|

| 22 | <div>
|
|---|
| 23 | [page:Vector3 origin] â The origin vector where the ray casts from.<br />
|
|---|
| 24 | [page:Vector3 direction] â The direction vector that gives direction to the ray.<br />
|
|---|
| 25 | [page:Float near] â All results returned are further away then near. Near can't be negative. Default value is 0.<br />
|
|---|
| 26 | [page:Float far] â All results returned are closer then far. Far can't be lower then near . Default value is Infinity.

|
|---|
| 34 |
|
|---|
| 35 | <h3>.[page:Ray ray]</h3>
|
|---|
| 36 | <div>
|
|---|
| 37 | The Ray used for the raycasting.
|
|---|
| 38 | </div>
|
|---|
| 39 |
|
|---|
| 40 | <h3>.[page:float near]</h3>
|
|---|
| 41 | <div>
|
|---|
| 42 | The near factor of the raycaster. This value indicates which objects can be discarded based on the distance.<br />
|
|---|
| 43 | This value shouldn't be negative and should be smaller than the far property.
|
|---|
| 44 | </div>
|

| 45 |
|
|---|
| 46 | <h3>.[page:float far]</h3>
|
|---|
| 47 | <div>
|
|---|
| 48 | The far factor of the raycaster. This value indicates which objects can be discarded based on the distance.<br />
|
|---|
| 49 | This value shouldn't be negative and should be larger than the near property.
|
|---|
| 50 | </div>

| 52 | <h3>.[page:float precision]</h3>
|
|---|
| 53 | <div>
|
|---|
| 54 | The precision factor of the raycaster.

|
|---|
| 58 |
|

| 59 | <h3>.set( [page:Vector3 origin], [page:Vector3 direction] )</h3>
|
|---|
| 60 | <div>
|
|---|
| 61 | [page:Vector3 origin] â The origin vector where the ray casts from.<br />
|
|---|
| 62 | [page:Vector3 direction] â The direction vector that gives direction to the ray.
|
|---|
| 63 | </div>
|
|---|
| 64 | <div>
|
|---|
| 65 | Updates the ray with a new origin and direction.
|
|---|
| 66 | </div>
|
|---|
| 67 |
|
|---|
| 68 | <h3>.intersectObject( [page:Object3D object], [page:Boolean recursive] )</h3>
|
|---|
| 69 | <div>
|
|---|
| 70 | [page:Object3D object] â The object to check for intersection with the ray.<br />
|
|---|
| 71 | [page:Boolean recursive] â If set, it also checks all descendants. Otherwise it only checks intersecton with the object.
|
|---|
| 72 | </div>
|
|---|
| 73 | <div>
|
|---|
| 74 | checks all intersection between the ray and the object with or without the descendants.

| 77 | <h3>.intersectObjects( [page:Array objects], [page:Boolean recursive] )</h3>
|
|---|
| 78 | <div>
|
|---|
| 79 | [page:Array objects] â The objects to check for intersection with the ray.<br />
|
|---|
| 80 | [page:Boolean recursive] â If set, it also checks all descendants of the objects. Otherwise it only checks intersecton with the objects.
|
|---|
| 81 | </div>
|
|---|
| 82 | <div>
|
|---|
| 83 | checks all intersection between the ray and the objects with or without the descendants.
