Plotly is a free and open-source graphing library for JavaScript. We recommend you read our Getting Started guide for the latest installation or upgrade instructions, then move on to our Plotly Fundamentals tutorials or dive straight in to some Basic Charts tutorials.

Simple 3D Mesh Plot

// Generating random data..
a=[]; b=[]; c=[];
for(i=0;i<50;i++)
  {
    var a_ = Math.random(); 
    a.push(a_);
    
    var b_ = Math.random(); 
    b.push(b_);
    
    var c_ = Math.random(); 
    c.push(c_);
  }
// Plotting the mesh
var data=[
    {
      opacity:0.8,
      color:'rgb(300,100,200)',
      type: 'mesh3d',
      x: a,
      y: b,
      z: c,
    }
];
Plotly.newPlot('myDiv', data);

3D Mesh Plot with Alphahull

// Generating random data..
a=[]; b=[]; c=[];
for(i=0;i<50;i++)
  {
  var a_ = Math.random(); 
   a.push(a_);
  
  var b_ = Math.random(); 
   b.push(b_);
  
  var c_ = Math.random(); 
   c.push(c_);
  }
// Plotting the mesh
var data=[
  {
    alphahull:5,
    opacity:0.8,
    color:'rgb(200,100,300)',
    type: 'mesh3d',
    x: a,
    y: b,
    z: c,
  }
];
Plotly.newPlot('myDiv', data);

3D Mesh Tetrahedron

var data = [{
    type: "mesh3d",
    x: [0, 1, 2, 0],
    y: [0, 0, 1, 2],
    z: [0, 2, 0, 1],
    i: [0, 0, 0, 1],
    j: [1, 2, 3, 2],
    k: [2, 3, 1, 3],
    intensity: [0, 0.33, 0.66, 1],
    colorscale: [
      [0, 'rgb(255, 0, 0)'],
      [0.5, 'rgb(0, 255, 0)'],
      [1, 'rgb(0, 0, 255)']
    ]
  }
];

Plotly.newPlot('myDiv', data, {});

3D Mesh Cube

var intensity = [0, 0.14285714285714285, 0.2857142857142857, 0.42857142857142855, 0.5714285714285714, 0.7142857142857143, 0.8571428571428571, 1];

var data = [{
    type: "mesh3d",
    x: [0, 0, 1, 1, 0, 0, 1, 1],
    y: [0, 1, 1, 0, 0, 1, 1, 0],
    z: [0, 0, 0, 0, 1, 1, 1, 1],
    i: [7, 0, 0, 0, 4, 4, 6, 6, 4, 0, 3, 2],
    j: [3, 4, 1, 2, 5, 6, 5, 2, 0, 1, 6, 3],
    k: [0, 7, 2, 3, 6, 7, 1, 1, 5, 5, 7, 6],
    intensity: intensity,
    colorscale: [
      [0, 'rgb(255, 0, 255)'],
      [0.5, 'rgb(0, 255, 0)'],
      [1, 'rgb(0, 0, 255)']
    ]
  }
];

Plotly.newPlot('myDiv', data, {});
