Fix child shape filtering by lenroe · Pull Request #1559 · newton-physics/newton

lenroe · 2026-02-06T20:18:18Z

Fix collision filter pairs not being updated for child body shapes when approximate_meshes() (or any shape addition) adds new shapes to a parent body after joints exist (#1378).

Changes

Add joint_children dictionary to track parent body → child bodies mapping
Update add_shape() to filter new shapes with existing child body shapes
Add test

Note: There is some preexisting ambiguity in the collision_filter_parent API, which seems to be a flag for both shapes and joints.

Summary by CodeRabbit

Improvements
- Better tracking of parent–child links in articulations, improving stability of multi-body interactions.
- Collision-filter propagation now includes child bodies and newly added shapes so exclusions remain correct across connected parts.
- World merges and copy operations preserve articulation relationships so collision behavior stays consistent after replication.
Tests
- Added a test verifying collision-filter consistency when bodies gain additional shapes, including child-body pairings.

📝 Walkthrough

Walkthrough

Adds a joint_children mapping to ModelBuilder, changes joint_parents semantics to map child→parents, and updates joint creation, merge/transform, DFS rebuild, and shape-add logic to maintain bidirectional parent↔child relationships and propagate collision-filter pairs to child bodies.

Changes

Cohort / File(s)	Summary
Builder internals & joint mappings `newton/_src/sim/builder.py`	Add public `joint_children: dict[int, list[int]]`; reinterpret `joint_parents` as child→parents; initialize and maintain both maps in `ModelBuilder.__init__`, `add_joint`, merge/transform paths, and DFS rebuild.
Collision-filter propagation `newton/_src/sim/builder.py`	Extend `add_shape` to propagate collision-filter pairs to/from child bodies using `joint_children` (in addition to ancestor propagation via `joint_parents`); call `add_shape_collision_filter_pair` for child shape pairings.
Tests `newton/tests/test_model.py`	Add `test_approximate_meshes_collision_filter_child_bodies` to verify collision-filter pairs propagate correctly across parent↔child bodies after adding extra shapes.

324-398: Well-structured regression test covering the fix.

The test thoroughly validates collision-filter propagation in both directions (parent→child and child→parent) when shapes are added after joints exist. The use of add_link() is correct here (addressed from previous feedback).

One minor note: the method name references approximate_meshes but the test doesn't call approximate_meshes() — it directly adds shapes to simulate the post-joint shape addition. Consider renaming to something like test_collision_filter_post_joint_shape_addition to more accurately describe what's being tested, since the test is really about add_shape() behavior, not approximate_meshes() specifically.

In `@newton/_src/sim/builder.py`:
- Around line 704-705: The joint_parents/joint_children dicts get out of sync
after bulk mutations to the lists (e.g., in add_builder() and
collapse_fixed_joints()), causing add_shape()'s collision filtering to use stale
data; after any code path that mutates joint_parent or joint_child (such as the
list-extend in add_builder() or the rebuild in collapse_fixed_joints()),
reinitialize self.joint_parents and self.joint_children to empty dicts and
repopulate them by iterating i from 0 to self.joint_count-1, reading parent =
self.joint_parent[i] and child = self.joint_child[i], and appending parent into
self.joint_parents[child] and child into self.joint_children[parent] only if not
already present so the maps always reflect the current lists used by
add_shape().

In `@newton/tests/test_model.py`:
- Around line 334-336: The test creates body0, body1, body2 with
builder.add_body(), but then attaches explicit joints to those bodies, causing
duplicate free joints; replace builder.add_body() with builder.add_link() for
body0, body1, and body2 so they are created as links (no auto free joint) before
you add the explicit joints to them (referencing the variables body0, body1,
body2 and the explicit joint-creation calls that follow).

🧹 Nitpick comments (3)

newton/tests/test_model.py (2)
324-324: Test name is misleading — approximate_meshes is never called.

The test name says test_approximate_meshes_collision_filter_child_bodies, but it never invokes approximate_meshes(). It actually validates that add_shape_*() calls after joints exist produce the correct collision filter pairs. Consider renaming to something like test_add_shape_collision_filter_child_bodies to accurately describe what's being tested.

362-398: Consider adding a negative assertion for non-adjacent bodies.

The test verifies that filter pairs do exist between adjacent bodies (body0↔body1, body1↔body2). However, it doesn't verify that non-adjacent bodies (body0↔body2) do not have spurious filter pairs for the newly added shapes. Adding a negative check would strengthen the test:
Suggested addition after line 398
        # Verify: body0 and body2 shapes should NOT be filtered (non-adjacent)
        for b0_shape in [shape0_initial, shape0_extra1, shape0_extra2]:
            expected_pair = normalize_pair(b0_shape, shape2_initial)
            self.assertNotIn(
                expected_pair,
                filter_set,
                f"Non-adjacent body0 shape {b0_shape} should NOT filter with body2 shape {shape2_initial}",
            )
newton/_src/sim/builder.py (1)
2546-2553: Avoid duplicate entries in joint_parents.

joint_children guards against duplicates but joint_parents does not. Multiple joints between the same bodies can yield redundant filter pairs later. Consider mirroring the duplicate check for symmetry.
♻️ Proposed fix
-        if child not in self.joint_parents:
-            self.joint_parents[child] = [parent]
-        else:
-            self.joint_parents[child].append(parent)
+        if child not in self.joint_parents:
+            self.joint_parents[child] = [parent]
+        elif parent not in self.joint_parents[child]:
+            self.joint_parents[child].append(parent)

In `@newton/_src/sim/builder.py`:
- Around line 703-706: The merge in add_builder() extends the joint_parent and
joint_child lists but never rebuilds the joint_parents and joint_children dicts,
so parent-child relationships are missing for shapes added after a merge; update
add_builder() to rebuild those dicts after extending the arrays (or factor the
mapping logic into a helper and call it from both add_joint() and add_builder())
so that joint_parents and joint_children reflect the combined
joint_parent/joint_child state and collision filter pairs remain correct.

🧹 Nitpick comments (3)

newton/_src/sim/builder.py (1)
4056-4059: Skip non-colliding child shapes when adding filter pairs.

Avoid adding filter pairs for shapes that can’t collide; it reduces filter-set bloat and mirrors the checks used elsewhere.

newton/tests/test_model.py (2)
324-327: Missing docstring for test method.

Most of the newer test methods in this class (e.g., test_add_particles_grouping, test_world_grouping) include a docstring. Adding one here would improve consistency and clarify what scenario is being exercised.
Proposed docstring
     def test_approximate_meshes_collision_filter_child_bodies(self):
+        """Test that collision filter pairs are updated for child body shapes when new shapes are added after joints exist."""
         def normalize_pair(a, b):
             return (min(a, b), max(a, b))
331-348: Consider using add_link() directly instead of add_body() for clearer, more representative test setup.

The test uses add_body() (lines 334–336), which internally creates a link, free joint, and single-body articulation for each body. Then it adds a redundant free joint for body0 (line 345) and creates another articulation (line 348). This doesn't align with the documented use pattern: the add_body() docstring explicitly states it creates a "single-body articulation" and recommends using add_link() + joints + add_articulation() directly for multi-body chains.

While the redundant joint is harmlessly prevented by deduplication logic (line 2552 in builder.py), the overall setup is confusing and doesn't reflect how approximate_meshes() would be used in practice. A clearer approach:
Suggested refactor using add_link()
         builder = ModelBuilder()
 
         # Create a chain of 3 links (like an articulation)
-        body0 = builder.add_body()
-        body1 = builder.add_body()
-        body2 = builder.add_body()
+        body0 = builder.add_link()
+        body1 = builder.add_link()
+        body2 = builder.add_link()
 
         # Add initial shapes to each body (like mesh shapes before decomposition)
         shape0_initial = builder.add_shape_sphere(body=body0, radius=0.1)
         shape1_initial = builder.add_shape_sphere(body=body1, radius=0.1)
         shape2_initial = builder.add_shape_sphere(body=body2, radius=0.1)
 
         # Create joints (establishes parent->child relationships)
         # body0 is parent of body1, body1 is parent of body2
         joint_free = builder.add_joint_free(parent=-1, child=body0)
         joint0 = builder.add_joint_revolute(parent=body0, child=body1, axis=(0, 0, 1))
         joint1 = builder.add_joint_revolute(parent=body1, child=body2, axis=(0, 0, 1))
         builder.add_articulation(joints=[joint_free, joint0, joint1])
This removes the confusing redundant articulation setup and makes the test directly demonstrate the documented pattern for building multi-body chains.
