A birdcage (or bird cage) is a cage designed to house birds as pets. Antique (or antique-style) birdcages are often popular as collectors' items or as household decor but most are not suitable for housing live birds, being too small, or of unsafe materials or construction.ood quality cages designed for pet birds are more suitable. Most parrot cages are made or wrought iron and painted with a non-toxic paint referred to as powder-coating. However, the newest trend in the market is cages made of solid stainless steel.
A viewport is a 2D rectangle that defines the size of the rendering surface onto which a 3D scene is projected.
For example, to create a split screen game, you might render multiple viewports to a single render target. The viewport dimensions do not correspond to the display dimensions, which are determined by the DisplayMode property, or to the game window, which is determined by the ClientBounds property. Use the Clear method to reset a render-target surface.
