Topological shape optimization of 2D block

Description

This code simulates and renders a constrained system of 2D points connected together via elastic massless rods (links) forming a 2D block of a solid material.

The links are removed/deactivated from the system, once their change in length is less than a predefined small number. Thus, the block losses its mass in those regions, where the construction have low values of elastic strain.

The links or rods are rendered and color-coded w.r.t. their value of strain. The colormap is computed on the go as a weighted sum of 3 slightly overlapping Gaussians that contribute to 3 principal color values: blue, green and red.

The physics simulation is based on time-explicit integrating (via the Verlet's formula) of momentum equations for each particle and resolving their connections moving the particles in opposite directions along the link.
