MegaPOV

collisions and stress visualization

The scene collide_fast.pov demonstrates the simulation of collisions between different simulation elements. The simulation system provides techniques to speed up these collision calculations like grouping of elements and automatic bounding and hashing.

Furthermore it shows how the visualization macros coming with MegaPOV can be used to texture the structures with colors representing the deformation of the connections.

cloth simulation

The scene cloth_fixed.pov shows how the movement of cloth and similar materials can be simulated. Apart from rectangular sheets you can of course also simulate other shapes of cloth including clothes.

viscoelastic connections

MegaPOV 1.2 introduces a new type of connections that simulate viscoelastic material properties.

The scene viscoelastic.pov demonstrates the use of such connections to simulate the effect of material relaxation. The bar in the animation deforms under its own weight while being fixed at the ends and the deformation increases over the time.

colliding particles

The scene particle.pov shows how simulations of particle systems including collisions between particles can be done using the MegaPOV mechanics simulation system. By using a bounding/hashing system for collision calculations even large numbers of particles can be simulated efficiently.

custom forces

The scene glow_sim.pov demonstrates the use of custom forces to influence the movement of masses. Near the ground the particles of this simulation - displayed using the MegaPOV glow effect - are dragged towards the hole in the middle. Custom forces can be specified with POV-Ray's user defined functions and can be applied to all or individual masses.

rolling and sliding

The scene roll.pov demonstrates interaction of simulation objects with the environment and how the material properties affect this interaction, in this case the transit from sliding to rolling or a cube on an inclined surface.

hysteresis curves

The scene hysteresis.pov plots the hysteresis curves (stress-strain relation) of a single connection or a 2d grid under a periodic movement.

You can observe how different types of connections result in different movement and different hysteresis curves, esp. at the beginning.
