How to Create Geometry inside Swift Applications?

// create some geometry using Euclid
        let start = CFAbsoluteTimeGetCurrent()
        let cube = Mesh.cube(size: 0.8, material: UIColor.red)
        let sphere = Mesh.sphere(slices: 120, material: UIColor.blue)
        let mesh = cube.subtract(sphere).makeWatertight()

        print("Time:", CFAbsoluteTimeGetCurrent() - start)
        print("Polygons:", mesh.polygons.count)
        print("Triangles:", mesh.triangulate().polygons.count)
        print("Watertight:", mesh.isWatertight)

Create & Manage Meshes inside Swift Apps

The open source Euclid library has included powerful functionality for creating, rendering and displaying 3D shapes created with meshes inside Swift applications. The library supports several important features for working with meshes such as creating ,meshes from other meshes, creating meshes from polygons, creating meshes from paths, creating meshes from vertices or points or line-segments, creating meshes from text, exporting meshes, accessing mesh properties, comparing meshes, transforming meshes, merging meshes, splitting meshes and so on.

How to Create a New Meshes & Display It via Swift API?

import Euclid

struct Mesh {
    var vertices: [Vector3]
    var faces: [Face]

// Create a new instance of the Mesh struct and initialize its properties.

var mesh = Mesh(vertices: [
    Vector3(0, 0, 0),
    Vector3(1, 0, 0),
    Vector3(0, 1, 0)
], faces: [
    Face(a: 0, b: 1, c: 2)

// To visualize the mesh, you can use a rendering framework like SceneKit or Metal.

import SceneKit

let scene = SCNScene()

let geometry = SCNGeometry(sources: [
    SCNGeometrySource(vertices: mesh.vertices.map { SCNVector3($0.x, $0.y, $0.z) })
], elements: [
    SCNGeometryElement(indices: mesh.faces.flatMap { [$0.a, $0.b, $0.c] }, primitiveType: .triangles)

let node = SCNNode(geometry: geometry)

let sceneView = SCNView(frame: CGRect(x: 0, y: 0, width: 500, height: 500))
sceneView.scene = scene

// Add the scene view to your view hierarchy or present it as desired.
