dmech

dmech stands for "D mechanics": it is a real-time 3D physics engine written in D language, capable of simulating rigid body dynamics. It is more suitable for computer games than scientific simulations: the goal is to convince a player, rather than giving accurate results. dmech is GC-free and fully platform-independent, it can be used with any API or graphics engine. Currently dmech is in early stages of development and not considered for production use.

Features

Already implemented:

  • Impulse-based rigid body dynamics with iterative SI solver
  • High-performance collision detection (MPR algorithm)
  • Basic geometry shapes (sphere, box, cylinder, cone, ellipsoid)
  • Support for any convex shape defined by support mapping
  • Multiple geometries per body
  • Arbitrary static trimeshes (collision detection is optimized via BVH)
  • Body constraints: distance, angular, slider, ball-socket, prismatic, hinge
  • Persistent contact cache
  • Ray cast support
  • Partial C API (will be finished soon)

Planned in future:

  • More shapes (capsule, plane, convex hull, etc.)
  • Minkowski sum shape
  • Force fields
  • Convex cast
  • In long-term: vehicle engine, particles, soft-body physics, OpenCL support

Dependencies

dmech heavily relies on dlib - a collection of utility libraries for D, including linear math and computational geometry functionality (it is recommended to use master, because dmech usually depends on latest repository changes).

Documentation

See tutorials.

Usage examples

See demos/new directory. All examples use DGL for rendering.

For real-world usage demo, check out Atrium, a physics-based action game.
