voxcity.simulator_gpu.visibility.workspace
==========================================

.. py:module:: voxcity.simulator_gpu.visibility.workspace

.. autoapi-nested-parse::

   Reusable GPU field workspace for VoxCity visibility calculations.

   A single ``ViewWorkspace`` allocates all Taichi fields required by
   ``ViewCalculator.compute_view_index()`` once and reuses them across calls
   that share the same grid and ray-direction configuration.  This prevents
   GPU memory growth when the optimizer calls the view index hundreds of times
   with the same scene dimensions.

   Cache management is handled by :func:`_get_or_create_view_workspace` and
   :func:`clear_visibility_cache` in ``integration.py``.
