Three.js Raycaster.intersectobject Do Not Intersect When Three.points Has Only 1 Vertex Or Has Vertexs Arranged In Line

I spent several hours to understand this problem. For some inexplicable reason (for me) raycaster.intersectObject( pointCloud ); do not intersect my 'pointCloud' Object when it ha

Solution 1:

@WestLangley gave me the answer in GitHub.

He said: "Your bounding box has no volume. Try this and report back:

pointCloud.geometry.boundingBox = null;

"

I tried and it worked out of the box!. And the detection is working even better than before.

Something that @Beiller pointed out in the comments, and is important to include here I think.

I had a call to

this.geometry.computeBoundingBox();

...for my geometry, but the points are not volumes, so single point or aligned (in one of the three axis: x, y or z) points are not detected. Using instead:

this.geometry.computeBoundingSphere() 

solve the problem too.
