Class AbstractWebGLRenderer`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.

`Protected`extractLights

extractLights(scene: Scene): LightDataInterface
Extracts all lights from the scene for rendering.
Parameters

- Optionalconfig: EngineOptions
Returns Promise<void>
Inherited from AbstractRenderer.initialize
- Defined in renderers/AbstractRenderer.ts:54

`Abstract`render

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