Free GPU resources. Without an argument, everything the renderer created is freed and the renderer is unusable afterwards. With a geometry, material or texture, only that object's resources are freed; they are recreated on the next render if still in use.
Optionalobject: BufferGeometry | Texture | MaterialColor the frame is cleared to before drawing (default black)
Optionalalpha: numberDevice pixel ratio applied by setSize (default 1)
Resize the drawing surface in CSS pixels; pixelRatio is applied
A renderer that draws nothing and needs no canvas. It updates the world matrices like a real renderer and records what it was asked to do, so scene code can be tested without a GPU.
