\title Adding Models
A Model component loads mesh data from a file. You can modify how the
component is shaded by adding materials to the model.
A model can load static meshes from storage or one of the built-in primitive
types: cube, cone, cylinder, plane (rectangle) or sphere. You can drag and
drop a model from the \uicontrol Library to a 3D scene.
\image studio-qtquick-3d-components.png "Library view QML Types tab Qt Quick 3D section"
You can change the model type in the \uicontrol Source field in the
\uicontrol Properties view. Select the \inlineimage plus.png
button to add custom model types to the list.

To enable picking the model against the scene, select the
\uicontrol Pickable check box. Picking transforms the screen
space x and y coordinates to a ray cast towards the specified
position in scene space.
To use the geometry of this model when rendering to shadow maps, select the
\uicontrol {Casts shadows} check box. To allow casting shadows on the model,
select the \uicontrol {Receives shadows} check box.
\section1 Tessellation
To dynamically generate additional geometry for the model, select the
tiling mode in the \uicontrol {Tessellation mode} filed. Tessellation
is useful when using a displacement map with geometry, or to generate a
smoother silhouette when zooming in. You can select either a Phong or
an NPatch tessellation generator.
Specify an edge multiplier to the tessellation generator in the
\uicontrol {Edge tessellation} field and an inner multiplier in
the \uicontrol {Inner tessellation} field.
To display a wireframe that highlights the additional geometry created by
the tessellation generator, select the \uicontrol {Enable wireframe mode}
check box.
\section1 Adding Materials to Sub-Meshes
A model can consist of several sub-meshes, each of which can have its own
material. Select the material from the list in the \uicontrol {Materials}
field. Select the \inlineimage plus.png
button to add materials to the list. For more information about materials,
see \l {Using Materials and Shaders}.
