tess API reference

This reference documents the supported C++ API generated from the installed headers. Use the version-relative navigation above to return to the authored documentation, its learning paths, or the reference map.

The 1.x release line preserves the documented stable source API. See the stability policy for its scope.

Core worlds

• tess::Shape fixes the world, chunk, and lattice dimensions at compile time.
• tess::FieldSchema declares the typed fields in each chunk page.
• tess::World combines shape, schema, and dense or sparse residency.

Pathfinding

• tess::PathRequest carries one start and goal.
• tess::PathScratch owns reusable A* work storage.
• tess::DistanceFieldProduct retains a dense multi-goal distance product for reuse.

Simulation

• tess::OperationBatch collects declared world edits for validation and execution.
• tess::Schedule runs deterministic phase-ordered tasks.
• tess::DeltaFrame publishes versioned changes to a consumer-owned presentation layer.

Diagnostics

• tess::diagnostics::DiagnosticsSnapshot captures path, queued-phase, timing, trace, and allocation state.
• tess::diagnostics::FlowAccounting accounts lifecycle admission, retention, and terminal outcomes.

Optional integrations

• tess::EnttTilePositionAdapter and tess::FlecsTilePositionAdapter bind external entity storage without transferring ownership.
• tess::gpu::WebGpuBackend implements the optional GPU transport boundary; pathfinding remains on the CPU.
