RenderCamera
|
|
----------------
|
|
This header file describes the RenderCamera class.
|
|
|
|
A RenderCamera is the object responsible for providing a rendering position,
|
|
orientation, and perspective transformations. A RenderCamera exists within a
|
|
RenderScene and outputs all data to the friend class, RenderView.
