Why do we add textures to triangles?
*

1 point

It's a way to add more 'data' into our scenes that is relatively cheap when compared to adding additional geometry. Typically a texture will be used to add surface detail to a triangle (though sometimes it may be used to compute or store additional information).

Can we 'always' map a texture perfectly around geometry?
*

1 point

Yes, it will always work.

No, distortion can become a problem when wrapping a 2D texture around a 3D shape. The classic example is something cartographers have struggled with when making globes and accurately mapping countries on it without distorting their size to make them appear much larger or smaller than their actual size.
