What is a unique method for creating a wireframe that replicates the structure of a square grid without using interconnected nodes

Currently, I am in the process of designing the wire frame styles for human body OBJs and my goal is to achieve a wire frame similar to the image below. In the following lines, you will find the code snippets that illustrate how I create the wire frame along with images depicting its current appearance and the expected final look.

// Using 'child' as the type THREE.Mesh representing the human body's OBJ.
const geo = new THREE.WireframeGeometry(child.geometry)
const mat = new THREE.LineBasicMaterial({color: 0xffffff})
const wireframe = new THREE.LineSegments(geo, mat)
child.add(wireframe)

Answer №1

import * as THREE from 'three'

function generateCustomTexture() {
  const width = 200
  const height = 200
  const color = new THREE.Color(0x05cfe8)
  const size = width * height
  const data = new Uint8Array(3 * size)

  const r = Math.floor(color.r * 255)
  const g = Math.floor(color.g * 255)
  const b = Math.floor(color.b * 255)

  for (let i = 0; i < size; i++) {
    const stride = i * 3
    // Changing color patterns based on a specific condition
    if ((i / 3) % 4 === 0) {
      data[stride] = r
      data[stride + 1] = g
      data[stride + 2] = b
    } else {
      data[stride] = 255
      data[stride + 1] = 255
      data[stride + 2] = 255
    }
  }

  // Using buffer to create a custom DataTexture

  const texture = new THREE.DataTexture(data, width, height, THREE.RGBFormat)
  return texture
}
