Triangulation with refinement

To proceed with triangulation using mesh refinement, set RefineMesh to true and specify the required RefinementThresholds:

using var inputPositions = new NativeArray<double2>(..., Allocator.Persistent); using var triangulator = new Triangulator(Allocator.Persistent) { Input = { Positions = inputPositions }, Settings = { RefineMesh = true, RefinementThresholds = { Area = 1f, Angle = math.radians(20f) }, } }; triangulator.Run(); var triangles = triangulator.Output.Triangles; var positions = triangulator.Output.Positions; 

The refinement process is controlled by two threshold parameters:

• Area: denoted as \(C_\triangle\)
• Angle: denoted as \(C_\theta\)

These parameters allow fine-tuning of the refinement results based on specific criteria. Below, you can observe a set of results obtained by applying the refinement process to input data from Lake Superior (open the image in a new tab to see the details).

Note

Refinement is available for both constrained and non-constrained triangulation.
