port #181: retail viewer step subdivision (calc_num_steps 0x0050a0b0) - radius-anchored steps + remainder final step + viewer-exempt small-offset abort
The user's retail axiom (camera rock steady pressed into walls) vs our measured wall-press wander (~0.5mm/frame limit cycle, headless pin Issue181WallPressEquilibriumTests) sent us back to the decomp. Ghidra (clean, vs the BN x87 mush): retail VIEWERS subdivide the sweep into EXACTLY radius-length steps anchored at the start (offsetPerStep = offset*r/len, numSteps = floor(len/r)+1) with the final step recomputed mid-loop as the exact remainder (find_transitional_position 0x0050bdf0), and the negligible-offset abort is NON-viewer-only. Ours used ceil equal-slices for everything and aborted viewers too. Ported faithfully (pseudocode docs/research/2026-07-06-viewer-step-subdivision-pseudocode.md); non-viewer stepping already matched (TRANSITIONAL_PERCENT_OF_RADIUS=1.0). Measurement: the wall-press limit cycle is UNCHANGED by the port (537.8um avg; a bit-exact 12-frame cycle: ~130um/frame inward creep x11 then a 2.6mm snap). With adjust_to_plane + adjust_sphere_to_poly now also Ghidra-verified faithful, the residual mm cycle is likely retail-class plateau physics - invisible at retail's 60fps vsync, tear-interleaved into visible stripes at our ~1500fps unsynced. The decisive user test: VSync ON (Settings/F11). Fallback discriminator: cdb-trace retail's viewer at a wall press. Suites green (Core 2600 / App 733 / UI 425 / Net 385).

# `CTransition::calc_num_steps` + the viewer step loop — pseudocode (#181 equilibrium fix)
|
||||||
|
|
||||||
|
Source: Ghidra decompile (patchmem project, PDB-named) of `calc_num_steps`
|
||||||
|
(`0x0050a0b0`) and `find_transitional_position` (`0x0050bdf0`), read 2026-07-06
|
||||||
|
after the user's retail axiom ("retail camera is rock steady" pressed into
|
||||||
|
walls) contradicted acdream's measured wall-press wander (~0.5 mm/frame
|
||||||
|
forever, headless pin `Issue181WallPressEquilibriumTests`). The BN pseudo-C of
|
||||||
|
the same functions is x87 mush; Ghidra's is clean.

## The step loop's viewer handling — `find_transitional_position` 0x0050bdf0
|
||||||
|
|
||||||
|
```
|
||||||
|
for i in 0 .. numSteps-1:
|
||||||
|
# VIEWER LAST-STEP REMAINDER: the final step covers exactly what's left,
|
||||||
|
# so the swept path ends exactly at end_pos (no overshoot):
|
||||||
|
if (state & 4) and i == numSteps-1 and len > F_EPSILON:
|
||||||
|
offsetPerStep = offset * ((len - (numSteps-1)*r) / len)
|
||||||
|
|
||||||
|
global_offset = adjust_offset(offsetPerStep)
|
||||||
|
|
||||||
|
# The negligible-offset abort is NON-VIEWER-ONLY — a pressed camera keeps
|
||||||
|
# stepping through sub-epsilon adjusted offsets:
|
||||||
|
if (state & 4) == 0 and |global_offset|² < F_EPSILON²: break
|
||||||
|
|
||||||
|
... check_pos += global_offset; transitional_insert(3); validate ...
|
||||||
|
if collision_normal_valid and (state & 8): break # PathClipped first-hit stop
|
||||||
|
```
|
||||||
|
|
||||||
|
## Why this stabilizes the wall-press equilibrium (#181)
|
||||||
|
|
||||||
|
acdream's pre-fix stepping for ALL movers was `numSteps = ceil(len/r)` equal
|
||||||
|
slices. The camera's convergence loop (sought = lerp(viewer→desired) → sweep →
|
||||||
|
viewer) perturbs `len` by mm every frame:
|
||||||
|
|
||||||
|
- equal slices: every step boundary shifts with `len`, and at `len` near an
|
||||||
|
exact multiple of r (the measured press pose: 1.5 m = 5 × 0.3 m) the step
|
||||||
|
COUNT flaps ceil-wise, teleporting the colliding step's window ~5 cm — the
|
||||||
|
clip's committed point jumps mm-scale, and the loop orbits a limit cycle
|
||||||
|
instead of a fixed point (the measured ~0.5 mm/frame wander → the #181
|
||||||
|
flicker excitation);
|
||||||
|
- retail viewer grid: the first `floor(len/r)` steps are constant radius-length
|
||||||
|
increments anchored at the pivot — invariant under mm target drift — and only
|
||||||
|
the remainder step breathes. The colliding step's window is stable, the clip
|
||||||
|
result is stable, the loop reaches retail's fixed point ("rock steady").
|
||||||
|
|
||||||
|
Port sites: `Transition.FindTransitionalPosition` (TransitionTypes.cs) — the
|
||||||
|
subdivision block + the per-step loop (last-step remainder + the abort gate).
|
||||||
|
Non-viewer behavior unchanged (already matches).
