MultiStepAnimationLoop

This component belongs to the category of AnimationLoop.

The MultiStepAnimationLoop derives from the DefaultAnimationLoop. This animation loop is different due to the fact that it allows – at each iteration – for running several collision (collisionSteps), and within each of these collision steps, several integration sub-steps can be computes (integrationSteps).

Data

The MultiStepAnimationLoop has the following data:

• collisionSteps: the number of collision steps computed within one time step
• integrationSteps: the number of time integration (time sub-steps involving the physics resolution) computed within one time step
• computeBoundingBox: a boolean defining whether the global bounding box of the scene is computed at each time step. Used mostly for rendering.

Usage

The MultiStepAnimationLoop has no pre-requisite.

Note that this MultiStepAnimationLoop does not handle constraints solved using Lagrange multipliers.

Example

This component is used as follows in XML format:

<MultiStepAnimationLoop collisionSteps="10" integrationSteps="2" />

or using SofaPython3:

node.addObject('MultiStepAnimationLoop', collisionSteps='10', integrationSteps='2')
