viewport
The rectangular region of the screen that your rendered image gets mapped onto.
After geometry is transformed, the GPU needs to know where on the target surface to place it. The viewport defines that destination rectangle — its position and size — mapping the abstract coordinate range onto real screen pixels. Splitting a window into multiple viewports lets you render different scenes side by side.
