Interface Renderer`Internal`

Interface defining the rendering strategy used internally by a Viewer.

A Viewer integrates with an implementation of this interface to manage and render geometry and materials using a supported browser 3D graphics API, such as WebGL or WebGPU.

Example Usage

import { Viewer } from "@xeokit/sdk/viewer";

const myViewer = new Viewer({
    id: "myViewer",
    renderer: new WebGLRenderer({ }) // Or WebGPURenderer, MockRenderer, etc.
});

interface Renderer {
    rendererObjects: { [key: string]: RendererObject };
    get viewer(): Viewer;
    attachSceneModel(sceneModel: SceneModel): void | SDKError;
    attachView(view: View): void | SDKError;
    attachViewer(viewer: Viewer): void | SDKError;
    beginSnapshot(
        viewIndex: number,
        params?: { height: number; width: number },
    ): any;
    clear(viewIndex: number): void | SDKError;
    detachSceneModel(sceneModel: SceneModel): void | SDKError;
    detachView(view: View): void | SDKError;
    detachViewer(): void | SDKError;
    endSnapshot(): any;
    getCapabilities(capabilities: Capabilities): void;
    getNeedsRender(viewIndex: number): boolean | SDKError;
    getSAOSupported(): boolean;
    pick(
        viewIndex: number,
        pickParams: PickParams,
        pickResult?: PickResult,
    ): SDKError | PickResult;
    readSnapshot(params: any): string;
    readSnapshotAsCanvas(params: any): HTMLCanvasElement;
    render(viewIndex: number, params: { force?: boolean }): void | SDKError;
    renderSnapshot(): any;
    setEdgesEnabled(viewIndex: number, enabled: boolean): void | SDKError;
    setImageDirty(viewIndex?: number): void | SDKError;
    setNeedsRebuild(viewIndex: number): void | SDKError;
    setPBREnabled(viewIndex: number, enabled: boolean): void | SDKError;
    setSAOEnabled(viewIndex: number, enabled: boolean): void | SDKError;
