Class AbstractRenderer`Abstract`

Base class for all renderer implementations.

Backends are expected to implement defensive rendering strategies to prevent "silent failures":

Validate that all uniforms defined in a material's layout are actually present in the compiled shader.
Log warnings or errors if expected data structures (e.g., WebGPU uniform blocks) are missing or misaligned.
Provide fallback values or behaviors if specific features (like rounded rects) are not supported by the hardware.

Accessors

clearColor

get clearColor(): Color
Gets the clear color of the renderer.

Returns Color
Implementation of Renderer.clearColor
- Defined in renderers/AbstractRenderer.ts:85

quality

get quality(): QualityConfig
Gets the global quality settings of the renderer.

Returns QualityConfig
Implementation of Renderer.quality
- Defined in renderers/AbstractRenderer.ts:90

Methods

destroy

destroy(): void
Destroys the renderer and releases its resources.

Returns void
Implementation of Renderer.destroy
- Defined in renderers/AbstractRenderer.ts:75

`Protected`extractLights

extractLights(scene: Scene): LightDataInterface
Extracts all lights from the scene for rendering.
Parameters
- scene: Scene
  The scene to extract lights from.
Returns LightDataInterface
An object containing all extracted light data.
- Defined in renderers/AbstractRenderer.ts:99

`Abstract`initialize

initialize(
    canvas: HTMLCanvasElement,
    attributes?: Record<string, unknown>,
    config?: EngineOptions,
): Promise<void>
Initializes the renderer.
Parameters
- canvas: HTMLCanvasElement
- Optionalattributes: Record<string, unknown>
- Optionalconfig: EngineOptions
Returns Promise<void>
Implementation of Renderer.initialize
- Defined in renderers/AbstractRenderer.ts:54

`Abstract`render

render(scene: Scene, vpMatrix: Float32Array, camPos?: Vector3D): void
Renders a scene.

`Abstract`setRenderTarget

setRenderTarget(
target: RenderTarget | RenderTargetCube | null,
