Ray casting

[LamprosPitsillos]

var center = turf.point([-122.3116, 47.6623]);
var radius = 0.5;
var bearing1 = 15;
var bearing2 = 65;

var sector = turf.sector(center, radius, bearing1, bearing2);

const poly = turf.polygon([[
    [-122.3104, 47.6627],
    [-122.3071, 47.6627],
    [-122.3071, 47.6644],
    [-122.3104, 47.6644],
    [-122.3104, 47.6627]
  ]],
  {stroke: '#0FF', fill: '#0FF', 'fill-opacity': 0.3, 'stroke-width': 6}
);

return turf.featureCollection([poly, sector]);

Is there anything in turf to help me with achieving the above? I imagine the Sector is a camera and want to show what it can "see"

Hi @LamprosPitsillos. Can you please be a bit more specific about what shape you're hoping to get back? Maybe as outlines as it's not clear what the different colour shadings are meant to mean.

This is more or less what i am looking for, the squear to obstruct the section in a way tha looks like ray tracing.

The use case again is :

Section = Camera FOV
Square = Obstacle

Thanks for the extra detail. I don't think there is any easy way to do this in Turf. You might be better looking at a library that specialises in ray tracing, and doing any coordinate conversion necessary.
