Bullet Config Options

The following list is a listing of all config variables defined by the Panda3D Bullet module.

Variable	Value Type	Default	Description
bullet-max-objects	int	1024	Specifies the maximum number of individual objects within a bullet physics world.
bullet-gc-lifetime	int	256	Specifies the lifetime of data clean up be the soft body world info garbage collector.
bullet-broadphase-algorithm	enum	aabb	Specifies the broadphase algorithm to be used by the physics engine. Default value is ‘aabb’ (dynamic aabb tree). A second value is ‘sap’ (sweep and prune).
bullet-sap-extents	float	1000.0	Specifies the world extent in all directions. The config variable is only used if bullet-broadphase-algorithm is set to ‘sap’ (sweep and prune).
bullet-enable-contact-events	bool	false	Specifies if events should be send when new contacts are created or existing contacts get remove. Warning: enabling contact events might create more load on the event queue then you might want! Default value is FALSE.
bullet-solver-iterations	int	10	Specifies the number of iterations for the Bullet contact solver. This is the native Bullet property btContactSolverInfo::m_numIterations.
bullet-additional-damping	bool	false	Enables additional damping on each rigid body, in order to reduce jitter. Additional damping is an experimental feature of the Bullet physics engine. Use with care.”
bullet-additional-damping-linear-factor	float	0.005	Only used when bullet-additional-damping is set to TRUE.
bullet-additional-damping-angular-factor	float	0.01	Only used when bullet-additional-damping is set to TRUE.
bullet-additional-damping-linear-threshold	float	0.01	Only used when bullet-additional-damping is set to TRUE.
bullet-additional-damping-angular-threshold	float	0.01	Only used when bullet-additional-damping is set to TRUE.
