    rle-classify

    This library implements basic geometric queries for narrowband level sets, specifically point and raycasting queries.

    Installation/Usage

    You can install the library using npm:

    npm install rle-classify
    

    And then use it to do basic primitive classification tests:

    //First create a level set
    var bunny = require("rle-rasterize")(require("bunny"));
    
    //Then do a ray-query
    var ray_hit = require("rle-classify").ray(bunny, [10, 0, 0], [-1, 0, 0]);
    console.log("Ray hit info:", ray_hit);
    
    //Point test
    var point_phase = require("rle-classify").point(bunny, [0,0,0]);
    console.log("Point info:", point_phase);
    

    classify.ray(volume, origin, direction[, solid_func])

    Casts a ray against the level set. This takes about O(ray.length * log(volume.length())).

    • volume is a narrowband level set
    • origin is the origin of the ray
    • direction is the ray direction
    • solid_func tests if the volume is solid or not

    Returns a hit record containing the following properties:

    • hit: A boolean flag that checks if the ray hit the volume
    • x: The point of intersection
    • t: The the time of intersection
    • phase: The phase of the volume at the point of intersection

    classify.point(volume, point)

    Tests a point against the level set. This takes O(log(volume.length())) time.

    • volume is a narrowband level set
    • point is the point to test against

    Returns the phase of the level set at point
