- SoAHeap: hole method for bubbleUp/sinkDown (half the typed-array
writes per heap level vs the old swap approach).
- Seed dedup: Number keys instead of BigInt when vertex count < 94M
(10-50x faster per key). BigInt fallback for extreme meshes.
- addCreaseQuadrics: encode face pairs as negative numbers instead
of allocating small arrays per edge.
- Guard 3 (checkFlipped): single branch for corner index instead of
9 ternary operations per face.
- Yield interval kept at 4096 with setTimeout(0) for reliable UI updates.
- Render loop now only calls renderer.render() when the scene actually
changed (needsRender flag + requestRender export). Idle GPU usage
drops to near zero.
- Disabled shadow map (no receiver in scene, wasted a full render pass).
- Reuse overlay materials instead of creating new ones every paint frame.
- Dispose CanvasTexture in getEffectiveMapEntry (VRAM leak on every
slider change).
- Dispose axes/dimension geometry on model reload.
- Reuse Vector3/Quaternion temp objects in pointer/touch/wheel handlers
instead of allocating ~10 objects per mouse event.
- RAF-batch mousemove for hover/cursor, keep paint events immediate.
- Reuse faceMask buffer attribute when size matches.
- Cache getEffectiveMapEntry result (skip canvas tiling+blur when
texture and smoothing haven't changed).
- addSmoothNormals: same dedup+flat-array approach as displacement.
Displacement, subdivision and exclusion all used template-string keys
for vertex dedup and edge lookup maps. Replaced with a single numeric
dedup pass + flat typed arrays (Float64Array / Uint8Array), cutting
displacement time by ~2.5x and subdivision by ~2.4x on a 68k tri STL.
- displacement.js: vertex dedup → flat arrays for smooth normals,
zone areas, masked fractions, displacement cache, excluded set
- subdivision.js: numeric edge keys (a*maxV+b) instead of template strings
- exclusion.js: numeric edge keys, BFS queue.shift() → index pointer,
adjacency Map → Array, TypedArray.set() for overlay copy
- mapping.js: Math.pow(x,4) → x²·x², cos/sin cached per computeUV call,
applyTransform signature changed to accept precomputed cos/sin
- Added stripes.png and stripes_02.png with metadata from Adobe Photoshop.
- Included two new woodgrain textures (woodgrain_02.jpg and woodgrain_03.jpg) for enhanced visual variety.
- Renamed "Surface Mask" section to "Mask Angles" for clarity in index.html.
- Updated translation keys and tooltips to reflect the new terminology in i18n.js.
- Removed the erase toggle button from the exclusion panel and implemented Shift key functionality to toggle erase mode in main.js.
- Adjusted brush radius handling to improve user experience and updated related UI elements in index.html.
- Enhanced the subdivision process to track original face IDs for better masking accuracy in subdivision.js.
- Added CSS styles for new UI elements and improved layout in style.css.
