Ray casting javascript

TīmeklisThe problem is: THREE.JS has only a raycasting class which can be used for collisions. I figured it would be possible if I casted 8 rays from my character to the points of an imaginary cube around the character (simulating an AABB box). I realize a sphere would be much better, but I wouldn't know how to do that using rays. Tīmeklis2008. gada 28. dec. · To to do that, we’ll need to figure out what is visible in the player’s current field of vision; for that purpose we’ll be using a technique called raycasting. To understand this, imagine rays being shot or “cast” out from the viewer in all directions within their field of view.

Tīmeklis2024. gada 11. maijs · 1 Answer Sorted by: 2 The problem is that you are performing ray casting against a skinned mesh. And three.js is currently ( r128) not able to compute proper bounding volumes for this type of 3D object. Bounding volumes however are important for ray casting since they are used to detect early outs. Tīmeklis2013. gada 26. jūl. · Ray casting algorithm is one popular way to do it.

TīmeklisMost implementations of the ray casting algorithm consecutively check intersections of a ray with all sides of the polygon in turn. In this case the following problem must be addressed. If the ray passes exactly through a vertexof a polygon, then it will intersect 2 segments at their endpoints. TīmeklisComposite films have beenprepared using solution casting technique.
