to disk and load them (to-do: actually fix it, since the writer might be broken)ecker2026-08-08 16:09:13 -0500

fed6db2d17more overkill optimizations (dedicated uf::thread implementation for KOS, replaced std::istream in VFS, mesh code cleanup, probably fixed std::swap maybe naively copying), dramatically sped up mesh streaming/processing, but still a small noticeable stutter on the dreamcastecker2026-08-07 21:08:58 -0500
25ee978a8dfixed bug in texconv, dreamcast settings adjustments (namely shrinking the threshold for reading the entire file vs streaming it in because for some reason I thought 2MB wasn't an issue)ecker2026-08-07 10:30:26 -0500
e3ae6d6b85mesh streaming works with interleaved meshes, overhauled mesh streaming to work asynchronously (ironically only x86_64 OpenGL works well with it), reverted dtex conversion to 32x32 because any larger size doesn't actually workecker2026-08-06 20:45:41 -0500
d758cf6db9fixed some weird memory leak with keymap import/merge, validated allocator settings, some other things (mds-mcdonalds can now theoretically load on a real dreamcast) (to-do: asynchronous mesh loading since it stutters on streaming new mesh data)ecker2026-08-05 20:18:21 -0500
f4fdf5208ffixed emitted audio crashing if not-existant, fixed GLdc non-compressed texture loading, bin lightmaps to partitions for NewDark MIS and Valve BSP loaders (NewDark doesn't group by portal-cell), validated that game scene does load on dreamcast (even though mds-mcdonalds clocks at 23MiB at runtime with gutting everything......)ecker2026-08-04 20:40:56 -0500

9597916568fixed simd normalize because i guess you needed to check for dot > eps2, actually enabled use of custom allocator for uf::stl containers, updated nlohmann/json wrapper to use supplied types (should fully remove the need to glue on float64_t to it for dreamcast, even though either -m4/-m4-single fixed that last i checked), fixed weird issue with debug draw having frame % 3 draw the wireframe without a transformation matrix presumably because the camera viewport was [4] instead of [6] (even-even though it fixed itself when i only set the specialization constant for debug text only), mostly corrected source-engine physics state even though it should probably get defined in the bsp loader or somethingecker2026-07-23 21:45:57 -0500
