Dusting Off the Classics: A Look Back at Havok SDK 2010 2.0-r1

2. The Core: The Physics Engine Architecture

The heart of the 2010.2.0-r1 SDK is the hkPhysicsWorld. Unlike modern engines that often abstract physics away, Havok 2010 required a deep understanding of the simulation island architecture. havok sdk 2010 2.0-r1

For developers working with the 2010 2.0-r1 release, the technical setup was strictly defined: Dusting Off the Classics: A Look Back at Havok SDK 2010 2

2.1 The Core Modules

| Module | Purpose | | :--- | :--- | | hkBase | Memory allocation, containers (hkArray, hkMap), string management. Replaced the older hkString system with SSE-optimized allocators. | | hkPhysics | The heart. Rigid bodies, constraints, collision queries, and the hkpWorld simulation island system. | | hkCollide | Narrow-phase collision detection. Supported primitive-sphere, capsule, box, convex hull, and mesh shapes. Included GJK/EPA for convex vs. convex. | | hkAnimation | The Havok Animation engine (often bundled separately, but integrated in 2010.2.0). Included retargeting, blending, and bone masks. | | hkBehavior | An early version of Havok Behavior (predecessor to Havok AI and full Behavior), used for scripted physical interactions. | Requires vcomp90

That markForWrite() / unmarkForWrite() lock pattern drove everyone crazy, but it also meant zero race conditions on the PS3’s SPUs.

• Requires vcomp90.dll / vcomp100.dll (OpenMP) – ensure they are installed.
• May need D3DCompiler_43.dll for cloth/visual debugger rendering.
