/**
|
|
* Example scene using QtkWidget to render 3D models and simple geometry within
|
|
* QtOpenGLWidgets. This scene also shows some examples of using GLSL shaders to
|
|
* apply the basic lighting techniques leading up to Phong.
|
|
*
|
|
* The Qtk::Scene base class provides containers for N pointers to MeshRenderer
|
|
* and Model objects. We can create and insert as many as we like within this
|
|
* child class implementation. This child class does not need to manually draw
|
|
* objects inserted into these containers. The child class would only need to
|
|
* update uniform or other data that may change per-frame.
|
|
* See scene.h and `init()` for more information.
|
|
*
|
|
* To modify the scene objects should be initialized within the `init()` public
|
|
* method. Any required movement or updates should be applied within `draw()` or
|
|
* `update()`.
|
|
*
|
|
* To create your own Scene from scratch see Qtk::Scene.
