What is sprite batching
1 point
Drawing multiple sprites without having to change state
A technique for creating an illusion of perspective by having a scrolling background.

Can I use some(i.e. at least 1) of the same tricks for 3D rendering as those in 2D? (Things like global illumination, vertex cache optimization, etc.)
1 point
Yes
No
Is it possible if I am drawing 1000000 sprites, and I use a poor sorting algorithm that sprite batching will actually slow down my rendering?
1 point
Yes, the overhead of sorting could negate the effects of rendering so many sprites. Additionally, if all of those sprites are unique, sprite batching will not help.
No, sprite batching always speeds up my program!
Clear selection
Why reason is best for choosing vector graphics over raster graphics for rendering?
1 point
Vector graphics can 'scale' to any dimension. That means when we zoom in our out, or change resolutions, the game can remain consistent.
Vector graphics make it easy to create very complex characters. For example, I can easily create a realistic self-portrait of myself.
