Class Model

Definition

Namespace:

Tizen.NUI.Scene3D

Assembly:

Tizen.NUI.Scene3D.dll

Model is a Class to show 3D mesh objects. Model supports glTF 2.0 and DLI model formats. Physically Based Rendering with Image Based Lighting is also supported.

Implements

System.ComponentModel.INotifyPropertyChanged

System.IDisposable

Remarks

Since NUI uses a left-handed coordinate system, loaded models are transformed into a left-handed coordinate system with Y pointing down. The Animations defined in the glTF or DLI are also loaded and can be retrieved by using GetAnimation(uint) and GetAnimation(string) methods. The number of animation is also retrieved by GetAnimationCount() method.

Model also supports Physically Based Rendering(PBR) with Image Based Lighting(IBL). For the IBL, two cube map textures(diffuse and specular) are required. Model supports 4 types layout for Cube Map: Vertical/Horizontal Cross layouts, and Vertical/Horizontal Array layouts. And also, ktx format with cube map is supported.

The model and IBL textures start to be loaded asynchronously when the Model object is on Window. ResourcesLoaded signal notifies that the loading of the model and IBL resources have been completed. If Model or IBL is requested to be loaded before the other loading is completed, the ResourcesLoaded signal is called after all resources are loaded. GetAnimation(uint) and GetAnimation(string) methods can be used after the model loading is finished.

By default, the loaded mesh has its own size and PivotPoint inferred from position of vertices. The PivotPoint can be modified after model loading is finished. If user set size property, the mesh will be scaled to the input size. Default value of ParentOrigin of the Model is Center.

Examples

Model model = new Model(modelUrl)
{
    Size = new Size(width, height),
};
model.ResourcesLoaded += (s, e) =>
{
    model.PivotPoint = new Vector3(0.5f, 0.5f, 0.5f); // Use center as a Pivot.

    int animationCount = model.GetAnimationCount();
    if(animationCount > 0)
    {
        // Play an Animation of index 0.
        model.GetAnimation(0).Play();
    }
};
model.SetImageBasedLightSource(diffuseUrl, specularUrl, scaleFactor);
window.Add(model);

Constructors

Model(string, string)

Create an initialized Model.

Declaration

public Model(string modelUrl, string resourceDirectoryUrl = "")

Parameters

Type	Name	Description
string	modelUrl	model file url.(e.g. glTF, and DLI).
