voxcity.simulator_gpu.visibility.workspace¶
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 _get_or_create_view_workspace() and
clear_visibility_cache() in integration.py.
