Question

我无法与Three.Points相交，但我可以相交THREE.Mesh，下面是我的代码：有人可以帮助我理解我正在犯的错误。当我与Points相交时，我得到的是0。

Declare @Table table (Id varchar(25),Employee_name varchar(25), Address varchar(25))
Insert @Table values
(101,'A1','B1' ),
(102,'A2','B2' ),
(103,'A3','B3' ),
(104,'A3','B4' ),
(105,'A3','B5' )

select field_content as selected_column_content
 from (
select
field_name, field_content
FROM
(Select cast(id as varchar(max)) as id, 
        cast(Employee_name as varchar(max)) as Employee_name,
        cast(address as varchar(max)) as address from @Table) A
unpivot (
    field_content 
    FOR field_name 
    IN (a.id,a.Employee_name,a.address)
    ) AS unpvt
where upper(field_name) = upper('id')
) unpvt1
unpivot 
( Value FOR 
  Column_Name in (unpvt1.field_name)) piv
;

function onDocumentMouseDown( event ) {
                event.preventDefault();
                if(event.which == 1)  {

                    var raycaster = new THREE.Raycaster();
                        raycaster.setFromCamera( mouse, camera );
                        raycaster.params.Points.threshold = 100000; // bigger number = bigger sensitivity
                        var intersects = raycaster.intersectObjects( myobjectsarray,false); // myobject array is array of THREE.Points object 

                            if ( intersects.length > 0 ) {console.log('tadaah',intersects);}

                }
    }

无法相交点
