\title Qt3D: Basic Shapes C++ Example
\ingroup qt3d-examples-cpp
\brief Shows four basic shapes that Qt3D offers.
The Basic Shapes examples shows four basic shapes that Qt3D offers, a torus,
a cylinder, a cube and a sphere. The example also shows how to embed a Qt3D scene
into a widget and connect with other widgets.
\image basicshapes-cpp-example.jpg
As an example let's go through how to set up a torus mesh. First instantiate
the \c QTorusMesh, and then set the mesh specific parameters, that for torus are
radius, minor radius and how many rings and slices.
\snippet basicshapes-cpp/scenemodifier.cpp 0
The size and position of the torus can be adjusted with transform components.
We create scale, translation and rotation components and add them into the
\c QTransform component.
\snippet basicshapes-cpp/scenemodifier.cpp 1
To change the diffuse color of the mesh we create a \c QPhongMaterial and set
its diffuse color.
\snippet basicshapes-cpp/scenemodifier.cpp 2
The final step is to add the torus into an entity tree, and we do that by creating
a \c QEntity with parent entity and adding the previously created mesh, material
and transform components into it.
\snippet basicshapes-cpp/scenemodifier.cpp 3
You can control the visibility of the entity by defining if it has parent
or not, i.e. whether it is part of entity tree or not.
