Free Swift Library for 3D Geometry Operations

Open Source Swift 3D library for Handling 3D Geometry Operations, such as Calculating Distances, Intersections, Orientations, & Transformations and Manage 3D Meshes.

What is Euclid Library?

Euclid is a free 3D geometry library that developers and mathematicians find incredibly useful. Its wide range of functions, easy-to-use design, and detailed guides have changed how people work with 3D geometry. Euclid offers many mathematical tools and methods that help developers solve geometric issues quickly and effectively. Euclid is a powerful tool made for 3D geometry tasks that works well across different platforms. It comes packed with various functions and structures to help you handle tricky geometric calculations like measuring distances, figuring out intersections, orientations, and making transformations.

Euclid is all about being simple, efficient, and adaptable. That’s why it’s a hit with coders, scholars, and teachers who appreciate how user-friendly and versatile it is. The Euclid 3D Geometry Library has made a big difference in different areas like computer graphics, robotics, virtual reality, and scientific simulations. Euclid offers a reliable and effective set of tools that speeds up the creation of 3D applications. This allows software developers to concentrate on tackling more advanced problems instead of starting from scratch. Euclid’s wide range of features, easy-to-use design, and supportive community have made handling complex geometric tasks simpler saving time and effort for programmers and researchers.

Comprehensive Geometry Operations via Swift

The open source Euclid library has revolutionized the way 3D geometry is approached and implemented in various Swift applications. It has provided an extensive set of functions that cover all major 3D geometric operations, such as point manipulation, vector algebra, line intersection, plane calculations, and mesh processing. These operations form the building blocks for various applications, such as computer graphics, robotics, physics simulations, and CAD/CAM software.

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)
scene.rootNode.addChildNode(node)

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.
