Parameters
[in]_keyString key Below is a list of _key parameter definitions:
  1.

  2. "iters" (int) - number of LCP PGS iterations. If sor_lcp_tolerance is negative, full iteration count is executed. Otherwise, PGS may stop iteration early if sor_lcp_tolerance is satisfied by the total RMS residual.
  3. "sor" (double) - relaxation parameter for Projected Gauss-Seidel (PGS) updates.
  4. "contact_max_correcting_vel" (double) - truncates correction impulses from ERP by this value.

  7. "min_step_size" (double) - minimum internal step size. (defined but not used in ode).
  8. "max_step_size" (double) - maximum physics step size when physics update step must return.
