 * `sphereImpostorPosition()` and draw a plain `Mesh` with `TriangleGeometry`,
 * `mesh.count = fluid.particleCount`, disabled frustum culling, and no raycast.
 * Keep `particles.useMatrices` disabled for that path so the simulation does not
 * spend compute bandwidth producing unused per-instance matrices.
 *
 * @param {Object} [options={}] Canonical fluid configuration.
 * @return {PBF|SPH} Configured particle-fluid solver.
