- pointer events with pointer capture: a drag only starts on the canvas, continues outside it and ends on release; deltas from clientX/Y instead of the non-standard layerX (a drag entering from outside made the camera NaN) - without WebGL 2 show a message in the page instead of an alert with raw HTML, and refuse to load files - normal fallback for zero-area polygons used vec3.create(args), which ignores its arguments and returned a zero normal - canvas resolution in device pixels (CSS size * devicePixelRatio), mouse movement stays in CSS pixels - index.html: charset, viewport and lang Co-Authored-By:

Loading - parse into fixed-size per-LOD blocks and upload them to the GPU while reading, so memory stays flat for multi-GB files (3.4 GB 3D-DLM loads with a JS heap below 90 MB) and the model is shown during loading - load the single .gml (or .xml) inside a zip archive, decompressed as a stream, including ZIP64 - reject 7z/RAR/gzip and other non-XML input at once with a clear message, and enable the sax buffer limit that unterminated "<!" in binary data used to bypass until the tab ran out of memory - decode UTF-8 across chunk borders, cancel a running load when a new file is chosen, report load errors Geometry - split coordinates on any whitespace (indented posList, one pos per line) - subtract the origin in double precision before float32 conversion - handle PolygonPatch, Rectangle and Triangle - tag geometry with its LOD; setLodVisible() prepares LOD switches - light brown for land use and relief, nested colours restore the parent View - bind shader attribute locations, check compile/link errors, free GPU buffers of the previous file - infinite far plane with a near plane following the camera distance, starting distance fitted to the model without a 10 km cap - minimum zoom step and distance, pan speed proportional to the distance Tests: npm test (Node 22+), 73 tests Co-Authored-By:
