abstract class Model

gamnit :: Model

3D model composed of Mesh and Material, loaded from the assets folder by default

Instances can be created at any time and must be loaded after or at the end of create_scene. If loading fails, the model is replaced by placeholder_model.

import gamnit::depth

var model = new Model("path/in/assets.obj")
model.load

The most simple model is LeafModel, composed of a single Mesh and Material. It can be easily created programmatically to display simple geometries. Whereas CompositeModel is composed of one or many LeafModel and is usually loaded from the assets folder as a ModelAsset. Instances of ModelAsset must be in the format OBJ and MAT, and their texture in PNG or JPG.
