Solid 3 Collision Detection Library Released

The use of a 32-bit floating-point format to better support games and other interactive applications that run on current PC graphics hardware and consoles.

Penetration-depth computation as a new response type. The penetration depth can be used as an approximation of the contact point and contact plane, which are necessary for physics-based simulation.

Multiple scenes. It is possible to maintain at the same time a sound scene, a scene used for visibility culling, and a scene for physics simulations, without the objects in different scenes interfering with each other.

Expansion of objects. Objects can be expanded spherically, i.e., a margin that defines the radius of the sphere that is 'added' can be set for each object. The object is the set of points whose distance to the shape is at most the margin. Margins are useful for creating objects with rounded edges, or 'sensitive' areas around an object.
