“…Therefore, the spring stiffness is distributed based on an estimation algorithm which has been commonly employed to estimate the behaviour of a membrane with irregular mesh topology (Gelder 1998;Maciel et. al 2003;Lloyd et al 2007;Arnab and Raja 2007) The volume spring stiffness defines the level of elasticity of virtual space or volume represented by the node, which is also based on the explicit volume discretisation.…”

This paper introduces a surface alternative to the volume model commonly employed in soft object simulation. This is inspired by a significant interest in employing the surface data due to its simplicity. However, there are issues in properties estimation and volume preservation. Therefore, the aim of the ongoing research includes exploring the potential of a surface mass spring model with shape-preserving springs for volume simulation. The approach illustrates the possibility of deriving the spring stiffness at runtime based on the real material properties as well as achieving a global shape deformation despite the non-existence of internal volume. The proposed scheme can be further explored to address other material properties.
