A .PMD model is a 3D object which has movable parts controlled by "bones" which can be be posed in any matter. For example, a .PMD model in the form of a human has arm and leg bones which you can manipulate and a .PMD model in the form of a car has movable parts such as "wheels", "windows", "windshield wipers etc". Think of .PMD models as "action figures/dolls/toys with poseable joints"
In the screenshot example, I have posed three .PMD models.
- A .PMD model of Rin's and Len's Roadroller
- A .PMD model of Rin Kagamine riding the bulldozer down
- A .PMD Len Kagamine model trying to escape his inevitable pain
