Package Exports
- triangle-circle-collision
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (triangle-circle-collision) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
triangle-circle-collision
Detects if a circle collides with or is fully inside of a triangle.
var collide = require('triangle-circle-collision')
var triangle = [[350,300], [450,450], [350, 450]]
var point = [25, 15],
radius = 15
//returns true if collision occurs
console.log( collide(triangle, point, radius) )You may also be interested in:
Usage
collide(triangle, circle, radius)
Returns true if the circle intersects a triangle edge or if it's fully enclosed by the triangle. Returns false if no collision occurs.
This uses barycentric coordinates to determine if the point is within the circle, and then tests the circle against each edge of the triangle.
