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

.. py:class:: voxcity.simulator_gpu.visibility.workspace.ViewWorkspace(*, key: ViewWorkspaceKey, nx: int, ny: int, nz: int, n_azimuth: int, n_elevation: int, ray_sampling: str, n_rays: Optional[int], elevation_min_degrees: float, elevation_max_degrees: float)

   Pre-allocated Taichi fields for one visibility-ray configuration.

   Parameters are identical to the ray-configuration subset of
   ``ViewCalculator.__init__`` plus the grid dimensions.  All fields are
   created once at construction time.  The caller is responsible for
   reinitialising mask fields before each call to the GPU kernel.

      Raise ``ValueError`` if *voxel_data* shape does not match this workspace.
