Class IntModelInstance

java.lang.Object
gaiasky.util.gdx.model.IntModelInstance
All Implemented Interfaces:
IntRenderableProvider
public class IntModelInstance extends Object implements IntRenderableProvider
An instance of a IntModel, allows to specify global transform and modify the materials, as it has a copy of the model's materials. Multiple instances can be created from the same IntModel, all sharing the meshes and textures of the IntModel. The IntModel owns the meshes and textures, to dispose of these, the IntModel has to be disposed. Therefor, the IntModel must outlive all its IntModelInstances

The IntModelInstance creates a full copy of all materials, nodes and animations.

      public void calculateTransforms()
      Calculates the local and world transform of all IntNode instances in this model, recursively.
