gl-cone3d
=====================
Visualization module for vector fields.

Example

``javascript
var createScene = require('gl-plot3d')
var createConePlot = require('gl-cone3d')
var createMesh = createConePlot.createConeMesh

var wind = require('dataset-wind')

var scene = createScene()

var bounds = [];

var conePlot = createConePlot({
positions: wind.positions,
vectors: wind.vectors,
coneSize: 4,
colormap: 'portland'
}, bounds)

var mesh = createMesh(gl, conePlot)

scene.add(mesh)
`

Install

`
npm i gl-cone3d
`

Basic interface

Constructor

#### var conePlot = require('gl-cone3d')(params, bounds)
Creates a cone plot of a vector field.

* params is an object that has the following properties:

+ positions (Required) An array of positions determining the location of the cones, encoded as arrays
+ vectors (Required) An array of vectors for the vector field, encoded as arrays
+ coneSize Size of the cones, scaled so that the reference cone size for the maximum vector magnitude is 1
+ absoluteConeSize Size of the cones, scaled so that the reference cone size for vector magnitude 1 is one grid unit.
+ coneOffset The position of the cone with regard to the cone location. Ranges from 0 to 1 where 0 puts the center of the cone base at the cone location, and 1 puts the tip at the cone location.
+ colormap` Colormap for the cone plot.

Returns A cone plot object that can be passed to gl-mesh3d.
