extent

• get extent(): [number, number, number]

  World-space extent along each axis (worldMax - worldMin).

  Returns [number, number, number]

StaticbakeFromMesh

• bakeFromMesh(ctx: RenderContext, opts: SdfBakeOptions): SdfVolume

  Bakes a signed distance field from a triangle mesh using a single compute dispatch. Returns immediately after submitting the command buffer; the texture is usable once the device has consumed the submission (typical WebGPU resource semantics).

  Parameters

  • ctx: RenderContext
  • opts: SdfBakeOptions

  Returns SdfVolume

StaticfromMesh

• fromMesh(
      ctx: RenderContext,
      mesh: Mesh,
      opts?: {
          resolution?: number | [number, number, number];
          padding?: number;
          worldOffset?: [number, number, number];
      },
  ): SdfVolume

  Bakes an SDF from a Mesh created with keepData: true. Extracts positions from the retained interleaved vertex data (stride = VERTEX_STRIDE) and forwards to bakeFromMesh.

  worldOffset translates the mesh positions before baking so the SDF's AABB aligns with where the mesh is rendered in world space (the particle pass samples the SDF in world coordinates). For a mesh drawn at Mat4.translation(x,y,z), pass worldOffset: [x, y, z]. Defaults to [0,0,0] — mesh local == world.

  Throws if the Mesh wasn't built with keepData: true.

  Parameters

  • ctx: RenderContext
  • mesh: Mesh
  • Optionalopts: {
        resolution?: number | [number, number, number];
        padding?: number;
        worldOffset?: [number, number, number];
    }

  Returns SdfVolume

destroy

• destroy(): void

  Returns void
