gl-surface3d
===============
3D parametric surface plotting, compatible with gl-vis.

Example

``javascript
var createScene = require('gl-plot3d')
var createSurfacePlot = require('gl-surface3d')
var ndarray = require('ndarray')
var fill = require('ndarray-fill')
var diric = require('dirichlet')

var scene = createScene()

//Create field
var field = ndarray(new Float32Array(512*512), [512,512])
fill(field, function(x,y) {
return 128 diric(10, 10.0(x-256)/512) diric(10, 10.0(y-256)/512)
})

//Create surface plot
var surface = createSurfacePlot({
gl: scene.gl,
field: field
})

scene.add(surface)
`

Here is what this should look like:

Test it in your browser (requires WebGL)

Install

`
npm install gl-surface3d
`

Basic Interface

Constructor

#### var surface = require('gl-surface3d')(params)
Creates a surface plot object. params is an object with any of the following parameters

* gl is a WebGL context
* field a new 2D field encoded as an ndarray
* coords is an array of 3 2D fields, each encoded as ndarrays (for parameteric surfaces)
* intensity a 2D intensity field (defaults to field or coords[2] is not present)
* colormap the name of the new color map for the surface (see list of names in colormap docs)
* intensityBounds sets the intensity range for the colormap
* ticks is a pair of arrays of ticks representing the spacing of the points for the axes of the surface
* showSurface if set, draw the surface
* showContour if set, draw contour lines
* contourWidth the width fo the contour lines
* contourTint the amount of tint of the contour lines
* contourColor the color of the contour line tint
* levels an array of arrays representing the level of the isolines.
* dynamicWidth the width of the dynamic isolines
* dynamicColors the color of the dynamic isolines
* dynamicTint the tint of the dynamic isolines
* vertexColor interpolate color in fragment or vertex shader, useful for discontinuous functions (ref)

Methods

#### surface.update(params)
Modify the surface. params is an object with the same properties as the constructor
