Detailed Description

Forward rendering is what OpenGL traditionally uses. It renders directly to the backbuffer one object at a time shading each one as it goes.

QForwardRenderer is a single leaf FrameGraph tree which contains a QViewport , a QCameraSelector , and a QClearBuffers . The QForwardRenderer 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.
