RenderBackend

interface RenderBackend

A GPU backend that can draw one engine frame. Implementations: WebGL2 (now), WebGPU (later).

Methods · 5

deleteTexture(id: number): void

Release a texture. Batches still referencing id fall back to solid colour.

dispose(): void
draw(frame: FrameBuffers, camera: CameraState, options: DrawOptions): void

Draw one frame. Batches are bound to the texture named by their texture word (0 = solid colour) and, when they carry a clip rect, scissored to it.

resize(width: number, height: number, dpr: number): void

Resize the drawing buffer. Sizes are CSS pixels; dpr is the device pixel ratio.

uploadTexture(id: number, source: TextureSource, opts?: TextureOptions): void

Create or replace the texture with host id id (must be non-zero; 0 is the built-in solid texture). Shapes reference it through StyleWords.texture.
