Constructors ​

constructor ​

• new copperSceneOnDemond(container, renderer, opt?)

opt.controls picks the controls class, as it already did on copperScene. New in 3.9.0 -- this class hardcoded OrbitControls before, so passing the option produced no error and no effect.

The DEFAULT stays OrbitControls, which is what this class has always built. It differs from copperScene's default (Copper3dTrackballControls) on purpose: changing it would silently swap the controls under every existing on-demand viewer.

Note that the renderer's own options.controls is deliberately NOT consulted. It has never had any effect here, so honouring it now would change behaviour for anyone who set it and never noticed.

Methods ​

addLights ​

▸ addLights(): void

Returns ​

void

Inherited from ​

baseScene.addLights

Defined in ​

src/Scene/baseScene.ts:142

addObject ​

▸ addObject(obj): void

Parameters ​

Returns ​

void

Inherited from ​

baseScene.addObject

Defined in ​

src/Scene/baseScene.ts:138

addPreRenderCallbackFunction ​

▸ addPreRenderCallbackFunction(callbackFunction): number

Registers a per-frame callback and returns its id, for removePreRenderCallbackFunction.

Parameters ​

Returns ​

number

Inherited from ​

baseScene.addPreRenderCallbackFunction

Defined in ​

src/Scene/commonSceneMethod.ts:109

addSubView ​

▸ addSubView(): HTMLDivElement

create a new sub view to display models

Returns ​

HTMLDivElement

Inherited from ​

baseScene.addSubView

Defined in ​

src/Scene/commonSceneMethod.ts:159

confirmResize ​

▸ confirmResize(): void

Returns ​

void

Defined in ​

src/Scene/copperSceneOnDemond.ts:153

createDemoMesh ​

▸ createDemoMesh(): void

Returns ​

void

Inherited from ​

baseScene.createDemoMesh

Defined in ​

src/Scene/commonSceneMethod.ts:82

dispose ​

▸ dispose(): void

Releases what this scene attached OUTSIDE itself.

The resize listener the constructor puts on window used to have no counterpart: every scene ever created stayed subscribed for the life of the page, kept alive by the closure, and went on calling requestRenderIfNotRequested -- and so onWindowResize, which resizes the SHARED renderer -- long after it stopped being displayed. An app that creates a scene per case leaks one of those per case.

Does not touch the scene graph or the renderer: what a scene's contents are worth keeping is the caller's decision, and the renderer is shared with every other scene. disposeScene(renderer, name) is the one that tears the contents down.

Deliberately NOT controls.dispose(). That path ends in domElement.style.touchAction = "", and every scene here shares one canvas -- only connect() sets it back to "none". Disposing one scene's controls would kill touch rotation on the canvas for the rest of the session. Disabling them is enough.

Safe to call twice.

Returns ​

void

Defined in ​

src/Scene/copperSceneOnDemond.ts:181

fitView ​

▸ fitView(preset, aspect, bounds, margin?): boolean

Re-frames the camera on bounds, keeping the preset's view direction and up and replacing only its distance. Returns false when there is nothing to do -- an orthographic camera (no field of view to fit against), or a preset whose eye sits exactly on its target.

Does not render: the caller decides when to draw, which matters here because this scene renders on demand.

setCameraPose ​

▸ setCameraPose(pose): void

Moves the camera to pose and syncs the controls' orbit pivot with it. Without that last part the next drag silently undoes the move -- see Controls/setCameraPose.ts.
