Class RenderManager

constructor

• new RenderManager(
      cfg: {
          gpuMemoryReader: GPUMemoryReader;
          meshManager: MeshManager;
          renderContext: RenderContext;
      },
  ): RenderManager

  Creates a RenderManager.

  Parameters

  • cfg: {
        gpuMemoryReader: GPUMemoryReader;
        meshManager: MeshManager;
        renderContext: RenderContext;
    }

    • gpuMemoryReader: GPUMemoryReader

      Read-only access to GPU memory.

    • meshManager: MeshManager

      Provides sorted mesh batches and render-pass queries.

    • renderContext: RenderContext

      Shared render context (WebGL state, flags, configs).

  Returns RenderManager

drawOps

infiniteGrid

skyRenderer

init

• init(): SDKResult<void>

  Initializes draw operations and activates supported WebGL extensions.

  Returns SDKResult<void>

  SDKResult indicating success or failure.

  Remarks

  • Must be called before render
  • Draw operations are pooled; this may reuse previously created programs

render

• render(
      rendererView: ViewRenderState,
      options: { clear: boolean },
  ): SDKResult<any>

  Renders a single ViewRenderState.

  This method:

  • Configures global WebGL state
  • Classifies mesh batches into render bins
  • Executes multi-pass rendering in correct order
  • Cleans up GPU state after rendering

  Parameters

  • rendererView: ViewRenderState

    Renderer-side state for the target view.
  • options: { clear: boolean }

    • clear: boolean

      Whether to clear color/depth buffers before rendering.

  Returns SDKResult<any>

  Throws

  SDKInternalException If called before init.

webglContextRestored

• webglContextRestored(): SDKResult<void>

  Reinitializes everything that holds GL state after a context restore.

  Context loss invalidates every GPU resource — programs, textures, framebuffers, renderbuffers — across the whole renderer. drawOps has its own in-place restore hook (the program pool is shared, so it needs to recompile rather than be reconstructed); everything else (sky, grid, SAO pipeline, shadow pipeline, post-process chain) is torn down and re-initialised through init so each owner walks back through its own lazy-construction path with a fresh GL context.

  Returns SDKResult<void>
