================================================================

.. py:class:: voxcity.simulator_gpu.solar.reflection.OptimizedReflectionSolver(n_surfaces: int, max_svf_entries: int, n_reflection_steps: int = 3)

   Optimized GPU solver for multi-bounce radiation reflections.

   This replaces the per-step kernel launches with fused operations
   that run the entire reflection loop on GPU without CPU intervention.

   .. py:attribute:: max_svf_entries


   .. py:attribute:: n_reflection_steps
      :value: 3



   .. py:method:: solve_reflections_fused(initial_sw: ti.template(), albedo: ti.template(), svf: ti.template(), svf_source: ti.template(), svf_target: ti.template(), svf_vf: ti.template(), svf_trans: ti.template(), svf_nnz: taichi.i32, n_steps: taichi.i32)

      Fused kernel for complete multi-bounce reflection computation.

      This runs all reflection iterations in a single kernel launch,
      eliminating CPU-GPU synchronization overhead between steps.

      Uses ping-pong buffers to avoid race conditions between iterations.



   .. py:method:: get_results()

      Get accumulated totals as numpy arrays.
