茂之钳	ebc47a25c9	fix: remove stray namespace close in test_iges_import	2026-07-24 08:16:51 +00:00
茂之钳	6cfd186780	feat(brep): S13-A — IGES import support ... Implement IGES (Initial Graphics Exchange Specification) file reader that converts IGES entities to B-Rep models. Key features: - 80-character fixed-width card image parser (S/G/D/P/T sections) - Directory Entry parsing with all 18 DE fields per entity - Parameter Data parsing with DE pointer tracking - D exponent notation support (e.g., 1.5D+2 = 150) Supported IGES entity types: Curve entities (→ NurbsCurve): Type 100 - Circular Arc (rational degree-2) Type 102 - Composite Curve Type 104 - Conic Arc (ellipse/hyperbola/parabola) Type 106 - Copious Data (polyline) Type 110 - Line (degree-1) Type 126 - Rational B-Spline Curve Surface entities (→ NurbsSurface): Type 108 - Plane Type 114 - Parametric Spline Surface Type 118 - Ruled Surface Type 120 - Surface of Revolution Type 122 - Tabulated Cylinder (extrude) Type 128 - Rational B-Spline Surface Type 140 - Offset Surface Type 192 - Right Circular Cylindrical Surface Type 194 - Right Circular Conical Surface Type 196 - Spherical Surface Type 198 - Toroidal Surface Topology entities (→ BrepModel): Type 186 - Manifold Solid B-Rep Object Type 502 - Vertex Type 504 - Edge Type 508 - Loop Type 510 - Face Type 514 - Shell Tests cover: line, arc, cylinder, sphere, cone, torus, plane, B-spline curve/surface, ruled surface, revolution surface, tabulated cylinder, copious data polyline, manifold solid B-Rep, D exponent notation, empty/truncated file handling, and file errors.	2026-07-24 07:37:03 +00:00
茂之钳	4f75bb8b07	feat(brep): S13-B IGES export + format utilities ... Add IGES v5.3 export for B-Rep models with: - Entity mapping: Point(116), Line(110), Circular Arc(100), B-Spline Curve(126), Plane(108), B-Spline Surface(128), Vertex(502), Edge(504), Loop(508), Face(510), Shell(514), Manifold Solid B-Rep(186) - Auto-detection of circular arcs (degree-2 NURBS with isosceles control triangle) and planes (1x1 degree surfaces) - Fixed 80-column IGES format with S/G/D/P/T sections - Header-only format_utils.h for IGES/STEP number formatting New files: - include/vde/foundation/format_utils.h - include/vde/brep/iges_export.h - src/brep/iges_export.cpp - tests/brep/test_iges_export.cpp	2026-07-24 07:34:27 +00:00
