Interactive matter simulation using LATTICE.

About

LatticeLab is a project built around the LATTICE molecular dynamics engine for interactive simulation and exploration of atomic behavior.

The idea is simple:

define how atoms interact and observe the resulting behavior

Without any animations made in advance.
Only potentials and forces between them.

But that is already enough for the system to behave very much like real matter.

What You Can Observe

• self-formation of crystals
• particle diffusion
• lattice oscillations, waves, and phonon-like vibration
• emergence of grains and domain boundaries
• packing defects and local lattice distortions
• nucleation of inhomogeneities
• waves, phonons, and interference
• local ordering and structural breakdown
• behavior resembling solids, liquids, and transitional states
• relaxation after collisions, compression, or parameter changes

What Is Planned

• molecular modeling
• chemical reactions
• metals and alloys
• charged particles and ions
• [x] electrostatic interaction (Coulomb)
• electricity and conductivity
• simple models of nuclear interactions
• radioactive decay
• energy transitions
• biochemistry
• proteins and folding-like behavior
• DNA and other chain-like molecular systems
• project tree and module map

Why?

Physics is often presented as equations first.

Here, you can watch complex behavior emerge from simple interaction rules:

• for educational purposes
• for experimenting
• to understand how the world around us works

Build

The project uses CMakePresets.

Typical local build:

cmake --preset debug
cmake --build --preset debug

Release build:

cmake --preset release
cmake --build --preset release
