Scene
WL.Scene
Provides global scene functionality like raycasting.
Kind: static class of WL
.activeViews ⇒ Array.<ViewComponent>
Kind: instance property of Scene
Returns: Array.<ViewComponent> - currently active view components
.rayCast(o, d, group)
Cast a ray through the scene and find intersecting objects.
The resulting ray hit will contain up to 4 closest ray hits, sorted by increasing distance.
Kind: instance method of Scene
Note: The returned RayHit object is owned by the Scene instance and
will be reused with the next rayCast call.
| Param | Type | Description |
|---|---|---|
| o | Array.<number> | Ray origin |
| d | Array.<number> | Ray direction |
| group | number | Collision group to filter by: only objects that are part of given group are considered for raycast. |
.addObject(parent) ⇒ Object
Add object to the scene
Kind: instance method of Scene
Returns: Object - newly created object
| Param | Type | Description |
|---|---|---|
| parent | Object | Parent object or null |
.addObjects(count, parent, componentCountHint) ⇒ Array.<Object>
Batch-add objects to the scene
Will provide better performance for adding multiple objects (e.g. > 16) than calling addObject repeatidly in a loop.
By providing upfront information of how many objects will be required, the engine is able to batch-allocate the required memory rather than convervatively grow the memory in small steps.
Experimental: This API might change in upcoming versions.
Kind: instance method of Scene
Returns: Array.<Object> - newly created objects
| Param | Type | Description |
|---|---|---|
| count | number | Number of objects to add |
| parent | Object | Parent object or null, default null |
| componentCountHint | number | Hint for how many components in total will be added to the created objects afterwards, default 0. |
.load(filename)
Load a scene file (.bin)
Will replace the currently active scene with the one loaded from given file. It is assumed that JavaScript components required by the new scene were registered in advance.
Kind: instance method of Scene
| Param | Description |
|---|---|
| filename | Path to the .bin file |
