Legacy modules and camelCase remain available with `DeprecationWarning` for DART 7.x and are slated for removal in DART 8.0 (see `DARTPY_ENABLE_LEGACY_MODULES`, `DARTPY_WARN_ON_LEGACY_MODULES`, `DARTPY_ENABLE_SNAKE_CASE`, `DARTPY_WARN_ON_CAMELCASE`). - Moved the generic optimization primitives (`Function`, `Problem`, `Solver`, `GradientDescentSolver`) under `dart/math/optimization`; the legacy `` headers and `dart::optimizer::*` namespace now forward (with deprecation notices) to the new `dart::math::*` definitions. - Dropped the deprecated `docker/dev/v6.15` images; use the maintained v6.16 images instead. - Renamed the OpenSceneGraph GUI component/target to `gui`/`dart-gui` (previously `gui-osg`/`dart-gui-osg`) and replaced the `DART_BUILD_GUI_OSG` toggle with `DART_BUILD_GUI`. diff --git a/docs/onboarding/README.md b/docs/onboarding/README.md index 909601f86c8ba..7c33a9c32e968 100644 --- a/docs/onboarding/README.md +++ b/docs/onboarding/README.md @@ -558,13 +558,10 @@ graph TB **Key Modules**: -- `dartpy.math` - Mathematical utilities and Eigen↔NumPy conversion -- `dartpy.dynamics` - Skeletons, BodyNodes, Joints, IK -- `dartpy.collision` - Collision detection backends -- `dartpy.constraint` - Constraint solving -- `dartpy.simulation` - World simulation +- `dartpy` (top-level) - Core classes/functions (math, dynamics, collision, simulation, constraint, optimizer) exposed in snake_case +- `dartpy.io` - File parsers (URDF, SDF, SKEL, MJCF) [alias for legacy `utils`] - `dartpy.gui` - 3D visualization with OSG and ImGui -- `dartpy.utils` - File parsers (URDF, SDF, SKEL, MJCF) +- Legacy `dartpy`/`math`/`dynamics`/`collision`/`simulation`/`constraint`/`optimizer`/`utils` remain importable in DART 7.x but emit `DeprecationWarning` and will be removed in DART 8.0. **Key Files**: @@ -818,20 +815,20 @@ sequenceDiagram participant NumPy as NumPy Python->>dartpy: import dartpy - Python->>dartpy: world = dartpy.simulation.World() + Python->>dartpy: world = dartpy.World() dartpy->>DART: World::create() - Python->>dartpy: skel = dartpy.dynamics.Skeleton.create() + Python->>dartpy: skel = dartpy.Skeleton.create() dartpy->>DART: Skeleton::create() - Python->>dartpy: world.addSkeleton(skel) + Python->>dartpy: world.add_skeleton(skel) dartpy->>DART: World::addSkeleton() loop Simulation Python->>dartpy: world.step() dartpy->>DART: World::step() - Python->>dartpy: q = skel.getPositions() - dartpy->>DART: Skeleton::getPositions() + Python->>dartpy: q = skel.get_positions() + dartpy->>DART: Skeleton::get_positions() DART->>NumPy: convert Eigen to ndarray NumPy-->>Python: positions array end @@ -1207,7 +1204,7 @@ dart_gui/ ```python import dartpy as dart from dartpy.gui import Viewer, RealTimeWorldNode -from dartpy.utils import DartLoader +from dartpy.io import DartLoader ``` --- diff --git a/docs/onboarding/python-bindings.md b/docs/onboarding/python-bindings.md index e1825227d7e93..10a0e4de1d579 100644 --- a/docs/onboarding/python-bindings.md +++ b/docs/onboarding/python-bindings.md @@ -45,19 +45,21 @@ ### Module Structure -dartpy organizes DART's C++ API into Python modules: +dartpy now flattens most symbols onto the top-level package to avoid deep +namespaces: ``` dartpy/ -├── math # Eigen integration, geometry utilities -├── dynamics # Skeletons, BodyNodes, Joints -├── collision # Collision detection backends -├── constraint # Constraint solving -├── simulation # World simulation -├── utils # File parsers (URDF, SDF, SKEL, MJCF) +├── io # File parsers (URDF, SDF, SKEL, MJCF) └── gui # 3D visualization (OpenSceneGraph + ImGui) ``` +- Core classes/functions (dynamics, collision, math, simulation, constraint, + optimizer) are promoted onto `dartpy` directly. +- Legacy submodules remain importable in DART 7.x but will be removed in DART + 8.0.
