L@ Cible has released Opcode 1.2, which according to his site, is a new small collision detection library. Here are some of features new to Opcode 1.2:
new VolumeCollider base class
simplified callback setup
you can now use callbacks or pointers (setup at compile time)
destination array not needed anymore in the RayCollider (faster in-out tests)
renamed classes: AABBRayCollider => RayCollider, AABBSphereCollider => SphereCollider
the sphere query now only returns a list of faces (extra info discarded). On the other hand it’s a lot faster.
OBB, AABB and planes queries. Original OBB and AABB queries contributed by Erwin de Vries.
cosmetic changes in OPC_BoxBoxOverlap.h contributed by Gottfried Chen
some inlining problems fixed
faster ray-mesh tests using the separating axis theorem
new split value in AABB tree construction (contributed by Igor Kravtchenko). Provides faster queries most of the time.
improved temporal coherence for sphere & AABB queries (works in “All contacts” mode)
