How to select ObjectBillboards?

[liu.yan]

ObjectBillboards can not be selected by functions like World::getIntersection, World::getCollision.

These functions always returns a null pointer.

In editor, i can select ObjectBillboards by dragging a box which completely surround the object. But I want to select this object by single click(not select by box).

how to do that?

 

Code in select.cpp demonstrate the problem.

Hi Liu,

 

Well, it's not so obvious how to find the intersection with a billboard which is always oriented against the camera.

That's why it's currently not implemented at all.

 

We've thought about possible implementation and the best idea yet is to find the intersection with the billboard bound sphere instead.

Sorry for pushing so old issue, but have you made implementation of intersection with the billboard or still not?

Hi Artem,

Unfortunately, there is no intersection yet available for some objects that are mostly "exist" on GPU (such as Grass, Decals, Billboards). We considering to add some kind of GPU intersection for this objects, but I can't give you any ETA for this, sorry.
