COLLADA Physics Compatibility Matrix

Note: This article is a work in progress.

Several tools can export and import some subset of COLLADA 1.4.1 Physics.

We break up COLLADA Physics in different categories (basic collision shapes, advanced collision shapes, constraints, instancing, etc.) and test compatibility between different applications.

This should help to support developers who are interested in COLLADA Physics.


Ageia provides a PhysX plugin for 3ds max that supports COLLADA .dae export (related to NxuStream).

Future compatibility testing

More detailed compatibility testing will follow.

For physics, the features could be naturally split by 3 categories:

  • collision shapes
  • rigidbody features
  • constraint features
and then by:
  • basic
  • advanced

So, for example:

  • Collision detection:
    • Basic: sphere,box,capsule shapes
    • Advanced: convex, (concave) mesh and compounds, inertia tensor (etc.)
  • RigidBody features:
    • Basic: mass, dynamic/static
    • Advanced: initial velocity, hierarchical instancing (etc.)
  • Constraints:
    • Basic: generic D6 joint
    • Advanced: limits, motors, springs, hierarchical instancing

(etc.)
