From 3480945b5afe2320d76bad0bbd1c04b9c2b06666 Mon Sep 17 00:00:00 2001 From: minsung Date: Tue, 4 Aug 2026 14:08:59 +0900 Subject: [PATCH] perf(viewer2d): toggle layers by visibility instead of reloading the drawing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit setHiddenLayers() called load(result, {keepView:true}), so every layer on/off re-parsed and re-tessellated the whole drawing — arc sampling, hatch triangulation, complex linetypes and the Slug text batch all rebuilt from scratch. On an 18 MB DWG a single eye-icon click took 5 s+. Build every layer once, then switch geometry on and off: - Merged LineSegments buffers get an index buffer plus a per-segment layer id (_registerIndexed). A toggle rewrites the index and setDrawRange; positions, colors and lineDistances are untouched, so draw order, dash phase and the selection-highlight offsets in meta.colStart stay valid. - Per-entity meshes (hatch fills, SOLID quads, arrowheads, OLE images, sprites) are tagged by layer via _addObj and toggled with .visible. - Slug text builds one merged mesh per CAD layer instead of one per draw order, so text hides with a visible flag. The shader source is identical across batches, so three still shares one WebGLProgram. - Hidden geometry stays in the pick buffers, so _onClick now skips it via the _metaHidden mask. - Fit keeps framing only what is drawn: per-layer Box3 + fit samples are recorded at build and unioned over the visible layers. - getLayerInfo() caches the O(entities) name/color/count pass per load; only the visible flag is recomputed. Layer panel: one delegated click listener instead of re-binding a handler per row, and a toggle patches the affected row's opacity/icon in place rather than regenerating the whole list's innerHTML. Trade-off: hidden layers are now built and kept in memory, so loading a file with layers already off costs what a full load costs. Rebuilds dist2.
