ndarray-extract-contour
|
|
=======================
|
|
General purpose contour extraction routine generator. This library has a really horrible interface, but it is pretty flexible. It is mostly useful as an internal component, and should not be used generally unless you know what you are doing.
|
|
|
|
As an example of a nicer interface built using this module, take a look at [surface-nets](https://github.com/mikolalysenko/surface-nets).

# Example/documentation
|
|
|
|
```javascript
|
|
var generateContour = require("ndarray-extract-contour")
|
|
|
|
var getContour = generateContour({
|
|
order: [1,0], //Order of array iteration
|
|
arrayArguments: 2, //Take two arrays as input
|
|
scalarArguments: 1, //Take one extra scalar argument
|
|
|
|
//Function to determine phase of a grid cell
|
|
phase: function(a, b, s) {
|
|
|
|
//a = first array argument
|
|
//b = second array argument
|
|
//s = scalar argument
|
|
|
|
return a
|
|
},
|
|
|
|
//Callback for adding vertex to array
|
|
vertex: function(x,y, a00,a01,a10,a11, b00,b01,b10,b11, p00,p01,p10,p11, s) {
|
|
|
|
//Geometry:
|
|
//
|
|
// a11 ---- a10
|
|
// | |
|
|
// | |
|
|
// | |
|
|
// a01 ---- a00
|
|
//
|
|
|
|
//Arguments:
|
|
|
|
// x,y,... = coordinates of vertex in grid index
|
|
// a00,a01,... = components of first array
|
|
// b00,b01,... = components of second array
|
|
// p00,p01,... = phase of all nearby cells
|
|
// s,... = optional scalar arguments
|
|
//
|
|
},
|
|
|
|
//Callback for adding cell
|
|
cell: function(v0,v1, a0,a1, b0,b1, p0,p1, s) {
|
|
|
|
// Geometry:
|
|
//
|
|
// v0
|
|
// |
|
|
// p0 | p1
|
|
// |
|
|
// v1
|
|
|
|
|
|
//Arguments:
|
|
// v0,v1,... = coordinates of vertices of cuboid cell
|
|
// a0,a1 = first array values on front/back cell
|
|
// b0,b1 = second array values on front/back cell
|
|
// p0,p1 = phase values for front/back cell
|
|
// s,... = optional scalar arguments
|
|
}
|
|
})
|
|
|
|
|
|
//How to use it:
|
|
testContour(A, B, S)
|
|
```
