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. In this trick I included an implementation of raycasting algorithm for a polygon selection in a canvas. Background . In this section I briefly explain how the ray casting algorithm can be used for check whether a point is inside or outside the polygon.
