# MeshLine
|
||||
Mesh replacement for ```THREE.Line```
|
||||
|
||||
Instead of using GL_LINE, it uses a strip of triangles billboarded. Some examples:

|

|
||||
### How to use ####
|
||||
|
||||
* Include script
|
||||
* Create and populate a geometry
|
||||
* Create a MeshLine and assign the geometry
|
||||
* Create a MeshLineMaterial
|
||||
* Use MeshLine and MeshLineMaterial to create a THREE.Mesh
|
||||
|
||||
#### Include the script
|
||||
|
||||
Include script after THREE is included
|
||||
```js
|
||||
<script src="THREE.MeshLine.js"></script>
|
||||
```
|
||||
or use npm to install it
|
||||
```
|
||||
npm i three.meshline
|
||||
```
|
||||
and include it in your code (don't forget to require three.js)
|
||||
```js
|
||||
var THREE = require( 'three' );
|
||||
var MeshLine = require( 'three.meshline' );
|
||||
```
|
||||
|
||||
##### Create and populate a geometry #####
|
||||
|
||||
First, create the list of vertices that will define the line. ```MeshLine``` accepts ```THREE.Geometry``` (looking up the ```.vertices``` in it) and ```Array```/```Float32Array```. ```THREE.BufferGeometry``` coming soon, and may be others like ```Array``` of ```THREE.Vector3```.
|
||||
|
||||
```js
|
||||
var geometry = new THREE.Geometry();
|
||||
for( var j = 0; j < Math.PI; j += 2 * Math.PI / 100 ) {
|
||||
var v = new THREE.Vector3( Math.cos( j ), Math.sin( j ), 0 );
|
||||
geometry.vertices.push( v );
|
||||
}
|
||||
```
|
||||
|
||||
##### Create a MeshLine and assign the geometry #####
|
||||
|
||||
Once you have that, you can create a new ```MeshLine```, and call ```.setGeometry()``` passing the vertices.
|
||||
|
||||
```js
|
||||
var line = new MeshLine();
|
||||
line.setGeometry( geometry );
|
||||
```
|
||||
|
||||
Note: ```.setGeometry``` accepts a second parameter, which is a function to define the width in each point along the line. By default that value is 1, making the line width 1 * lineWidth.
|
||||
|
||||
```js
|
||||
line.setGeometry( geometry, function( p ) { return 2; } ); // makes width 2 * lineWidth
|
||||
line.setGeometry( geometry, function( p ) { return 1 - p; } ); // makes width taper
|
||||
line.setGeometry( geometry, function( p ) { return 2 + Math.sin( 50 * p ); } ); // makes width sinusoidal
|
||||
```
|
||||
|
||||
##### Create a MeshLineMaterial #####
|
||||
|
||||
A ```MeshLine``` needs a ```MeshLineMaterial```:
|
||||
|
||||
```js
|
||||
var material = new MeshLineMaterial();
|
||||
```
|
||||
|
||||
By default it's a white material of width 1 unit.
|
||||
|
||||
```MeshLineMaterial``` has several attributes to control the appereance of the ```MeshLine```:
|
||||
|
||||
* ```map``` - a ```THREE.Texture``` to paint along the line (requires ```useMap``` set to true)
|
||||
* ```useMap``` - tells the material to use ```map``` (0 - solid color, 1 use texture)
|
||||
* ```alphaMap``` - a ```THREE.Texture``` to use as alpha along the line (requires ```useAlphaMap``` set to true)
|
||||
* ```useAlphaMap``` - tells the material to use ```alphaMap``` (0 - no alpha, 1 modulate alpha)
|
||||
* ```repeat``` - THREE.Vector2 to define the texture tiling (applies to map and alphaMap - MIGHT CHANGE IN THE FUTURE)
|
||||
* ```color``` - ```THREE.Color``` to paint the line width, or tint the texture with
|
||||
* ```opacity``` - alpha value from 0 to 1 (requires ```transparent``` set to ```true```)
|
||||
* ```alphaTest``` - cutoff value from 0 to 1
|
||||
* ```dashArray``` - THREE.Vector2 to define the dashing (NOT IMPLEMENTED YET)
|
||||
* ```resolution``` - ```THREE.Vector2``` specifying the canvas size (REQUIRED)
|
||||
* ```sizeAttenuation``` - makes the line width constant regardless distance (1 unit is 1px on screen) (0 - attenuate, 1 - don't attenuate)
|
||||
* ```lineWidth``` - float defining width (if ```sizeAttenuation``` is true, it's world units; else is screen pixels)
|
||||
* ```near``` - camera near clip plane distance (REQUIRED if ```sizeAttenuation``` set to false)
|
||||
* ```far``` - camera far clip plane distance (REQUIRED if ```sizeAttenuation``` set to false)
|
||||
|
||||
If you're rendering transparent lines or using a texture with alpha map, you should set ```depthTest``` to ```false```, ```transparent``` to ```true``` and ```blending``` to an appropriate blending mode, or use ```alphaTest```.
|
||||
|
||||
##### Use MeshLine and MeshLineMaterial to create a THREE.Mesh #####
|
||||
|
||||
Finally, we create a mesh and add it to the scene:
|
||||
|
||||
```js
|
||||
var mesh = new THREE.Mesh( line.geometry, material ); // this syntax could definitely be improved!
|
||||
scene.add( mesh );
|
||||
```
|
||||
|
||||
### TODO ###
|
||||
|
||||
* Better miters
|
||||
* Proper sizes
|
||||
* Support for dashArray
|
||||
|
||||
### Support ###
|
||||
|
||||
Tested successfully on
|
||||
|
||||
* Chrome OSX, Windows, Android
|
||||
* Firefox OSX, Windows, Anroid
|
||||
* Safari OSX, iOS
|
||||
* Internet Explorer 11 (SVG and Shape demo won't work because they use Promises)
|
||||
* Opera OSX, Windows
|
||||
