Member Data Documentation

double gazebo::physics::ODESurfaceParams::bounce

bounce restitution coefficient [0,1], with 0 being inelastic, and 1 being perfectly elastic.

double gazebo::physics::ODESurfaceParams::bounceThreshold

minimum contact velocity for bounce to take effect, otherwise the collision is treated as an inelastic collision.

See Also
http://www.ode.org/ode-latest-userguide.html#sec_7_3_7
double gazebo::physics::ODESurfaceParams::cfm

Constraint Force Mixing parameter.

See for example http://www.ode.org/ode-latest-userguide.html#sec_3_8_0 for more details.

double gazebo::physics::ODESurfaceParams::erp

Error Reduction Parameter.

See for example http://www.ode.org/ode-latest-userguide.html#sec_3_8_0 for more details.
FrictionPyramid gazebo::physics::ODESurfaceParams::frictionPyramid

Friction pyramid parameters (mu1, mu2).

Note that the primary friction pyramid direction can be specified by fdir1, otherwise a vector constrained to be perpendicular to the contact normal in the global y-z plane is used.

double gazebo::physics::ODESurfaceParams::maxVel

Maximum interpenetration error correction velocity.

If set to 0, two objects interpenetrating each other will not be pushed apart.

double gazebo::physics::ODESurfaceParams::minDepth

Minimum depth before ERP takes effect.
