Long name (short name) Argument types Properties
-create(-cr) create
Creates a new rigid solver.
-current(-cu) create
Sets rigid solver as the current solver.
-interpenetrationCheck(-ic) edit
Checks for interpenetrating rigid bodies in the scene.
-interpenetrate(-i) queryedit
Allows the two rigid bodies listed to interpenetrate. Default: interpenetration is off for all bodies.
-collide(-c) queryedit
Disallows the interpenetration of the two rigid bodies listed. Default: Collide is on for all bodies.
-showInterpenetration(-si) queryedit
Displays the interpenetrating objects in a different color.
-showCollision(-sc) queryedit
Displays the colliding objects in a different color.
-autoTolerances(-at) boolean queryedit
Turns the auto tolerance calculation on and off. The auto tolerances calculation will override the default or user defined values of the step size and collision tolerance value that is calculated based on the objects in the scene. Default: 0 (off)
-stepSize(-s) float queryedit
Sets the solvers step size. This is the maximum size of a single step the solver will take at one time. Range: 0.0004 - 0.100 Default: 0.0333
-collisionTolerance(-ct) float queryedit
Sets the collision tolerance. This is the error at which two objects are considered to have collided. Range: 0.0005 - 1.000 Default: 0.02
-friction(-f) boolean queryedit
Turns friction on and off for the an the objects in the simulation. Default value: on
-bounciness(-b) boolean queryedit
Turns bounciness on and off for the an the objects in the simulation. Default value: on
-dynamics(-d) boolean queryedit
Turns dynamics on and off for the an the objects in the simulation. Default value: on
-solverMethod(-sm) int queryedit
Sets the solver method. The choices are 0 | 1 | 2. 0 = Euler (fastest/least acurate), 1 = Runge-Kutta ( slower/more acurate), 2 = adaptive Runge-Kutta (slowest/most acurate). The default is 2 (adaptive Runge-Kutta)
-displayVelocity(-dv) boolean queryedit
Displays the velocity vectors. Default value: off
-displayCenterOfMass(-dcm) boolean queryedit
Displays the center of mass icon. Default value: on
-velocityVectorScale(-vs) float queryedit
scales the velocity vector display. Default value: 1.0
-displayConstraint(-dc) boolean queryedit
Displays the constraint vectors. Default value: on
-cacheData(-cd) boolean queryedit
Turns the cache on fall all rigid bodies in the system. Default value: off
-deleteCache(-del) queryedit
Deletes the cache for all rigid bodies in the system.
-startTime(-stt) float createqueryedit
Sets the start time for the solver.
-state(-st) boolean queryedit
Turns the rigid solver on or off.
-contactData(-ctd) boolean queryedit
Turns the contact data information on/off for all rigid bodies. Default value: off
-statistics(-sta) boolean queryedit
Turns the statistic information on/off for all rigid bodies. Default value: off
-rigidBodies(-rb) query
Returns a list of rigid bodies in the solver.
-rigidBodyCount(-rbc) query
Returns the number of rigid bodies in the solver.
