Forward rendering is what OpenGL traditionally uses. It renders directly to the backbuffer one object at a time shading each one as it goes.
ForwardRenderer is a single leaf FrameGraph tree which contains a Viewport, a CameraSelector, and a ClearBuffers. The ForwardRenderer has a default requirement filter key whose name is "renderingStyle" and value "forward". If you need to filter out your techniques, you should do so based on that filter key.
By default the viewport occupies the whole screen and the clear color is white. Frustum culling is also enabled.
camera : Entity
Holds the current camera entity used to render the scene.
Note: A camera is an Entity that has a CameraLens as one of its components.
clearColor : color
Holds the current clear color of the scene. The frame buffer is initialized to the clear color before rendering.
externalRenderTargetSize : QSize
Contains the size of the external render target. External render targets are relevant when rendering does not target a window surface (as set in surface).
frustumCulling : bool
Indicates if the renderer applies frustum culling to the scene.
gamma : real
Holds the gamma value the renderer applies to the scene.
surface : Object
Holds the current render surface.
viewportRect : rect
Holds the current normalized viewport rectangle.
