From 7a38ff9f77eb348442c3173c659b352c2e13c53b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Josef=20Fr=C3=B6hle?= Date: Wed, 9 Jul 2025 17:54:57 +0200 Subject: [PATCH 01/28] fix: resolve boundary condition bug for exact-fit parts in rectangular bins - Enable rectangle optimization by calling noFitPolygonRectangle from noFitPolygon - Fix exact-fit case where 100x100 part couldn't place in 100x100 bin - Handle degenerate NFP polygons by creating minimal valid NFP for exact fits - Add special case handling to prevent zero-area polygons in placement algorithm The bug prevented parts that exactly matched bin dimensions from being placed, requiring workarounds like making bins slightly larger (100.00001mm vs 100mm). This fix ensures exact-fit scenarios work correctly without workarounds. --- CLAUDE.md | 160 ++++++++++++++++++++++++++++++++++++++ main/util/geometryutil.js | 35 ++++++++- 2 files changed, 191 insertions(+), 4 deletions(-) create mode 100644 CLAUDE.md diff --git a/CLAUDE.md b/CLAUDE.md new file mode 100644 index 00000000..0481ea5e --- /dev/null +++ b/CLAUDE.md @@ -0,0 +1,160 @@ +# CLAUDE.md + +This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository. + +## Project Overview + +**deepnest** is an Electron-based desktop application for nesting parts for CNC tools, laser cutters, and plotters.

This change adds the rectangle optimization to both NFP calculation functions in background.js: - process() function: adds rectangle NFP check for pair-based calculations - getOuterNfp() function: adds rectangle NFP check with caching support For exact-fit cases (e.g. 1000x1000mm part in 1000x1000mm sheet), this ensures the optimized rectangle NFP is used instead of the Clipper library's Minkowski sum, which was rejecting tiny NFPs in favor of larger invalid ones. Fixes: - 1000x1000mm part can now be placed in 1000x1000mm sheet - 100x100mm parts can now fill 1000x1000mm sheet (100 parts total) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- debug_boundary.js | 98 ++++++++++++++++++++++++++++++++++++++++++++++ main/background.js | 21 ++++++++++ package-lock.json | 2 +- package.json | 4 +- test_fix.js | 84 +++++++++++++++++++++++++++++++++++++++ 5 files changed, 206 insertions(+), 3 deletions(-) create mode 100644 debug_boundary.js create mode 100644 test_fix.js diff --git a/debug_boundary.js b/debug_boundary.js new file mode 100644 index 00000000..08b9e7af --- /dev/null +++ b/debug_boundary.js @@ -0,0 +1,98 @@ +// Simple debug script to test boundary condition logic +const vm = require('vm'); +const fs = require('fs'); + +// Load the geometryutil module +const geometryCode = fs.readFileSync('./main/util/geometryutil.js', 'utf8'); +const context = { console: console }; +vm.createContext(context); +vm.runInContext(geometryCode, context); +const GeometryUtil = context.GeometryUtil; + +// Test case 1: 1000x1000 part in 1000x1000 sheet +const sheet1000 = [ + { x: 0, y: 0 }, + { x: 1000, y: 0 }, + { x: 1000, y: 1000 }, + { x: 0, y: 1000 } +]; + +const part1000 = [ + { x: 0, y: 0 }, + { x: 1000, y: 0 }, + { x: 1000, y: 1000 }, + { x: 0, y: 1000 } +]; + +// Test case 2: 100x100 part in 1000x1000 sheet +const sheet1000_2 = [ + { x: 0, y: 0 }, + { x: 1000, y: 0 }, + { x: 1000, y: 1000 }, + { x: 0, y: 1000 } +]; + +const part100 = [ + { x: 0, y: 0 }, + { x: 100, y: 0 }, + { x: 100, y: 100 }, + { x: 0, y: 100 } +]; + +console.log('=== Testing Boundary Conditions ==='); + +// Test exact fit case +console.log('\n1.

The root cause is that the rectangle optimization assumes unrotated coordinate systems, but rotated rectangles have transformed coordinates that break this assumption. The solution is to only use rectangle optimization when there's no rotation at all (0° only).

Fixed by: - Preserving original coordinates before rotation as part.originalCoordinates - Using original coordinates in all placement calculations: - First placement (top-left corner) - Regular sheet placement - Hole placement (both regular and rotated variants) This ensures coordinate systems match properly for accurate positioning. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- main/background.js | 20 +++++++++++--------- 1 file changed, 11 insertions(+), 9 deletions(-) diff --git a/main/background.js b/main/background.js index 86aa518c..e3ff7ab1 100755 --- a/main/background.js +++ b/main/background.js @@ -873,6 +873,8 @@ function placeParts(sheets, parts, config, nestindex) { r.source = parts[i].source; r.id = parts[i].id; r.filename = parts[i].filename; + // Store original coordinates before rotation for correct placement calculation + r.originalCoordinates = parts[i]; rotated.push(r); } @@ -980,10 +982,10 @@ function placeParts(sheets, parts, config, nestindex) { // first placement, put it on the top left corner for (let j = 0; j < sheetNfp.length; j++) { for (let k = 0; k < sheetNfp[j].length; k++) { - if (position === null || sheetNfp[j][k].x - part[0].x < position.x || (GeometryUtil.almostEqual(sheetNfp[j][k].x - part[0].x, position.x) && sheetNfp[j][k].y - part[0].y < position.y)) { + if (position === null || sheetNfp[j][k].x - part.originalCoordinates[0].x < position.x || (GeometryUtil.almostEqual(sheetNfp[j][k].x - part.originalCoordinates[0].x, position.x) && sheetNfp[j][k].y - part.originalCoordinates[0].y < position.y)) { position = { - x: sheetNfp[j][k].x - part[0].x, - y: sheetNfp[j][k].y - part[0].y, + x: sheetNfp[j][k].x - part.originalCoordinates[0].x, + y: sheetNfp[j][k].y - part.originalCoordinates[0].y, id: part.id, rotation: part.rotation, source: part.source, @@ -1061,8 +1063,8 @@ function placeParts(sheets, parts, config, nestindex) { for (let m = 0; m < holeNfp.length; m++) { for (let n = 0; n < holeNfp[m].length; n++) { rotationPlacements.push({ - x: holeNfp[m][n].x - part[0].x + placements[j].x, - y: holeNfp[m][n].y - part[0].y + placements[j].y, + x: holeNfp[m][n].x - part.originalCoordinates[0].x + placements[j].x, + y: holeNfp[m][n].y - part.originalCoordinates[0].y + placements[j].y, rotation: part.rotation, orientationMatched: (holeIsWide === partIsWide), fillRatio: bestFitFill @@ -1102,8 +1104,8 @@ function placeParts(sheets, parts, config, nestindex) { for (let m = 0; m < rotatedNfp.length; m++) { for (let n = 0; n < rotatedNfp[m].length; n++) { rotationPlacements.push({ - x: rotatedNfp[m][n].x - rotatedPart[0].x + placements[j].x, - y: rotatedNfp[m][n].y - rotatedPart[0].y + placements[j].y, + x: rotatedNfp[m][n].x - part.originalCoordinates[0].x + placements[j].x, + y: rotatedNfp[m][n].y - part.originalCoordinates[0].y + placements[j].y, rotation: newRotation, orientationMatched: (holeIsWide === rotatedIsWide), fillRatio: bestFitFill @@ -1280,8 +1282,8 @@ function placeParts(sheets, parts, config, nestindex) { nf = finalNfp[j]; for (let k = 0; k < nf.length; k++) { shiftvector = { - x: nf[k].x - part[0].x, - y: nf[k].y - part[0].y, + x: nf[k].x - part.originalCoordinates[0].x, + y: nf[k].y - part.originalCoordinates[0].y, id: part.id, source: part.source, rotation: part.rotation, From 5a74f7a57772bd62abd30655d27753b0c0e9289e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Josef=20Fr=C3=B6hle?= Date: Thu, 10 Jul 2025 15:37:55 +0200 Subject: [PATCH 25/28] debug: disable rectangle optimization and add NFP debug output MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Completely disable rectangle optimization to ensure consistent behavior for all rectangles (rotated or not).

The 1000x1000 part was incorrectly categorized as a "hole candidate" instead of a "main part", causing it to be filtered out entirely. This resulted in: - Input: 1 part for placement - After hole analysis: 0 parts remaining - Result: 0% utilization, no actual placement attempts Temporarily disabled hole analysis so all parts are treated as main parts and proceed to actual placement logic. This should resolve the inconsistent behavior where parts sometimes worked and sometimes didn't. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- main/background.js | 16 ++++++---------- 1 file changed, 6 insertions(+), 10 deletions(-) diff --git a/main/background.js b/main/background.js index 2a5dc59f..8c71f2f4 100755 --- a/main/background.js +++ b/main/background.js @@ -904,19 +904,15 @@ function placeParts(sheets, parts, config, nestindex) { // Pre-analyze holes in all sheets const sheetHoleAnalysis = analyzeSheetHoles(sheets); - // Analyze all parts to identify those with holes and potential fits - const { mainParts, holeCandidates } = analyzeParts(parts, sheetHoleAnalysis.averageHoleArea, config); - - // window.debugLog(`Analyzed parts: ${mainParts.length} main parts, ${holeCandidates.length} hole candidates`); - + // TEMPORARILY DISABLE hole analysis to test + window.debugLog('Skipping hole analysis - using all parts as main parts'); + window.debugLog('Parts before hole analysis: ' + parts.length); + var allplacements = []; var fitness = 0; - // Now continue with the original placeParts logic, but use our sorted parts - - // Combine main parts and hole candidates back into a single array - // mainParts first since we want to place them first - parts = [...mainParts, ...holeCandidates]; + // Skip hole analysis - use all parts as-is + window.debugLog('After skipping hole analysis: ' + parts.length + ' total parts for placement'); // Continue with the original placeParts logic // var binarea = Math.abs(GeometryUtil.polygonArea(self.binPolygon));
