Constructor Detail

ReducedDeformableBody

public ReducedDeformableBody(Vector3f[] locations,
                             float[] masses)

Instantiate a deformable body with the specified nodes. The new body is not added to any physics space.

Parameters:

locations - the initial node locations (not null, alias created)

masses - the initial node masses (not null, each ≥0, alias created)

Method Detail

getLinearVelocity

public Vector3f getLinearVelocity(Vector3f storeResult)

Copy the rigid velocity.

Parameters:

storeResult - storage for the result (modified if not null)

Returns:

a velocity vector (physics-space units per second in physics-space coordinates, either storeResult or a new vector)

isReducedModesEnabled

public boolean isReducedModesEnabled()

Test whether reduced modes are enabled.

Returns:

true if enabled, false if rigid-only

pinNode

public void pinNode(int nodeIndex)

Pin a node.

Parameters:

nodeIndex - the index of the node (≥0)

setDamping

public void setDamping(float alpha,
                       float beta)

Alter the Rayleigh damping parameters.

Parameters:

alpha - the desired alpha value (default=0)

beta - the desired beta value (default=0)

setLinearVelocity

public void setLinearVelocity(Vector3f velocity)

Alter the rigid velocity.

Parameters:

velocity - the desired value (not null, unaffected)

setReducedModes

public void setReducedModes(int numReduced,
                            int numFull)

Alter the number of modes.

Parameters:

numReduced - the number of reduced modes (default=0)

numFull - the number of full modes (default=0)

setReducedModesEnabled

public void setReducedModesEnabled(boolean enable)

Enable/disable reduced modes.

Parameters:

enable - true to enabled reduced modes, false for rigid-only (default=true)

setStiffnessScale

public void setStiffnessScale(float scale)

Alter the stiffness scale.

Parameters:

scale - the desired scale (default=1)

newEmptySoftBody

protected void newEmptySoftBody()

Create an empty btReducedDeformableBody for this ReducedDeformableBody, using the pre-existing worldInfo. The pre-existing btReducedDeformableBody (if any) will be destroyed.

Overrides:

newEmptySoftBody in class PhysicsSoftBody
