From deeb8ac54f71d4322a778336db9a7aec411c23ce Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Mon, 28 Sep 2026 16:44:51 -0300 Subject: G1: Lift, soft elevation shadows (off by default) `Lift` (a GUI toggle, capability lift) lifts the focused pane on a critically damped spring (animation.Spring: closed form, about 240 ms to settle, velocity kept across retargets, settled = no frames) and floats notices. The core puts the lift on the regions (Region.lift, on the wire); the GUI casts from it: a soft shadow is decor, an erf rectangle on one quad grown by 3 sigma (decor.frag, flag 0x10000000), in the quad's own space so a track's transform carries it; darken-only, the caster's rect left alone, alpha pre-warped for linear light and IGN-dithered. Cast last in its group, so a neighbour's rails and rules darken with its text; a notice's before its rule. Strength is capped per theme so text over the darkest shadow keeps min(its contrast, 4.5) (test over the native themes). Opt-in until the focus lift/dim default is decided. Feel review material: docs/effects.md. Test-mode PARDES_TEST_SERIES keeps every captured frame. Shared files touched: pardes.zig (two fields, one nextWake line), detached/wire.zig (lift on the region), config.zig, builtins.zig (capability), gui.zig. Not touched: Messages.zig, mouse.zig, tty, host_io. --- docs/effects.md | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) create mode 100644 docs/effects.md (limited to 'docs/effects.md') diff --git a/docs/effects.md b/docs/effects.md new file mode 100644 index 00000000..44f3e949 --- /dev/null +++ b/docs/effects.md @@ -0,0 +1,18 @@ +# Effects: feel reviews + +Each effect of docs/render-pipeline.md §9 lands behind its own switch, off, +and is kept only after a feel review (§8.4): a frame series on the virtual +clock, a recording, and a verdict — keep, polish or drop — with one line of +why.
