与框架中的点相交

Question

since the point's is just a 3d coordinate. It is very hard to intersect with it by cursor or mouse. But in three.js(here is an example https://threejs.org/examples/webgl_interactive_points.html ). The mouse can intersect with points very sensitive. Is there any solution in aframe for this problem? Thank you very much.

Answer 1

A-Frame has a mouse-based raycaster mode. Have you tried that?

https://aframe.io/docs/0.6.0/components/cursor.html#properties_rayorigin

<a-entity cursor="rayOrigin: mouse">

Then add the event listeners and handlers, etc ( https://aframe.io/aframe-school/#/10 )
