Elastic Deformation Question

[wenhao_zheng]

Hi!

Use the soft body's deformation resistance setting. At 1, the softbody will be as rigid as the solver's settings allow it to be: the larger your budget for simulation - more substeps, more iterations - the higher the rigidness it will achieve. As you reduce deformation resistance, the softbody becomes softer.

Note that the resolution of your blueprint and the simulation settings (ObiFixedUpdater substeps and Solver iterations) have an influence on the maximum rigidness of softbodies.


Elasticity is not the same thing as deformation, I'm unsure of what you want to do. If you want to read back the amount of deformation, this is done by reading each constraint in the softbody. Constraints contain a 3x3 deformation matrix that encodes deformation in their neighborhood. See the DeformationGradient sample scene for an example of this.

If you want to set the elasticity (that is, how much the softbody is allowed to deform), this is also done per-constraint. See:

kind regards,

Thank you very much, I understand better than before. I will try your suggestions further!
