MarchingCubes

<MarchingCubes /> is a wrapper around THREE's Marching Cubes.

It includes 3 components:

• <MarchingCubes /> – container element for <MarchingCube />s and <MarchingPlane />s
• <MarchingCube /> - an individual metaball
• <MarchingPlane /> – optional bounding plane that interacts with the metaballs

Usage

<script setup lang="ts">
import { MarchingCube, MarchingCubes, MarchingPlane, OrbitControls } from '@tresjs/cientos'
import { TresCanvas } from '@tresjs/core'
import { NoToneMapping, Vector3 } from 'three'

const rand = () => (Math.random() - 0.5) * 1.25
const positions = Array.from({ length: 40 }, () => new Vector3(rand(), rand(), rand()))
</script>

<template>
  <TresCanvas clear-color="#222" :tone-mapping="NoToneMapping">
    <TresPerspectiveCamera />
    <OrbitControls />

    <MarchingCubes :resolution="40" :max-poly-count="40000">
      <MarchingPlane plane-type="y" />
      <MarchingCube
        v-for="position, i of positions"
        :key="i"
        :position="position"
      />
      <TresMeshPhongMaterial specular="#111111" :shininess="30" color="#049ef4" :reflectivity="1" />
    </MarchingCubes>

    <TresAxesHelper />
    <TresDirectionalLight color="#ffffff" :intensity="3" :position="[0, 200, 0]" />
    <TresDirectionalLight color="#ffffff" :intensity="3" :position="[100, 200, 100]" />
  </TresCanvas>

Props

Prop	Description	Default
resolution	Resolution of the marching cube field. Higher resolution produces smoother meshes at the cost of performance and memory.	28
maxPolyCount	Maximum number of polygons to generate.	10000
enableUvs	Whether UVs are enabled.	false
enableColors	Whether vertex colors are enabled.	false

<MarchingCube /> Props

Prop	Description	Default
strength	How strongly this cube affects the marching cube field.	0.5
subtract	How quickly strength moves to 0 over distance.	12

<MarchingPlane /> Props

Prop	Description	Default
planeType	Which axis the plane appears on. 'x' | 'y' | 'z'	'x'
strength	How strongly this plane affects the marching cube field.	0.5
subtract	How quickly strength moves to 0 over distance.	12
