DV8.SimplifyLines 1.0.4

DV8.SimplifyLines

An updated fork/rewrite of simplify.net (https://github.com/imshz/simplify-net), which again is a fork/rewrite of simplify-js (https://github.com/mourner/simplify-js)

Installation / Nuget

See https://www.nuget.org/packages/DV8.SimplifyLines/

Highlights

• Simplify lines using the Douglas-Peucker algorithm or Radial-Distance algorithm
• Simple syntax/usage, see below
• Configurable resolution
• Uses standard dotnet data structures (Vector3)
• Dependency free

Usage

See SimplifyShapesTests.cs for full code and more examples

        var points = CreateHighResolutionSquare();
        AreEqual(4 * 1001, points.Count);

        var simplified = SimplifyUtility.SimplifyArray(points.ToArray());
        // Note: 5 points, not 4, because we need to close the square
        AreEqual(5, simplified.Count); 

Example SVGs

The following SVGs are generated using the SimplifyShapesTests.cs

Square (~10000 points)

Simplified square (5 points)

Cicle (~6284 points)

Simplified circle (~33 points)

Very simplified circle (~9 points)

Changes from simplify.net:

• updated .Net version (now supports dotnet 6+)
• fixed spelling errors
• updated code to modern standard
• changed namespace to DV8.SimplifyLines to enable NuGet package
• changed data structure to Vector3, to enable hardware acceleration
